I think the biggest battery drain for the phone is the 4G radio. Is it possible turns it off and use 3G?
you can't. you either have data on or data off. What drains the battery more is having your phone switch between edge/3g/H/H+ automatically.
Our phones are not like an lte phone. Our 4g is really just souped up 3g so you either get edge our 4g.

When your phone is switching from 3G to H (which you don't see anymore, all you see now is E or 4G) your not switching technologies. Back when you saw 3G vs H it just ment your phone was idle and not transferring data. When H came on, you were doing data.
There is also no difference in switching from HSPA to HSPA+. It is the same data, just one is a little faster.
Now, before T-Mobile launched HSPA, yes, there was Rev99 data which was slow like Edge and your phone only displayed 3G. But that has been gone for a long time.
As far as switching from GSM to UMTS (Edge data to HSPA data) yes, that will cause battery drain if it is continuous. This is because the phone is trying to reestablish a data connection.
In summary, you no longer see 3G on your phone, only 4G which replaces the 3G/H icons. When you are connected to 3G you are NOT switching technologies when you use HSPA data, your just activating data thus you are NOT draining more than normal amounts of battery. When you switch from 2G to 3G you ARE switching technologies so if your continuously bouncing from 2G to 3G that can cause increase in battery drain.

No, everyone is VERY confused with this. They are the same radio. HSPA+ is the data side of 3G. T-Mobile is just calling it 4G because Sprint got away with hit with their WiMax. EVER cell site on T-Mobile's network has HSPA activated. This means there is no longer 3G data.

Again, people do not know true definitions.
HSPA - 3.5G
WiMax - 3.5G
LTE - 3.5G
Ture 4G technologies are:
WiMax 2 and LTE Advanced.
NO CARRIER IN THIS NATION HAS EITHER OF THOSE TECHNOLOGIES ACTIVATED!!!
Sprint turned on WiMax (not 2nd generation) and called it 4G. So why not follow suit do the same thing. It's all marketing.

well, the drain is likely due to dual cell usage. You can disable dual cell which will knock your top speed down to 21 (theoretical) Mbps. So get to service mode select Debug Screen - > Phone Control -> NAS Control -> RRC(HSPA) Control -> Change RRC Revision ->
DL speeds for items listed are as follows:
R99 = 384kbps
Rel 5 = 7.2
Rel 6 = 14.4
Rel 7 = 21
Rel 8 = 42
hope this helps
Couldn't you force your phone on the 850 UMTS frequency? I say this because I thought HSPA /+ran on the 1700 and 2100 bands so theoretically you could actually be on 3G. I know jugs rom allows you to switch the data icons displayed to 3G for UMTS and H/4G for HSPA /+

T-Mobile doesn't use/have 850 range.
Let me see if I can explain this a little better. T-mobile launched their 3G network on a UMTS platform utilizing WCDMA technology. It's like Verizon and Sprints CDMA but with the W which stands for Wideband. CDMA stands for Code Devision Multiple Access. Wideband is what allows T-Mobile to have such high data rates. Standard CDMA has a 2.5MHz bandwidth while WCDMA has a 5MHz bandwidth for each carrier they are utilizing. Currently, most (not all) major cities have dual carrier launched so those sites are actually using 10MHz of bandwidth. This allows for 42Mbps speeds. 21 for each carrier. We are actually starting to deploy 3rd carrier which will allow 1 carrier just for voice so the full 42Mbps is use solely for data. 84 is a COMPLETELY different story and I will not bother with that for now.
Moving on. When T-Mobile built their network they built it with HSPA in mind. You see, HSPA and HSPA+ are add on data technologies that work on a WCDMA network. They are NOT a separate signal to your phone. Following? Hope so! So, with that said, when your device is connected to a 3G cell site, the data available is HSPA+ and the voice is over what you are calling 3G. They are, in fact, the same signal.
HSPA/HSPA+ data is on the same signal as your 3G voice. You are NOT receiving 2 signals. You CANNOT separate them.
Now, on to frequencies. There are 2 modes that you can run WCDMA in, full duplex and half duplex. T-Mobile decided to go with full duplex. I'm assuming (low man on the totem pole here so don't know for sure) this was to have greater data rates. This is why T-Mobile uses 2 frequencies. 1 in 1700 band for transmit, 1 in 2100 band for receive. This is also where T-Mobile differentiates from ATT (and exceeds! ) because ATT went with half duplex and only uses 1 frequency. So, T-Mobile phones have the ability to transmit and receive at the same time while ATT phones do not.
With all of that said, and hopefully understood, you should now know that it DOES NOT MATTER WHAT THE FRIG ICON YOUR PHONE SHOWS!!!!. Sorry, been trying to get that point across. The firggin icon doesn't not mean ****. The fact that you can have a 3G icon and a separate H does not mean ****. If you do have separate 3G and H icons like older T-Mobile phones and you can see it switching that is because while your phone is idle (NO DATA) it will display 3G. While your phone is doing data (ON THE SAME CONNECTION) it will display H. It is a simple indicator to let you know you are using HSPA data.
T-Mobile did away with both icons and replaced them with the 4G icon when they went to the 4G ad campaign. Get it, got it, good!

