I've got an unlocked AT&T Galaxy SIII, and I only get Edge for my data connection. Do I need to flash a T-Mobile radio? APN settings look okay, as far as I can see.
Also, can I flash a T-Mobile ROM and use Wifi calling, or is that asking too much?
I searched and couldn't find anyone asking these questions in the Q&A forum....
there are already like 3 threads below this one concerning the 3g/4g topic on a att sg3 working on tmobile. No it will not work because att sg3 does not support the aws tmobile frequencies. you will only be able to get edge. NOW if it were a tmobile sg3 on att then it would work.
All the threads I could find in this form on my search went the other way: T-Mo phone on AT&T.
Does anyone actually know whether a T-Mobile modem on an AT&T phone would work or not? I looked at the main board in my phone, and it's labelled with both SGH-I747 and SGH-T999, which makes me think the internals are fully identical.
I'd like to know this too! I also have an AT&T Galaxy SIII and was seriously considering moving to T-Mobile because of the new unlimited data plan they were going to start offering on 9/5. I had also looked through this forum, and could only find questions of the situation the other way around, T-Mob GSIII phone on AT&T network.
Basically, was wondering:
- is there a hardware limitation that APN settings and/or installing a new modem will not get me good data speeds?
- would I need to burn a new modem?
- I'm assuming at minimum I'd need new APN settings, and am assuming T-Mobile would be able to help with that. Right?
Thanks, really interested in being able to do this!

Hey oblib - looks like there's an unfortunate hardware limitation we won't be able to get around: http://forum.xda-developers.com/showthread.php?t=1771021

Where did you see that the boards were labelled the same?
AFAIK, the radio's are different and flashing a T-mobile modem could possibly brick your device. It would be much easier to buy a T999 and use it on T-Mobile (it'll even work on AT&T 3G if you want to switch back, no LTE though).
The SoCs are different. Flashing a T-Mobile modem will not give you T-Mobile HSPA.
Looks like I didn't take any pictures of that side of the phone while I had it open, and I'm not eager to pop it open again. It definitely listed both models on the PCB. If I'm remembering correctly, it's on the same side as the SIM and SD card slots, so it's just matter of removing the back plate to see it, no more disassembly than that.

Do you have part numbers for the two? According to wikipedia, they are the same Snapdragon S4 MSM8960. I just find it hard to believe that they would be different, though if they have the same pinout, that would explain the markings on my PCB.
This has been rehashed countless times. They are not the same phone. If the phones were the same, people would not be in here asking if they were the same. The MSM8960 comes in more than one flavor, with different modem parts. Yes, the CPU's are the same, but the MODEMS ARE DIFFERENT. It is an S4 Qualcomm part that comes in many different configurations. Instead of just reading until you get to some information that reinforces your preconceived notion, try reading a little further into the links at the bottom of the page and elsewhere. Seriously, if you really really don't think that Qualcomm would make different versions of the same chip, or configure them differently for the hundreds of different customer requirements, then fine, don't believe me, but it defies logic. Sorry about being an ass.

The T-Mobile version uses an MSM8260a. This SoC is the Krait with an adreno 225 GPU and no LTE. The MSM8960 has all three.

Thanks for the useful response. For those looking for even more detail, here's a link: http://www.qualcomm.com/sites/default/files/common/snapdragon-specs-06.07.12.pdf
According to that the MSM8960 (chip in I747?) has a "World Mode" modem, while the MSM8260a has a UMTS modem.
Edit: Ah, and I see both of you have answered this question before, which I would have found if I searched on MSM8260a. The threads have been dead for over a week, so I'm not surprised I missed them, but thanks for answering the same questions again.
T-Mobile HSPA not support i747 right now.

T-Mobile uses a frequency for their 3g and 4g network that only T-Mobile branded phones have. Any other GSM phone will never get 3g or 4g on T-Mobile network unless it supports the T-Mobile band, which I believe is 1700MHz. It's limited by hardware. Nothing you can do to the phone will give you the 3g/4g you have to have a T-Mobile branded device.

Not completely true. Since The Galaxy SII and the Galaxy Note (AT&T) have software radios, you can flash a radio from the TMO GSII and get 4G on TMO. I was running mine and many customers of mine like that for months until i switched phones.

It works fine for me, the area i'm in does not support 4G on the 1900MHz frequency so I can definitely confirm my stock non-rooted AT&T i747 galaxy SIII is working on T-Mobile USA's 4G data network. I've uploaded a video to youtube of how to get this to work, should also work for the AT&T i317 note II as well. I can't post links on here I guess so just type my youtube username and search my videos.

