hello,
can you guys pick up different signal carrier in your hd7?
i am using T-mobile HD7 and the signal is not stable in my place (i have few drop calls). the Verizon signal is much better and i can pick it up from this menu >start>setting>cellular>network selection>
I can force the phone using Verizon, but the problem is after the choosing, the cellphone did not show any signal bars. <most likely phone can not register in the network>. it is wired. any ideas?
tmobile phones cannot use cdma networks, different radios, different technologies.
can a AT&T or cellular network be used in this phone? t-mobile signal is so terrible in my place.

yes you can use at&t if you sim unlock your phone. T-mobile might do it for you or you can pay one of the web based companies that do it.
You won't have 3g though.
Why did you get a t-mobile phone if you don't have t-mobile reception???
nope. AT&T work off different network signal than the others do so you won't have much luck. and i'm not sure if the HD7 from t-mobile supports the band (network signal) that AT&T uses. so you could try but i highly doubt it.
t-mobile signal is not good in my place.
to be honest with you, I hate AT&T and verizon.
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.
I bought an unlocked Sony Ericsson Xperia Play R800i from Amazon to use with a Straight Talk sims card; however, I'm unable to connect to 3G. The phone only shows an Edge connection. Straight Talk specifies that the phone must operate in 850 and 1900 MHz bands. Here's what the Amazon page says about my phone:
This phone can be paired with 800/850/1800/1900 MHz UMTS/HSPA 3G networks in the United States (as well as 900/2100 MHz 3G networks found around the world, including in Europe and Asia). In areas not served by a 3G network, you'll continue to receive 2G data service via the EDGE network (depending on network compatibility).
I might be wrong, but doesn't that mean it operates under Straight Talks specifications?

i have the same issue but with my carrier offering 3G at 2100 Mhz which is Xperia Play supporting. When searching for carrier it shows me just 2G provider, non 3G. when WCDMA only selected, i lose signal. I am in coverage of 3G and my plan is supporting it.
Could it be hardware issue? i did factory reset but still having this issue. Connections just through EDGE, GPRS or Wifi

I purchased an R800at from Amazon, which, according to that thread, should be able to connect to 3G correctly.
I've unlocked the bootloader, and flashed CM7.2 onto it, and I'm still only getting an EDGE connection. It shows a second connection under the "Network Operators" menu in the mobile settings, which, when I ran the stock ROM, was listed as "3G" but it always defaulted to the "2G" listing.
I live near a large city, and have gotten 3G on other carriers, and even 4G on a friends T-Mobile phone. I think I'm running the T-Mobile based SIM card, because the AT&T APN settings don't work with it, and the SIM came with the T-Mobile settings, it's even labeled in my APN as "Straight Talk T-Mobile" but I still only get EDGE.
I don't know much about straight talk, but is your Sim a 3G one? I had this issue a while back where i could only connect to 2G networks but then went to my carrier's store, told them the problem and they ported my contacts and number to a 3G sim and its worked ever since.
It may also be worth trying to get the APN settings from your service provider to see if this solves the problem.
I have an unlocked R800at (AT&T) that I am using on T-Mobile. Now where I live it shows that people have already reported getting HSPA+ on unlocked AT&T phones.
I have all the correct APN settings, however I always get 2G (Edge). But if i got to:
Wireless Networks
Mobile Network
And select search, for me it will bring up T-Mobile 2G and T-Mobile 3G as options. I select the 3G and it will connet and I will get HSPA+ (download of up to 7mbps, 3-5 up) for anywhere from 30 seconds to 5 minutes, then it reverts back to 2G. Its not a huge deal for me as when I was on VZ I had edge like speeds, but to be honest if I can HSPA+ then i would like to have it but I cannot find a way to get it to stay on 3G. I have used 3G speed tweaks, trying different apn's... nothing. Anyone have any ideas or suggestions?

I'm not entirely sure. I bought it on ebay, it's listed as a T-Mobile SIM card. It was a standard size, that the seller cut to micro. I have to put it in an adapter to use it with the phone.