I don't think your actually disabling the 2nd carrier. I think your just limiting the max data rate your phone will do. As I previously stated, the phone will connect to what the cell site has. You will always be connected to a 10MHz bandwidth if the site is a dual carrier site.

Was trying to give a simplistic explanation. I guess next time I will just link wikipedia.
The whole point of the discussion was that you cannot turn off the HSPA on your phone and use just 3G. I have not messed with the settings you are suggesting and I don't know that I would as inexperienced users can mess their phones up in those menus. I suppose you could force your phone to R99 mode and that might work but forcing to 21Mbps only I still think you will be using both carriers when using data. Will do testing and report back.

NP. shouldn't have fired back that hard. Technically you only get DC if their is enough capacity on the site so its not a given. You & Allgamer are correct there is no "4G" radio its all one radio on the chip, however changing that setting actually should affect the software which i'll give a brief primer on.
R99 = 1 code with a spreading factor of 16 (surprisingly probably the least power efficient of the group)
HSDPA (7.2) = 10 codes with spreading factor of 16 (in our case likely the most efficient power wise)
HSPA (14.4) = 15 codes with spreading factor of 16
HSPA+ (21) = 15 codes with spreading factor of 16 & 64QAM
HSPA+ (42) = HSPA+(21) * 2.
so with the phone not having to decode 64QAM + using less codes the CPU shouldn't have to ramp up as much to process the data.

I totally agree with this. I'm still not convinced, though, that switching form single to dual carrier is doing much as far as battery drainage. It's not like switching modes between GSM and UMTS or LTE and CDMA (Verizon/ATT world) and trying to reestablish on the network. I mean I guess it could cause a little but something is my brain is just saying that the switching isn't doing that much. Now doubling the bandwidth and data rate, yeah, that is definitely increasing battery usage but the switching itself I just don't know.
Honestly I get mixed battery life depending on my daily usage so testing would be hard. That is unless it's huge differences. I set my phone to Revision 8 and see it its huge improvements.
On a side note, and could just be that phone, but 2 of my friends have Thunderbolts and they get like 2-4 hours of battery life. Something WILL have to be done to fix battery life on LTE.
Well, as somebody said i tried the service mode and got too excited and ****up alot of stuff, wiped and installed jug again but looks like the settings got saved . Anyway to reset all the settings there?

It also says RRC: IDLE, BAND 5 in basic info
I messed up with Fake Security something, Antenna/adc, network control
Edit: Putting the sim that came with the phone in, it connected and showed dbm but then after 1min it just had an x on the network bars.

I feel like mine said band 4 earlier today but I cant be for sure. I don't have 3G at my house so I can't test till tomorrow.
You could always try reflashing the phone with odin and stock to see if that fixes those defaults but I'm not sure where they are written. Definitely not in the ROM. Maybe the bootloader or radio image have this information stored so flashing stock oden .tar may fix it? Sorry, I really don't know and this is EXACTLY why I said people shouldn't be messing with these settings.

well... i guess in this case too much info is a bad thing. My suggestion was to TOUCH ONLY the RRC settings ... anything else is a crapshoot
yes T-MOs 3G/4G is "UMTS Band IV"
and for future note... if you don't know what your doing and your screwing around in service mode... take SCREENSHOTS before you mess with anything. Or have a buddy with a phone that is untouched.

Reverting the setting back doesn't/didn't do anything for me. I had to flash stock odin rom+recovery
I know someone said previously that the "4G" icons don't mean much as it will usually show "E" or "4G". However, my phone showed "3G" the other day while I was at home and I only saw this once. Someone on another board said that means it was picking up 1900mhz WCDMA as supposedly T-Mobile is starting to use HSPA on 1900mhz in certain areas. Is that correct?

