Or even flash it in At&T SG3. Samsung said the hardware are the same and have all the frequencies. i believe it might not be advertised this way from the carriers. Just thinking out loud.
Sorry i posted in the wrong section. Admin please move to Q&A
sorry again
Eh, I dont think so. Not at first anyway... after some hackery it might be possible.
The US versions are all the same.
The International version is very different.
It will never work.
I have yet to get 5 bars on my SGS3. Kinda odd.
Not a good idea as someone already stated they're different. I did that once by accident with the original galaxy s. Flashed the canadian firmware for the US version of the phone and ended up bricking it. Not even a jig bought it back to life.
It should work with the at&t and t-mobile sgs3 just like with the skyrocket and t-mobile's sgs2

The Skyrocket forums.. the AT&T Note also works because it also has the same SoC. The international version will never work with AWS though.

... if this is true, I'm getting an AT&T S3 at retail and then flash the radio to T-Mobile.
Chances are I won't resist temptation and get the t-mobile one anyway

It hasn't been tested yet on the S3. And while it works on the Note, it is far from optimal. I have not read since the early stages but it would freeze and get awful battery life on T-Mobile.

The US [GSM] models, ok. The international model, 100% no.
And as I understood, the T-Mobile version is pentaband out of the box (it will get AT&T 3G/4G 1900 MHz) because T-Mobile is moving to that frequency. So if anything, get the T-Mobile one and use it on AT&T if you don't care about LTE.

The Note had abysmal battery life from what I read. Just wait for someone to do it (they will) so you don't have to possibly return whichever one you buy.

Well the At&T Galaxy Note is what inspired me to think it might be doable!! The At&T Note i have is working fine with Simple Mobile and picking up 4g all the way. the battery sucks anyways even with the At&T modem. Also, you guys should note that stationed in Kuwait and im using the At&T Note with T-mobile modem overseas and still working great. Yes i have 3G as they dont have 4G here. they funny thing is that i still shows 4G and run about 19Mbps in most places.
I can get the international SGIII in Kuwait for $250 16G unlocked (NICE RIGHT?) but when im home i use the Simple mobile network(T-mobile).
you can call it greed but i want to have 2GB RAM, LTE, T-mobile 4G and the ablity to use every network in the world
I hope someone can make this happen
The reason it worked with the AT&T Note is because the T-Mobile S2 used the same SoC (Snapdragons S3). The US Galaxy S3's have Snapdragon S4's, the International has an Exynos 4412. The SoC's (CPU, RAM, Radios, DAC) are COMPLETELY different. It will NOT work. It's not software magic that got the Note to work. It's the fact that it supported the 1700 MHz frequency. The Exynos SoC's radio doesn't. You'll end up bricking the phone and requiring a JTAG.

Can you please confirm this, if I get the T-mobile version, and get it unlocked and use my existing AT&T sim on it, it will get 3G/4G speeds?. Would the international version also not give the same?. 4G speeds with AT&T?.

I'm using the i9300 (International) on Straight Talk AT&T, which runs on AT&T's base network, and I get full HSPA+ (of course, no LTE). The i9300 runs on AT&T's bands, so if you used it on T-Mobile you'd only get EDGE (for now, because they're moving their network onto the same frequency as AT&T). If the T-Mobile version is indeed pentaband as I suspect, then unlocking it and using it on AT&T will give you the same data speeds as using the international version on AT&T.
Hello fellow Canadian GSIII owners: please see below and note which forum you should be looking in for ROMs for your devices:
AT&T forum: SGH-I747 (AT&T, Rogers, Bell, Telus and SaskTel)
T-Mobile forum: SGH-T999 (T-Mobile, Wind, Mobilicity and Videotron)
Sprint forum: SPH-L710 (Sprint only)
Verizon forum: SGH-I535 (Verizon only)
Developers, please put carrier support in the title of your threads. Thank you!
---------------------------------------
Hello XDA,
Can we please get an android development forum for Rogers, Bell, Telus and Wind? Rogers/Bell/Telus phones are SGH-I747M and the Wind version is the SGH-T999, but they all have different basebands and stock ROMs. Trying to put Canadian threads in AT&T and Sprint forums will result in a big mess.
Alternatively, instead of separating by carrier, separate by model number. Keep all the I747 development threads in one forum and T999 threads in another. Then people can put the carrier into the title of the post.
Just something to think about.
Thanks!
I agree. But AFAIK, the Wind/Mobilicity/Videotron S3 is the same as T-Mobile's, not Sprint's.

