I have the Galaxy nexus unlocked and am using it on T-mobile USA, it seems like i am getting 4G (HSPA) coverage less than when I was using my G2X. I was wondering if anyone else was feeling this way? I was also wondering if anyone has gone into the hidden menu (*#*#4636#*#*) under Phone info and experimented with changing the Preferred network type at all? I am currently set to GSM/CDMA auto (PRL) i tried changing it to WCDMA prefered, but it wont stick. I know we have done that in the past for other T-mobile 4G phones to tell the phone to always connect to 4G unless no 4G signal is present.
i too feel like its bad signal on the nexus, i changed to wcdma only though
Did yours stick? I tried to change mine, but if I go back into the hidden menu after I change it, its back to GSM/CDMA auto. My changes dont save......
i'm not noticing any difference from my nexus one really. also not noticing much better download speeds either.
mine sticks for sure
Did you do anything special? I go into the drop down menu select WCDMA preffered, then hit the back button to exit the hidden menu right? There is no save option or anything that Im missing right?
Just tried it again. I can pick WCDMA only and it will stick, but WCDMA prefered wont stick. Interesting....
are you guys getting better signal with WCDMA only or about the same?
i get really crappy 3G reception and sometimes it's so bad that i have to force my phone to stay on edge just so i can make phonecalls.
My phone constantly displays the H, but my speeds are down right despicable. Its near dial up status

I've had no problems with the GN on T-Mobile's network without changing any of the internal settings. In both New York and Arizona I've been getting 3 - 5 Mbps consistently, with peaks of up to 7 Mbps.
One thing I've noticed is that the radio switches to 3G when I'm not using data, but when I load a webpage or ask for data it switches to HSPA+. This is probably to save the battery life, so I'm not complaining.
This seems a relevant place. I just bought my GSM Nexus yesterday on Amazon and got it today. T-Mobile SIM card plugged in, I get terrible reception. I have no signal at all where I'm sitting, whereas my Vibrant and my G2 both had at worst 3G connection.
I'm not a clever man, but I know something is up. I haven't rooted or done anything to my phone. Is there something that I must do to get the phone to work properly?
To reiterate: I have done absolutely nothing but put in the SIM card.
Try a different baseband (search the GN forums for details)…
With the latest baseband (XXLA2) I seem to have better signal than I did on my nexus-s, and the nexus-s did pretty good.

Is there any update to which is the best modem to use for t mobile? Seems like one of my friends is having trouble getting signals in home but he is getting signals outside.

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?

Been through that on another thread..."Select Radio Band" blows up on our Nitro (Force Closes). Bit of a bummer I must say.

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???

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.

Yes, in idle, but we're talking about limiting data here, not idle states. So therefore, if you are connected to a dual carrier site and in a data session you will be utilizing both carriers regardless of your data rate.

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.

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?
Was briefly excited on the arrival of my US version from oppostyle, but after hours of T-mobile tech support, a factory reset, APN attempts, still no LTE or proper 3g even on my Find 7, even though I live in a strong 3g/4g area...only (HSPA) H and H+. Can anyone help?

Was briefly excited on the arrival of my US version from oppostyle, but after hours of T-mobile tech support, a factory reset, APN attempts, still no LTE or proper 3g even on my Find 7, even though I live in a strong 3g/4g area...only (HSPA) H and H+. Can anyone help?
Thank you

Hmm, those match my settings and I am getting LTE. Dumb question, but have you restarted? I noticed my phone can get kinda quirky when switching between APN's, or if the data gets turned off by another app for some dumb reason or another.
I have a feeling there is a little more tweaking to do to the modem from Oppo...

I get LTE (4G) with these setting just fine on TMO in Texas.... remember it will show 4G not LTE.

Have you confirmed that you actually have LTE in your area?
Remember that for years, T-Mobile and AT&T called HSPA+ "4G"

I was uunclear about H+, have just been looking up info....Was on Verizon, a GSM newbee here
However, I am seeing very slow speeds on HSPA+ and HSP...not even seeing much of a difference in speeds between the two on my device.
between them. Averaging 0.6 Mbps to 1.3 Mbps down, and 0.8 mbps to 1.3 Mbps up, even though T-mobile tech support claims I have excellent 4g coverage in my area. Is this most likely hardware?
Also, on my roadtrip yesterday to Medford, I was capping off at around 10 Mbps on LTE at the most, which seems a ,ittle slow for LTE.

Sometimes your coverage can be solid but the backhaul (connection between towers and the Internet) can be awful. AT&T's local reps even told me that the local LTE isn't going to be particularly good for a while until they upgrade the backhaul to the towers.
Your HSPA+ speeds seem low, but that's in comparison with my AT&T experiences. I might try doing a speedtest comparison of LTE between my Nexus 5 and my Find 7a if I can.
I was reading the pocketnow review and they had trouble getting the phone to work on AT&T and T-mobile in the US. Does this phone even support T-Mobile LTE bands? In most areas T-Mobile has their LTE on the AWS band.