Hi all,
I"m new here, with a quick question based on my usage today on both the Bell and Rogers network.
I unlocked my HTC Desire Z this afternoon, and I tried it out on Rogers to see what the speeds were like. It has been an odd experience. Here's the background, and my question is below.
Background:
- Aside from being unlocked, it is as originally shipped from Bell (e.g. no root access, ROM hasn't been flashed etc.)
- APN settings were taken from Rogers' own website (e.g. using rogers-core-appl1.apn).
- Speeds tested in downtown Toronto.
Experience so far:
Bell
I get a solid HSDPA indicator all the time (save elevators etc., when there is no connection). I can remember seeing a 3G connection icon perhaps once on Bell since I got it last week. Speeds are very good, four to five bars most of the time
Rogers
I get a solid 3G icon almost all of the time, except when I'm using data, in which case it seems to switch over to the HSDPA icon. Literally, it will show a 3G, and then if I try to browse the web, the icon will immediately switch to an H from a 3G and the web page will load quite quickly.
I was concerned that it was dropping the HSDPA connection frequently, and using 3G instead -- changing towers constantly. So I tried speedtesting it. The results were completely opposite what I expected.
Speedtest Results:
Using the Speedtest.net app (from Ookla) testing against the same Oakville, ON server from Toronto, I'm getting speeds dramatically faster on Rogers. I did three speedtests for each network.
Bell:
Fastest Down: 3411 kbps Fastest Up: 1633 kbps
Slowest Down: 1969 kbps Slowest Up: 1331 kbps
Rogers:
Fastest Down: 5740 kbps Fastest Up: 3766 kbps
Slowest Down: 5405 kbps Slowest Up: 1551 kbps
Ping latency was generally slightly higher on Rogers than Bell.
Question
Does anyone understand why, on Rogers, the Desire Z would be showing a 3G until data is requested, at which time it swaps over to show an H icon (e.g. HSDPA), whereas on Bell, it shows a constant HSDPA connection?
I would have thought that it would be slower on Rogers since it was showing 3G and then the icon switches to H, but I'm guessing that the icon switch isn't really reflecting what's going on, since the speeds are faster when this icon switch occurs. Any ideas?
Many thanks in advance!
TF
Its not just the Desire Z but also most smartphones on rogers. i had a samsung galaxy and it did the same thing. However, (correct me out there, if im wrong) But i remember reading the HSDPA was inbetween 3g and 3.5g?...i dont remmeber but to me i know that Rogers is faster, my brother has a Bell phone and my speeds were always faster.
heres a bit of help i found
HSDPA is actually one of the 3G protocols.
In everyday language HSDPA is often referred to as much faster than (basic) 3G so I would call it much faster as well.

Not sure there really is a 3.5G as such, but if there is, then HSDPA is it. It provides faster speeds than the standard 3G (UMTS) protocols. There's also HSPA+ coming out, which is even faster. HSPA+ isn't 4G, although confusingly some carriers in the US (T-Mobile I think ?) are referring to it as such.
On O2 in the UK, I get the same effect, holds at 3G then switches to HSDPA when in use. There doesn't seem to be any latency when switching and if it can't achieve HSDPA it remains at 3G. Speedtest returns about 1.5-2 Mbit which is normal.
I can only imagine its a power saving feature as from experience with the Touch Diamond 2 / Touch Pro 2, having HSDPA enabled sucked battery life significantly. I don't remember this happening on those phones either. Seems like a good idea, but would be nice to choose (always on, auto, always off)
I actually used to disable HSDPA and use 3G exclusively and consistently got 2-3 days out of both phones with moderate use. I never missed it.

That must be it -- interestingly, I went into the About Phone > Network > Signal Strength menu to check it out. When the icon is showing 3G, the "Mobile network type" is UTMS. When data is being transmitted, the icon immediately switches to H and the "Mobile network type" reports HSDPA.
Very cool -- I'm going to see if this -- by itself -- extends my battery life tomorrow. Thanks for the feedback!
TF
Just FYI -- there has been a dramatic improvement in my battery life on Rogers, compared to what I was experiencing on Bell. Typically, I would be at about 40% battery life left at this point in the day (presumably because I was constantly connected to HSDPA with Bell). Whereas I'm at 80% battery life left with the Rogers 3G connection, and I've still been connected to Wi-Fi for the past five hours and browsing reasonably heavily.
Thanks for your help in sorting this out everybody.
TF
Interesting, as Bell has rolled out several HSPA+ areas, Toronto being one of them, and Rogers still only has HSPA.
What I found odd on my DZ (still on Bells network) is that my Network Mode is GSM / WCDMA auto (never seen this on any other handset I've hand that's been HSDPA) and I understand that the HSDPA networks here are CDMA with a GSM overlay (ie, the need for a SIM card, etc) and I frequently see my icon changing from 3G to H (again, this is only on my DZ), but Bell only has a CDMA EVDO 3G network and the HSPA "3G+" network, there's not really a GSM enabled 3G network.
I'm confused, as on my Telus Milestone, it's constantly H, never once seen 3G appear on it, and Telus and Bell share their network.
Maybe I'm just horribly misinformed.
I donno if it is just me but I seem to be getting ridiculously slow 3G speeds here on my unlocked Desire Z using Rogers. I go to school in Hamilton at McMaster and most of the times the 3G is nigh on unusable because of its speeds. I don't know if it is an app or anything that has caused it because it was never slow when I first got the phone.
I am running the virtuous rom 0.72 atm. I do have half a mind to just factory reset the device adn see if that fixes the issues however I really don't want to lose all of my contacts and other settings that I have on this device.