hi, i have the same problem. r880i, it works well on gsm, totally unstable under wcdma..the "funny"thing is that i can't make calls nor text when it gets no signal(with the yellow triangle at top left),but i have data connection(i can install apps from store,browser youtube facebook works ecc) and i get mm#6 error sometimes(the phone in not stolen or whatever lock). all working well when set to gsm; if set to wcdma/gsm, or wcdma only it does the above mentioned behavior. i've relocked bootloader and repaired with seus and am currently on stock 2.3.4.. any fix or know issues?
I just bought the tab 3 7" T217A from at&t and went to Mexico to use it in 3g but I don't get any data access.
The tab recognize the sim card company (telcel) and the APN values are correct, it's Sim unlocked I suppose.
Pretty much all carriers in the US are locked to their devices. However, that should not stop you from data connections unless the host carrier does not have data or the host carrier uses different frequencies for data. It is also possible you may have to use EDGE and not 3G for your data. My iPhone 3GS worked in Afghanistan on GSM but I was limited to EDGE as they had no 3G. Just a thought. You should go to a local cell phone store and ask about data on the T217a.
Caveat: I do not know the Mexican network nor the device you are using. My comments are just based off of assumptions.
Yes, you are right, I had few phones that appears in edge but can connect tod data but in this case the signal icon appears just the bars but no E icon or roaming.
I think I'll go to a store to check it
Issue:
Phone will not stay locked on LTE in Global or LTE/UMTS/GSM mode. When in Global or LTE/UMTS/GSM mode and LTE does connect, it's momentarily and when trying to run a speed test or open a webpage, it quickly disconnects and connects to HSDPA. If switched to LTE/CDMA signal locks in great and data speeds are great however voice services are not available. Any thoughts or advice is welcomed. Thanks ahead of time!

What band LTE are you connecting to? I found that here on band 2, I will connect at first, but then it switches back to edge. Seems fine in a band 4 LTE area though.

I'm in the Raleigh NC area. According to LTE Discovery i'm using Band 4. and I also experience the same. A brief connection while in global or LTE/UMTS/GSM mode then it falls back to HSPA.

I haven't found LTE Discovery to report the band correctly, at least in my case. It would say I'm on band 4 on my Moto X, but when using a band 4 only device I would only get Edge, but when I go in a confirmed band 4 area it works fine. From what I've found, most 2G > LTE sites were converted to band 2 LTE. Although since you get HSPA the chances of it actually being on band 4 are higher.
I'm fairly certain this is a Band 4 area. The latest T-Mobile maps are pretty good about pointing out Band 2 areas. I've since sold the phone and acquired a iPhone 6 Plus which I'm looking to sell to replace it with an international G4 or T-Mobile G4. I was pretty impressed with that phone. If I had to rank my favorites, it's number 2. Nexus 5 is still king of the hill for me. There wasn't a better phone out when it was release for a better price.
did you ever figure this out? samething is happening to me
Unfortunately I didn't. I sold it and bought one for T-Mobile...... Which I just sold about 3 hours ago.
So I tested it out again, and in a band 2 area when I boot up my phone with a T-Mobile SIM, I get LTE for several seconds then it cuts back over to 2G.
Now that there is a new software update for the G4, I wonder if this is anymore reliable. Anyone who took the OTA update in the past few days, can you let us know if it's any better?

Been there, done that...wanted to switch over to T-Mobile, but unfortunately, the VS986 only works with two of their three LTE bands, as you know, and it seems everywhere I went, they were using the one the phone doesn't receive (I'm in southern California, for what it's worth, but tested it on a freeway run up the I-5 to the central part of the state - only got 4G-LTE in a few places). Wound up going back to Verizon
I'm getting the exact same results in Burlington, VT (T-Mobile band 2 market). I first have to manually select T-Mobile (defaults to roaming on AT&T HSPA+) then LTE works for less than a minute (LTE Discovery says band 4) and then I lose signal when I get signal again, I only have edge. It does this constantly and is really annoying.
Aww, bummer. I was thinking about switching to T-Mobile, but looks like that is not a viable option? So no one has been able to successfully use the phone on T-Mobile, even after enabling bands 2 and 4 only?
This whole plethora of LTE bands, where each provider does its own crap is such a mess, is just serves to lock in customers, since switching phones is expensive. Government should mandate that all phones can work on all US LTE bands, the technology exists.
I am on the same boat. Everything works on my VS986 on t-mobile network. but I cannot get the LTE to work properly. LTE discovery shows band 4 (not sure if correct though)

My VRZ LG G4 shows that it has Band 2, 4, 5, and 13. I tried enabling 2 & 4 only, 4 only, 2 only, 2&4&13 only but with no success.
What is interesting is I am coming from VRZ LG G3 and LTE was just fine and never had an issue.
I looked at the VRZ LG G3 LTE bands and I see Band 3,4, and 13 enabled. It did not even have band 2.

I think since someone reported before that this used to work the G3, it sounds like a bug to me. I guess we can hope and pray that this will work in future releases, but there is no guarantee of course. Not sure what complaining to Verizon will do, since they are probably not very interested in you using T-Mobile. Of course, you can always wrap the complaint into something like you are using the phone in a different country on vacation and it doesn't work. Maybe a complaint to the FTC could work too, since it sounds like Verizon is required to have their phones unlocked for use on other networks based on some settlement.

I am tempted to try the guide in here to add more LTE bands:
http://forum.xda-developers.com/g4/general/guide-enabling-lte-bands-t3137818
While some testers said the LTE bands are limited by hardware others reported some success modifying the software. Any thoughts?