This is NOT TRUE, please be careful when making such "absolute" statements -- I just got a ATT i747 from craigslist, and it DOES work with the $30 Walmart plan - on 4G and LTE (depending on location).
The TRUE ANSWER IS -- IT DEPENDS -- if you live in an area that was recently upgraded to LTE (in my area was 02/13), you can get LTE/4G since t-mobile added support for it on 700 MHz (band 4) AWS (unverified - source: youtube video named "Tmobile 4G on att i747 gs3 data fix". Sorry I am not allowed to post web-links yet).
Anyway, I DO get 4G/LTE, I guess I was lucky

I am looking to get a phone a bit nice than my HTC vivid. Someone at my local craigslist is selling the LG Nitro HD in "brand new condition except speaker doesnt work" with an extended batt + cover.
I can probably get it for about $140 or so. Best deal I'm finding on anything that will work with AT/T and tmobile.
So the question is, is it easy to repair the speaker? I see that once you take off the back you can see the speaker. Is it simple as pulling out the old one and putting in a new one, or is soldering and what not required? Thanks in advance
Just read that you can not use 3g/4g from Tmobile on unlocked AT&T LG Nitro HD = nevermind, not interested. It was such a sexy looking phone, too...
The speaker comes as part of an assembly and looks like this: http://dl.xda-developers.com/attach...840c00b004d404/50beaea0/1/0/1/9/3/6/7/4th.jpg . It's extremely easy to replace (only remove 3 screws under the battery cover).
You can see this guy remove it here: http://www.youtube.com/watch?feature=player_detailpage&v=5oPGrgCdOoA#t=41s

Yeah, almost no AT&T phones will work with T-Mobile 3G. For T-Mobile, I'd definitely get a Nexus 4.

I actually installed the custom rom Virtuous Inquisition on my HTC Vivid (AT&T and EVERYONE says it will not work) and I get 3g and sometimes HSPA on it. Was hoping maybe case was similar here but guess not
So sad because Nitro is a super sexy phone (I think at least)
Actually I'm wondering if it's because Tmobile has rolled out the new radios or whatever it is that makes some phones compatible in my area... I keep hearing about that... "Flipping the network" or whatever... Anyway to test that thoery? because that would mean many phones should be compatible, right?

The Vivid (and several other LTE devices on AT&T's network) support LTE on the AWS band, which is the same band that T-Mobile's 3G network runs on. Although nearly all of AT&T's LTE network is on the 700MHz band, they are beginning to roll out LTE on the AWS band as well. That means the Vivid has an antenna in it tuned for AWS. It's possible that internally it is wired such that it can also use 3G data on the same band (since it already has the antenna), but is "disabled" through software (since 3G on AWS is useless for AT&T's own newtork). A custom ROM might be able to override that.
I'm just guessing here though, so don't take this as fact.
However, if I am correct, the same method wouldn't work for the Nitro HD because the Nitro HD does not support AWS band for LTE. As far as I know it's the only LTE device on AT&T's network that supports 700MHz LTE but not AWS LTE.

I know everything there is to know about computers... But not a whole lot about phones at all lol. Taking your word on this (your use of terminology has me convinced) and assuming that it will not work, ever. Thanks
Why OP sees T-Mobile 3G on an AT&T phone is because TMo is refarming its 1900MHz spectrum and deploying [email protected] in some markets. This is mostly for iphone but many other phones also benefit from that, including P930 here.
I have a Galaxy S3 purchased in the UK that is compatible with Rogers, Fido, and Bell in Canada, however i tried to put a mobilicity SIM in and it wont work. They told me at the store that its because of the radio frequency that my phone carries. Ive done research into this and ive found that it can be changed, however instructions to do this are vague and unclear. Can someone please help me with this?
If the phone doesn't have the appropriate radio to support the AWS band (1700MHz), software won't allow you to do it. Given from everything I can see on the GT-i9300 specs (which is the UK model), you will not be able to use this on Wind or Mobilicity at all.
Yea it doesn't work on Wind or Mobilicity.
Sorry to bump up an old thread, but is it possible to flash the LTE Version of this phone so the i747 with a WIND Mobile Baseband and have it working on wind?
Nope. They are different phones. My earlier post applies here too.