The same thing happening to me with Galaxy S,and this started a few days ago.
I unlocked my phone and I am using it on Telenor Serbia a and past two weeks it was just H all the time,now it's 3g all the time and when I start browsing it switch to H again and it work well,but why do that,should I be concern?

For me on O2 UK, it depends on the area.. Sometimes its solid 3G, sometimes solid H and sometimes 3G when idle, H when in use.. I guess its the base station software / hardware..

If you've snyced with google then your contacts will just sync back. And I go to school at Mac as well and usually the speeds are really slow inside any buildings... If i don't have full bars then the speed will be crap, otherwise they are fine. But I am on Fido, not Bell.
Also, I thought that Bell didn't have a 2G GSM network? If that is the case then that could be why only H would be appearing...

It could be anything to be honest.. Your operator could have updated the base station.
It seems the phone is designed to do this probably to save power, HSDPA is battery intensive so having the phone in 3G while in standby probably saves quite a bit of power..
You could try emailing HTC with the question before your operator.

Typically, I would be at about 40% battery life left at this point in the day (presumably because I was constantly connected to HSDPA with Bell). Whereas I'm at 80% battery life left with the Rogers 3G connection, and I've still been connected to Wi-Fi for the past five hours and browsing reasonably heavily.
Thanks for your help in sorting this out everybody.

Have you switched your phone to stay in umts only to get this dramatic battery gain?

It could be anything to be honest.. Your operator could have updated the base station.
It seems the phone is designed to do this probably to save power, HSDPA is battery intensive so having the phone in 3G while in standby probably saves quite a bit of power..
You could try emailing HTC with the question before your operator.

From my understanding
GSM = 1G
GPRS= 2G = G
EDGE = 2.5G = E
UMTS = 3G = 3G
HSDPA/HSDUPA/HSPA+=3.5G = H
Since Rogers has all the above mentioned transceiver systems you will see that mostly on the Rogers network Android phones tend to stay on UMTS=3G switching to H only when more data throughput is required.
The battery life is much better on UMTS vs HSDPA hence you will get a better battery life on Rogers vs Bell.
Bell only has a HSDPA/HSPA+ network hence you will only see H
I am not claiming to be a 100% on this
Just my 2 cents by putting together 1 and 1

Nearly there (source Wikipedia),
GSM is 2G
GPRS is 2.5G
EDGE is 2.75G
UTMS is 3G
HSxPA is 3.5G
I would put HSPA+ as 3.75G as its slightly different to HSxPA but would settle for 3.5G
Broadly speaking battery life reduces the higher the generation but I think UTMS can be more efficient than 2.xG sometimes. (NOT HS... which is generally terrible all over hence the behaviour between 3G and H)
I always used to disable HSxPA because of the battery life, its just not easy on this phone. It requires root and editing a prop file..

Hi - I'm looking for some good answers - I think I know the basics...
After much shopping, I bought 2 of these...
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170623785892&ssPageName=STRK:MEWAX:IT
(HTC Touch Pro 2 s - the wife likes for our phones to match so I can teach, set up, etc...)
I think they are called T7373 SEA's South East Asia Versions, and I flashed to 2.07.707/4.49.25.91 radio just fine to get current at WM6.5. (I like factory ROM's - the books work, etc - despite my appreciation for the effort to cook.)
Now - I'm currently ATT, and when they go to Data Plan me, I'm going to T-Mobile prepaid.
So - I get to looking at 3g frequencies - of course!
The book for the device says 900/2100 HSPA/WCDMA.
The sellers' ad says
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 or HSDPA 1700 / 2100
(It's not really clear what the 'or' means)
Now, I'm not *****ing at the seller, I want to really understand, and they knew I was US and they asked ATT or Tmobile.
Would they like have reached into one of three bins, to sell me one of three truly different hardware phones - OR - picked a phone up and flashed it (Radio or full ROM) to my provider, or did they just configure the existing system so it picked Tmobile and its freqs for instance? (When the phone boots, it asks T-Mobile or 2 other Asian-sounding systems) How else could the phones do as advertised? (9/21, 8.5/19, or 17/21)
If the frequencies are not a settings, but a ROM/Radio issue, can I load the 'other US guys' flash and have it work?
If not, does anyone know what really is changed in the hardwares (I imagine the antennas' length might vary by X%, but then here that's % of mms.)
Thanks - great answers and experience really appreciated!!
The device in the picture of the ad is a European unbranded model (RHOD100). It's 3G frequencies are on the 2100MHz band. If they sent you the one pictures, you will not get 3G with any US provider. AT&T uses 850MHz and 1900MHz for their 3G service, while T-Mobile uses 1700/2100MHz. 3G radios are hardware dependent, not software dependent. This means that you must purchase the device that contains the radio for the 3G service you wish to use. They will work on 2G networks anywhere in the world. 3G is really the only difference between carriers.
The AT&T device is the RHOD300 model, also known as the Tilt 2. The T-Mobile version is the RHOD210.
The short answer is that if they send you the exact device in the picture from the ad, you will only be able to get 3G in some parts of Asia and Europe.
The description on the eBay listing is just cut and paste from somewhere (like HTC's website), so that is why it says "or" for the 3G bands. One is for the Euro model, the other is for the Asia model. Either way, neither have the correct bands to give you 3G on AT&T or T-Mobile. And as cajun mentioned, bands are hardware dependent, and there is no way to change it.
If you want 3G on AT&T, you need to buy the AT&T branded Tilt2. But since they will be able to read the IMEI number of the phone (since its ATT branded), they will probably add a smartphone data plan very quickly. So its probably not even worth getting a Tilt2, if you don't want a smartphone data plan. If you want 3G on T-Mobile, you need to buy a T-Mobile branded TP2.
Bottom line, if the phones you bought are unbranded, then they don't have the correct hardware to get 3G on either AT&T or T-Mob.