historically Rogers and AT&T have been interchangeable in almost every aspect on all the devices they shared. Rogers uses the exact same frequencies as AT&T, and the devices are the same aside from some minor differences in bloat, lte toggle, and native wifi tether
What about the Telus, does that fall under at&t also?
Thanks
I agree very hard to follow on what is for which phone, not going to take any chances until things are a little more clear. Still have the old S1 to mess with.

AT&T, Rogers, Bell and Telus have the same phone, the SGH-I747. But just because it's the same hardware does not mean it's the same software. It may or may not have different basebands and certainly has different carrier customizations. As Pirateghost mentioned, AT&T removes some features in its ROM (software), the most important being, at least for me, the ability to tether. So if you flash a rooted AT&T ROM on your Canadian device, it will most likely work but you will lose features(!) That's why we need to be very clear about what carrier each ROM is for. Furthermore, if you flash the wrong baseband (i.e. flash a Rogers baseband on a Bell phone), your phone may not work as a phone or it may connect to the wrong network and you will be charged roaming fees. At the moment, I can see that AT&T has a different baseband version from Bell, but Rogers and Bell seem to have the same baseband version. Are they interchangeable? I have no idea. Anyway, it's better not to mix these things up. That's why separate forums are a great idea.
As a SaskTel customer coming from the international i9000, these forums are very confusing and not very organized. I would definitely support more organization.
I guarantee that you won't roam on the other carrier if you flash the wrong baseband (Telus/Bell/Rogers). They don't have roaming agreements in place to allow that. That's why you won't get service with Rogers in some areas where Bell does have service.

That is how it was with the i9000. If I flashed the wrong baseband (for example, a US modem that did not support 850 band), I would just have no reception when I left the city.
Sasktel, Bell, Rogers, Telus all have the AT&T version with tethering left in.

Except this time around, it seems that there is a slight difference between the two in terms of software, and enough so that I've read posts of people having issues when using at&t based stuff on their rogers phones.

So is it safe to say that you can flash the Stock Rom or Custom ROMs for T-Mobile T999 on Wind Mobile's T999V. And at most you lose Roaming and/or a few features?
I already see that there is one or two ROMs that are confirmed for multiple carriers.
A dedicated Canadian Forum is a great idea! There is so much information floating around out there with the multiple variations of the sgs3.

As a Rogers user (and relatively new to Android) it freaks the hell out of me to flash custom ROMs based on the AT&T version, because I'm sure I *will* lose tethering and the ability to turn off LTE.
That's the stupid thing - it'd be rather simple to have subforums dedicated to the canadian devices, because the software is different (not only the bloatware, but apparently some more stuff too) and the baseband is also different, which could lead to problems down the line, no?

If a rom is done the right way you won't lose any functionality. You can't honestly believe that at&t users don't want those features. I prefer to build all my roms from a rogers base for the simple reason that it is less work for that functionality.
PS. Any rom dev should know better than to force a modem/radio/baseband change on their users.

That might be true but if you check your firmware versions, they aren't the same as AT&T's.
Also, I have flashed most of the international radio's on my older I9100 and never had a problem in Canada or US when travelling. They may not be customized for that country but they do work.
I PMd one of the mods with a link to this thread. There seems to be interest in a forum for Canadian carriers, so let's see if we can make it happen.
By the way thanks to everyone chiming in with their two cents. I am not a developer, and although I've been around xda a while, it was always as a user. I''ve written a guide or two on how to root and flash devices, but it was always based on other people's work. So I am learning all this as I go along.
I come from the desire z/g2 forums. G2 is t mobile, The desire z is run on multiple networks globally. Baseband are set by the phone, not the radio (I think that is the same thing as a modern?). On my Desire z running on Rogers, I flashed T-Mobile radios and international radios which worked on Rogers no problem.
Features of a rom are determined by the dev, if you don't like something, flash something else or restore your nandroid backup. Read the op and ask the dev if you are unsure about any features on a Rom.
I would think the only models that should be separated in forums are the international version, totally different processor and maybe Verizon cdma. From a sheer volume of users standpoint, further division is warranted. You think this is bad, wait until Verizon and At&t widely launch, this current setup will be complete chaos.