Why Samsung Galaxy S III always stuck with the Edge network
After bit of research I have found the solution to the problem.
The information about this is very hard to find. So I have compiled useful information into this post. I am sorry guys I have given basic instructions only and I guess you are comfortable with these terms. And it is very late and I am writing this so that other can save time doing researching this stuff.
First of all the issues is to do with the carrier and the handset's operational frequency.
Use following links to get more information about T-Mobile frequency ranges ( I can't post any links in the reply :crying)
Checkout T-Mobile site for frequency ranges.
My phone spec is as follows;
Model: GT - I9305
Android Version: 4.1.2
Kernel Version: 3.0.31-1153417
For Samsung Galaxy S III;
To get what frequency the phone is currently using type the service code; *#0011#
My Samsung Galaxy S III uses; PCS 1900
This means my phone currently uses UMTS 1900 frequency range.
Now the cool part is you can access your Samsung phone's hidden frequency settings by service code; *#1973286403#
But the result screen is different in each Samsung model.
My screen shows following. It is not the same for all Samsung models. So you have to play around a bit with those menus.
[1]UMTS
[2]CDMA
[3]LTE
[4]SIM
[run EFS SYNC()]
Go to UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION
Under that section by default the value "Automatic(*)" has to be selected.
If you need to check what WCDMA frequency band phone is using navigate to
UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION > WCDMA Band Preference
Under that section you can select what frequency to use if you know your carrier frequency.
But in my case the phone supports 850 MHz, 900MHz, 1800MHZ, 1900MHz, and IMT 2000 (which I think 3G)
Unfortunately T-mobile uses 1700MHz and 2100MHz band for their 4G HSPA+ network which will not fall into my phone's supported frequencies.
So this is the reason behind your phone not picking up the 3G or 4G signals (in T-Mobile’s case 3G will show up as 4G).
To resolve this you can install a custom rom with modified antenna frequency. But I would warn about that because that could seriously damage you antenna and drain battery etc..
I have some more information on this but I will keep them post as I get time.
Please note I am software developer myself not a network engineer. So I would appreciate if anyone with enough experience to add more comments on the network aspect of this issue.
Thanks.

Thanks for the reply by the way. No my IMEI is not zeroed out.
Ok, well first, if you have the I9300/I9305, you are in the wrong forum. This is for the SGH-T999 only.
And second. I'm not sure what you mean by installing a rom with modified frequencies. A rom does not determine this, the modem does. And no rom should ever include a modem.
But you are correct on why you cannot get 4g. And fyi, the international model and the US models are very different devices. Do not flash anything from this forum, only the international forum or you will hard brick the phone.

I am really sorry for posting stuff in the wrong forum.
One thing to clarify you can install a customized ROM doesn't solve the issue completely. I agree with you. But ROM can have firmware patch of some sort that will enable the modem to be tweaked. Or you can install something which changes your antenna settings so that it can receive required signal. To address this issue I am looking in to firmware API a bit, I haven't tried this before. If I can write some code to teak I will keep it posted..
Thanks

It seems like Pakistan uses 1800mhz for the LTE. In terms of At&t and Europeans G3, they don't have the same LTE bands.
At&t does NOT use 1800 only the European one has it.
So since Pakistan uses the same bands as the Europe, then you'll have to pick which between having LTE in the U.S. or LTE in Pakistan.
Both phones will work for 3g though.
Hope that helps!

I'm not concerned about LTE in Pakistan since as of now Pakistan doesn't have LTE networks setup . Also LTE in US is important for me. In Pakistan I only want to be able to use my phone i.e call/text.
I have two more questions:
1. Would I be able to use an AT&T device with Pakistani/European carriers without unlocking it, if I buy them without contract.
2. Can I use the korean G3 (f400) for ATT LTE? I've read it somewhere that some people have got it working but I want to be sure.

Since you not concerned with LTE in Pakistan, that makes it a little easier.
1. You can buy an At&t phone and get it unlocked. If you buy it outright (full cost), at&t might provide you with the unlock code, I'm not positive about that.
If you are still on a contracted type plan and you buy it subsidized with a 2 year contract then you can also just buy an unlock code for $3 and get it unlocked. I'm not affiliated with this website but I have seen others use it (www(dot)gsmzambia(dot)com/) and has success. I personally used cellunlocker and it took 24 hours to get my code and was about $8. (http://forum.xda-developers.com/showthread.php?t=2780536&page=2)
2. Yes you can use a Korean G3 as it has the correct LTE bands and will works for At&t LTE.
This is only if you're interested in Roms/Modding/Qi Wireless charging
If you plan on buying your phone outright from at&t, I would highly recommend getting a t-mobile phone if you like to flash roms, use QI wireless charging. T-mobile has their bootloader unlocked so its more rom friendly. Also it uses the Qi-wireless standard vs PMA which is much more widely used than At&t's PMA (powermat)
T-mobiles phone works for At&t and has all the bands except for band 5 which at&t isn't using.

Was everything hassle-free, like making calls, or getting good signals?
I've searched on amazon and this is what I found:
http://www.amazon.com/LG-LG-F400-Me...8&qid=1407384558&sr=8-1&keywords=lg+g3+korean
It says 4G won't work in US.

What about the bloatware and the Korean language. I really hate bloatware!
Also please can you link me the site where you bought it from and also check the F400 version on amazon and let me know if that is the correct one.
Thank you!!!

90% of the bloatware is uninstallable. The Korean language on the dialer, and in the theming app is what made me get rid of it for the att version. I also didn't like how it handled USA phone numbers via text messages. It always sent and received duplicate text messages

I am not talking about a tmobile phone on att. I am talking about the signal that the f400 (Korean model) would get on att and tmobile. You need to 're read my previous comments

I bought the ATT version and I love it so far! However my only issue is the charging time on this beast. It takes a lot of time to charge, especially if I'm gaming on the device while it charges.