Hey guys(?) thanks, I think I understand.
So - basically the ad HAS to be a lie, at least for 3G.
So I'm still wondering... What does HTC actually change in the phones - a crystal (I doubt this in modern times), a chip, a pack, an antenna length? There is a small area in the phone that looks 'potted' we used to call it.
They are way too pretty, and way too functional 'as is' to mess with (so I'm not gonna go module or whatever shopping), and we are pretty much 'emergency only' web people (for maps, pizza places, etc) and 2G will be fast enough. The value of a keyboard for texting, the Windows interoperability, and no damn contract is good enough.
We are deciding which ROM level we want before we try ATT to see if they know the numbers... T-Mobile prepaid is the backup plan.

A lie in that it looks like a lazy cut and paste, with either no proof-reading to catch the error, or a seller that does not fully understand what he is selling. They are a high volume seller, and also just used stock photos (not photos of the actual item), so its just a rushed auction posting. I don't think it was an intentional lie meant to mislead you. But if you want to dispute the sale, I think you have very good grounds, since the information in the auction is incorrect, and its actually impossible to tell what exact model (Euro or Asian) they are selling from the description.
AT&T most likely won't be able to correlate the IMEI with the right phone brand/model. But I've seen cases where they think its a smartphone, but the wrong one, and try to add a smartphone plan. I read a post where a guy was using a Nexus One, and their system was reading it as a Blackberry. I think he just told them it was an unlocked dumbphone, and they removed the smartphone plan.
Please Correct me if I'm wrong...
presently I'm using Sprint Touch Pro 2, and I have read on the internet that it is possible to work with AT&T or T-Mobile (which uses different technology other than Sprint's CDMA) after proper unlocking. Is it possible?
Regards.

Yes, but you will not be able to use any other network's 3G service. The best you will get is EDGE on another network.
To follow up...
ATT stuck me on $25 Smartphone within 24 hours. (We went to $15 later, and they dropped us to a $10 cheaper talk plan.) For this particular set of phones, apparently the first 8 or so digits of the IMEI is phone type (which they clearly knew from Tilt 2's) and the rest is item serial number. Couldn't argue there...
Speeds, freqs... I don't get a clear definition of G's anywhere, but I show a H before I long on, and another H with bars as I use data. I have used cellular data at up to 1.1mbs per speed sites - I don't know if that's over E, or G, or H but it seems pretty fast to me. All that's on ATT, when I went to the T-Mobile store and tried their card, the best I got was 200kbs on about 5 tries.
Love the phones, added HTC task manager pulldown, and 1.6 VC from here - THX