It actually does support them...I was told there was 4g here but there isn't as of yet

Mine does get all of these (4G, H, H+, etc.) but the problem is most of the time it can't even get data connection.
GPRS Setting for LTE works for Me
I was having problems connecting to data,calls no problem (OPPO FIND 7 USA).
Anyway,the automatic APN settings weren't right for me,I had to manually set the APN Protocol setting to IPV4 (wasn't set,reading Not Set) & it finally connected to 4G LTE.
Here's the strange part:
The APN Name (On OPPO FIND 7,USA Model) is T-Mobile GPRS NOT T-Mobile LTE.
If I changed the name,it wouldn't connect to data at all.
From best I can tell via web search, GPRS is synonymous with 2G,however,I have 4G LTE when this APN Name is used.
I've seen others having a hard time connecting to the network & seems this bug arose in the latest update.
Anyway,my settings are identical to those in the pics in the OP EXCEPT the very 1st line,the APN Name.
Where I'm at right now is notorious for a weak signal due to building/equipment interference,however,I'm picking up an excellent signal (-90 to -80dBm / 53asu) on LTE:13
Have you tried to turn on LTE 4G by going in the dialer type *#*#4636#*#* phone information and set preferred network as LTE only ?

Yes.
As it is now,w/the APN Name as T-Mobile GPRS & in the hidden menu,changing the preferred network to LTE has no effect,it stays connected to LTE & everything below that which is available in my area.
I just left it as UNKNOWN.
I tried changing the APN Name to T-Mobile LTE & it immediately disconnects,regardless of any other changes in the hidden menus.
As the phone senses/sets-up Auto APN,the only apparent thing that is omitted is the APN Protocol setting,which by default on my phone & SIM Card registered Not Set.
Changing that value to IPV4 (from Not Set) is what made the difference.
Perhaps this quirk has something to do with 2G in my area having been replaced/upgraded to 4G & 4G LTE & the phone doesn't sense the difference/recognize the difference but in name only,but,accepts the 4G/LTE Connection.
Not knowing all things network/etc..,this seems like a possible explanation.
All I know is that I have an excellent connection & fast speeds w/browsing/etc.....
I don't care what the phone calls it,or sees it as,success is success.
I've seen stranger things than this........
I have since replaced my SIM CARD & had no problems connecting to T-MOBILE's 4G LTE,no modification of the APN was needed.
However,this is while flashed to CYANOGENMOD 11 nightlies,have no idea if the previous issues would pop-up if running the stock COLOR 1.2.4i O/S.
I have had issues with T-mobile LTE. Played around with all the settings. Deleted the APN and created a new one, etc. It works now, but I didn't do anything special, it started working randomly a day or 2 later
Strangely enough I'm having the same problem getting 3g with Virgin (EE/TMobile) in the UK
It can take a while for LTE to provision after setting up the APN. Set it and let it try for about an hour.
APN
The APN setting should have no effect on this.
You have 2 different fields when you type *#*#4636#*#*, gsm service and gprs service. If gsm service does not show "in service", you can use any APN in the world and it still won't work.
I have seen threads about people locking LTE band 4, and that's not a problem for me in the Dallas area, as mine is usually always defaulted to that band. But I see posts of pictures with people getting 50 to 90 Mbps downloads on t-mobile note 3. Only thing I can notice is different on the debug status menu (using service mode) is the BW frequency on theirs is showing 20 mhz (<---I may be wrong when u day mhz, but it is showing 20) and mine reads 15. I get consistently 16-18, and my top is 21. How can I adjust the BW frequency? How can I tap into the truly fast speed? I have the right band selected, and I'm in a proper market... Can anyone help with this?
Just for the sake of wasted replies, I am on T-Mobile Note 3, SM-N900T, can access service mode, I can use TW room or AOSP, so whichever one I need to be on I can switch, and I have searched threads and Google, but can only find help on accessing service mode and pictures of blazing speeds, but no real help. Thanks in advance, and happy hunting ha!

You cannot change that. It is the Band with that tmobile has put iut in your area. 15×15 im guessing by what you said. And you do indeed get better speeds on 20×20.
So I can force the band (if need be) but the bandwidth frequency is sent to my device, not chosen by me correct?

Wrong place to post this question, but I hope you get answers.
Correct. You can not change bandwidth unless you guve it to tmobile
Technically you can change the frequency band your phone is locked to but if it's not in your area you will get no service.
Sanding phones have a menu that you can go into and change which bands your lte is locked to.
On a tw stock rom
You have to take out the sim card. Boot the phone up and goto the dial screen

You can check your lte band

Thanks for the reply, but I can already change the LTE band, I want to change the actual bandwidth frequency from 15 Mhz to 20...

you'd have to change the tower's yourself then haha. its impossible to do that unless there was a way to do that and if that tower itself actually supported those BW freq's in the first place.
Not sure but I get this in Richardson
Can you get in service mode and screen cap your info screen? Also, did you change anything?