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!

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.

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 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.

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 just got this baby unlocked, FINALLY, and was wondering if I need to flash any modem/radio to get the best possible performance.Thank you all for your awesomeness!
I don't think there's any specific modem that would work best under those circumstances, particularly as modem performance seems to be location-dependent; if you're curious, you could just cycle through all of the available modems and see what works best for you in your area.
I believe you're in the wrong forum. This is the forum for the i747 Galaxy S III.
If you're on T-mobile, you'd have the T999, which is in a separate forum over here
The differences are the T999 doesn't have an LTE transceiver and the radio uses the AWS band rather than the PCS band for HSPA.

...which he unlocked, and now wants to use on the T-Mobile network. This does not mean he has a T-Mobile device.
I have a T-Mo Galaxy S4 that was SIM unlocked through unlockerDotnet.
I've heard that the T-Mo S4 is better than AT&T for a variety of reasons, but more importantly that it picks up all of T-Mobiles HSPA+ along with AT&T's network. So in theory, having it sim unlocked, I could fully utilize t-mobile's service and at&t's service to their full potential. Can anyone confirm this?
Reason I ask was I was speaking with a TMO rep once and he said the international unlocked version wouldn't pick up on the full spectrum of TMO frequencies, but it should be fine with AT&T. Ideally I want to get into a situation where I have the option to jump between the two through their full spectrum, or any mvno's that use their towers as well.
Thanks for the clarification! :laugh:
Details and specifics appreciated!
You can enable tmo AWS bands on AT&T S4. 2 phones are the same, basically the tmo version has the extra bands enable out of the box.

Thanks for the heads up :good:
So there wouldn't be any disadvantage to running the sim unlocked TMO S4 on ATT? I'd still pick up on all their 3g/4g/lte frequencies?
Much appreciated my friend
It will work its full potential on AT&T network if that what you want it to do.

Wait a minute... The ATT version has the tmobile bands too? I thought it was missing two of them.

I got another reply on a different forum that said
"T-Mobile's phone will work on both AT&T and T-Mobile however im not sure if the 4g LTE will work on AT&T's Network but either way you will only be able to use one or the other at any one time."
So, just to clarify, or rephrase rather, will 4G LTE work on ATT's network with the sim-unlocked TMO S4, or would it be beneficial to go with the ATT S4 and open up the TMO bands?
Sorry to beat the dead horse, just want to try and verify HSPA+ and both Tmo LTE and Att LTE will work with my setup, or if I should switch to ATT or International Unlocked version.
Again, many thanks for clearing this up!

K. Can anyone help me out with that last question that knows LTE tech fairly well? I read a bit about frequencies here and from what I can tell it seems like the LTE frequencies are 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz pending which geographic market you are in, but I'm not sure if there's anything else hidden in regards to carriers have specific LTE frequencies, and if so if any that a TMO sim unlocked S4 doesn't have.
In the end, i'm 90% going to be on TMO or a MVNO, but on the slight chance (or if i'm working around the country in a very rural area) I may want to switch to ATT and possibly their new prepaid service they're going to announce. Anyways, thanks again
My unlocked TMO S4 works perfectly on ATT LTE, doing it right now and have been for the last few weeks. That's why I bought it also was to hop between carriers.
While you can get the ATT S4 to work with TMO it's more difficult and not ready to go out of the box. I tried that and ended up just returning the ATT one.

T-mobile just dropped the price of their S4. There's no reason to get the ATT one but in case you get one and want an easy way to unlock the extra bands, follow this thread: http://forum.xda-developers.com/showthread.php?t=2324667

I have a T-Mobile variant s4 unlocked using it on AT&T network and just did my first speed test and......was very disappointed!