G stands for GPRS, and it is a 2G service. It stands for General Packet Radio Service. It is the slowest data service you can get with speeds normally under 50Kbps. It is occasionally known as 2.5G service.
E stands for EDGE. It stands for Enhanced Data Rates for GSM Evolution. It was a revision to the 2G service implementation and features speeds from about 100Kbps to 250Kbps depending on location, service provider, and signal. It is occasionally referred to as a pre-3G technology. It fits in the ITU's definition of 3G, but few people refer to it as such. It is normally marketed as 2.9G.
UMTS (Universal Mobile Telecommunications System) was a revision to the voice service, and did not address much data-wise. This was the first widespread usage of the term and use of 3G. It is normally the service that your device is using when it shows the 3G icon. 3G speeds are normally 350Kbps - 500Kbps.
H stands for HSPA. It stands for High Speed Packet Access. It is one step higher than what is commonly known as 3G.It is also known as 3.5G. It features speeds closer to 1.5Mbps. HSPA is normally grouped in with 3G service when it is being discussed.
As for your test with T-Mobile, that wasn't really a fair comparison since you can't get 3G speeds on a Tilt2 on T-Mobile's network. You can only ever get EDGE service. Therefore, you were comparing AT&T's 3G service to T-Mobile's EDGE service. This is like trying to race a Mustang with a Moped. If you get the Rhod210 model, you will get the faster connection with T-Mobile. There isn't much to compare between AT&T and T-Mobile. AT&T 3G speeds are slower than T-Mobile. The services are also much cheaper on T-Mobile.
THX for reply, I generally understood all the abbreviations, but like you said - the marketing hype really seems to very from the technology.
If I saw, regularly, over 1 mbs and the H bars to the right of the H block, do ya' think I was H/HSPA over 8.5/9/19/21 freqs?

On AT&T it would be HSPA on the 850MHz and/or 1900MHz frequencies. T-Mobile uses 1700MHz for HSDPA and 2100MHz for HSUPA. The frequencies for 2G services are all the same for everyone. This is why you will get up to EDGE service with any GSM carrier, but never 3G service unless you buy a device that explicitly supports that carrier's 3G service.
So I haven't been able to find anything on this yet. I apologize if it's out there and I missed it.
Will the Nitro do a true 3G signal? I ask because I just returned the Skyrocket because it wouldn't. My problem is I work in the Texas oilfield outside of good coverage areas. With my amplified cell booster my old iPhone would go from NO signal to full 3G. One month of the Skyrocket and it wouldn't work. The phone would only do EDGE, 4G, and LTE.
I've ordered the Nitro (will be here tomorrow) because on the AT&T website it's the only LTE phone that comes up when filtering search to show 3G capable devices. I want the LTE phone because when I'm home in DFW the LTE service is amazing.
I know that "all" phones now are "3G compatible", but the Skyrocket (and even my wife's Infuse) would never do anything more than EDGE out there.
I've noticed that some people use different APNs for certain signal options. I'm new to all of this and I'm not familiar with much about android.
Thanks in advance.
f it helps, I have yet to see 3g on mine. 1 month +

Well crap. Do you regularly travel outside of 4G areas where it should drop to 3G?
I'm beginning to think that all of the 4G phones exclude 3G.
I think it's more basic than that. My initial assumption was that if you're in a 3G coverage area on a network/phone with HSPA+, you'll always see 4G, but I could be wrong in my understanding of how the technology works.

TBH, not regularly enough to have a 100% on the 3g thing.
If i may inject my 2 cents:
The Nitro can use the following cellular frequencies:
2G/3G Network GSM 850 / 900 / 1800 / 1900
4G Network HSDPA 850 / 1900 / 2100
4G LTE Network LTE 700 / 1700
so if the cellular area you are in has 3G, and you have an APN for the 3G network, you should have no problems.
You can also scan the area for available frequencies by going to Settings -> Wireless and Networks -> Mobile Networks -> Network Operators -> Search Networks then choosing the 3G provider you use.
To be honest, i have seen my phone roam to the 3G network while travelling to ottawa from hamilton (where i live) via the 401 and Hwy 7 (transcanada). You will NOT see an indicator that you are on 3G, only the bars for signal strength will show up meaning you have a signal for voice. your carrier may offer 2G/3G data but i can't speak on that as i don't live there
Mine does not allow access to that search networks setting. :-(
@scott0: okay, just what _do_ you get under the network operators menu???
again, I do not get access to that menu at all, whatsoever, nada, zilch.
it is greyed out.
ahhh i didn't mean to upset you. The "greyed out" was an important piece of information. so the baseband has you locked out. you might try flashing the baseband image from Malnilion's thread (if you feel adventurous). You have a Nitro HD, with AT&T if i am not mistaken??
I'm not upset, not sure what would lead you to say that. I was simply checking out the navigation you pointed out as I like to see all the nooks and crannies of this device. Upon navigating there, I discovered the menu is not available and pointed that out.
could you try this for me please *#*#4636#*#* then choose Phone Information and hit the left most soft key (settings/menu) and try the Select Radio Band button please?

My phone has that disabled as well. I think it's because we have locked to AT&T? Does it make sense?
The Select Radio Band crashes here too.
@repherb,
You are running the SU640 ROM which unlocks the features you are describing. Most of us are not, so these settings will hidden from us. In other words, stop asking people to do things that don't apply to the stock AT&T/Bell ROM's.
If you would be so kind as to look at in my sig and THIS thread, i am running the Nitro HD ROM. please stop and READ next time before posting. The SU640 ROM is different than the AT&T or Bell ROMs, as you already know.
The reason I asked him to try it is because the option to select networks is greyed out and since i do not have that feature disabled myself, it only stands to reason to ask scott0 to try it on his unit. Just like i was experimenting on my unit as well, yet i have NEVER told anyone to stop saying/telling/doing something. We are all here to experiment and discover new things and collaborate with our peers to accomplish anything we can with this unit.
thank you LiViD.

@ [email protected] & scott0: Okay, i assume you have the option greyed out too, so it stands to reason that the Nitro baseband is locked to that carrier, which means we now have to find a way to experiment on a Nitro with another carrier baseband to see if it allows that option to be available in the normal menus. sound like a plan folks? any guinea pigs out there???

Ok... I have gone round and round and round and round with AT&T on this issue. My data is nearly unusable while on a call. Most of the time it times out, and when it does work, it is ridiculously slow.
I have gone through the stores, technical support, wrote their corporate headquarters (which got no response whatsoever), Twitter, and finally I filed a complaint with the FCC.
The FCC complaint is where I am now, and they want to work with me on this issue. They keep focusing on the towers in my area (although it happens EVERYWHERE), and my phone (even though this is my second phone). Basically I am tired of wasting my time with this issue, and I want to point them to this thread to tell them this this is NOT just me. Maybe it is the Note 2, but I think it is their network. Hopefully this thread will tell me AND THEM.
So with that said, I would love for everyone to post their City/State, and 2 speed tests (one while on a call and one while not on a call). Not moving would be preferable.
I will post mine shortly.

Not sure why you so frustrated. But signal's are suppose to drop while on a call!! Your using data, and yes we can be on the web and be on a call at the same time. I've been doing it since I was first on AT&T. :thumbup:
But I'm thinking it's your area or the modem. Here's my results after reading your post. I decided to go out for breakfast and perform this test to see if it was that BAD! :what:
Here's my results:

Still above 10 mb down. BUT IT DID DROP DRASTICALLY BECAUSE I'M NO LONGER ON LTE CONNECTION.

To answer your question, I am upset because they advertise themselves as being able to use voice and data simultaneously and I can barely use my data while on a call. Most of the time it times out and I constantly have to redo my request. I think my problem is the ability to send data (which include acknowledgements and the request). I don't so much mind that it slows down, but being nearly unusable is a whole other story.

As an RBS Engineer I can explain why this happens to you.
Its due to a few reasons
1. What frequency is 1st carrier in your market 1900mhz or 850mhz
2. How many carriers are in your particular area (the most i have seen is 5 in the major metro areas)
3. How far away the next tower is to you
4. How saturated each carrier is
Whwn testing a new LTE site i will get 30-50mbps download and 20mbps up
Thats cuz im the ONLY one on the carrier at the time.
So a tower is made up of carriers, each carrier has sectors with a corresponding antenna that face a different direction (Alpha Beta Gamma)
You have multiple carriers in areas where theres heavy traffic.
now back to your phone its multi banded 1900, 850, 700/2100(lte)
If your market is 850 first carrier and 850 second carrier your data while on the phone will be almost non existent becuase that band on your phone is in use with your call. But if you have 850 1st carrier then 1900 second carrier or vice versa then your speeds will be decent. For whatever reason when you place a call your data automatically switches to HSPA most likely due to the VOIP on the LTE band leaving only the 3g band for data. Now I dont engineer the network itself becuase I dont understand why LTE isnt left open for data while were on calls.
I dont know if i confused you more or if that helped.
Hope it helped though
Its like a highway
A carrier is a single highway with multiple lanes 850mhz 1900mhz 700mhz(for lte 1st carrier) and 2100 (for lte 2nd)
If your area has only 2 carriers 850mhz and 850mhz its like 2 lanes on a highway going in the same direction and the other side of the highway is blocked
If its 850mhz and 1900mhz but there is heavy traffic and not enough carriers its like bieng stuck in 5 o clock traffic and trying to turn around. Its busy on both lanes so everything is slow
Each carrier adds lanes for traffic in a typical metro area you will see someting like
1st carrier 850mhz
2nd 850mhz
3rd 1900mhz
4th 850 mhz
5th 1900 mhz
LTE 1st carrier 700mhz
LTE 2nd Carrier 2100mhz
Thats a lot of lanes for traffic

Well it seems to happen everywhere that I go which is as far as 70 miles in any direction. The big 3 are in my area (Sprint, AT&T, and Verizon) as well as T-Mobile and Metro (but I am not sure if Metro is their own or they use other carriers).
The major metro areas that I visit are Tampa and Orlando and they do the same thing. I live in a rural area (so the towers are not very saturated), and there is a tower about 1.5 miles (tops) in either direction of me.
I am not sure what frequency my area is. How can I tell?
This is expected. AT&T doesn't support voice over LTE yet, so when you place a phone call the modem needs to switch back to the 3G/Fake 4G HSPA+ network. I'm guessing you just have poor 4G reception. Can you disable LTE and then do a speedtest on the regular 4G network?
Prior to the LTE implementation I was getting far better speeds on the HSPA+ network..
How do I disable LTE to get a current HSPA+ test?

Edit: while on a call I get 1663Kbps down and just 93Kbps up, so this might not be unique to you.

This is expected. AT&T doesn't support voice over LTE yet, so when you place a phone call the modem needs to switch back to the 3G/Fake 4G HSPA+ network. I'm guessing you just have poor 4G reception. Can you disable LTE and then do a speedtest on the regular 4G network?

On HSPA+ I get 2.2 meg down and almost 1 meg up (910k).
FAR better than what I get while on a call in an LTE area.
OK after reading this thread. Do y'all think this problem will be fixed for the Note 3 because I read the note 3 will have the strongest LTE chip available? Or will it be determined on how heavy data traffic is on your frequency?
At&t hasn't supported voice+LTE data. Its the original voice+3G data. Its not the phone.
A given market can be very large it can encompass a whole state. I work in the south texas market which is basically EVERYTHING south of killeen texas. I have driven as far as 6hrs to south padre from austin and I remain in the same market. That was almost 400 miles south. Houston is part of the same market as well as all the way to east to the border of lousiana.

ranger - thanks but that doesn't explain the problems I experienced.

So how can I determine the frequency of my market to answer your original inquiry??
I just got my H815 and I went to Cricket and when I left she had turned on Mobile Data which is good but I had an 'H', so I turn the Network mode to LTE Auto, top option, and it now says 4G, but I thought that it needs to say LTE for top speeds?
I remembered seeing LTE somewhere, but I can't find it again.
So even though it says 4G, am I getting LTE or? The APN seems to be set up correctly.. so?

It will automatically switch to 4G/4G+ mode when the signal is good enough (=LTE, but the display will show 4G or 4G+ for LTE Advanced). If you have "H" or "H+" shown it's because the 4G signal is bad in your area and would probably be slower than a good H/H+ reception
I concur. International unlocked models (like mine) still show 4G, even when you set everything up correctly. Rest assured, you ARE getting LTE, it just doesn't say so on the screen.
As long as your completely sure.... Where can I go to check my signal strength and check my speeds?
I'm only getting 2/5 bars... that's not good..
The signal strength can be checked via Settings -> System -> About phone -> Network. It will show you the mobile network type and signal strength.
As said before the LG G4 will not show "LTE" as icon, but only 4G and 4G+. Also unfortunately there is no option to set it to "LTE" only. Just only "GSM" and only "WDCMA" (at least for my H815 Euro)
See this pic and envy my signal
My Mobile Network Type shows LTE, but right now it's 4G , so I guess when I'm in a better spot, I"ll get 4G+ which is LTE... But as of now I'm only getting 4G because of my signal strength? Which that is -112 28asu.

As said the icon "4G" is LTE, and "4G+" is LTE Advanced, which is faster than LTE

My dads phone, not the H815, shows LTE but is only shows 2/5 bars also. So I guess it just shows he's connected for LTE but is most likely getting only 4G?

Dude, ill explain again, 4G and LTE is the same thing, it's just that every manufacturer might show a different name/icon on it's ROM, the G4 uses the "4G" and "4G+" icons. Some Samsung phones show LTE / LTE+ etc.
Its the same thing Which one you get depends on the backend technology, it's not said that every LTE backend also supports LTE Advanced, even if you are next to it-
Alright, I'll see how it performs. what are usually 4G speeds?
On cricket, 4G speed is 4mbps and their LTE is 8mbps. Not the speeds of AT&T, but we pay half the price so I take the slower speeds. Plenty fast enough for me.

For us picky folk (I'm one that wants to *see* the LTE icon) after root, what can we change the build.prop to to show the LTE on the H815? I know on AT&T branded phones, you add klteatt to the build.prop. Would it be the same to get that icon?
I dont think its that easy, im not sure but if the actual picture are not in the rom its not enough to change some config file, then you would have to replace the pictures in the apk containing them (that would be the easiest way). I personally like the 4G more though, since it scales better than 3 letters and is more readable

This is defined in systemui/values/bools. If <bool name="config_show4GForLTE">false</bool> then it shows the LTE icon. If it is true it shows 4G. As ktwo said in matter of speed these refer to the same network, same speed. There are some confusing infos here around...
same phone (815) in Irish Meteor network (meteor sim): shows 4G and 4G+, Polish Play network (play sim): LTE and LTE+, Polish T-Mobile/Era (Meteor sim roaming): LTE
