Hello everybody, I am currently planning on coming to Tmobile from Att and I have a unlocked Samsung Galaxy S3 from ATT. I know it will work in terms of service, but my question is when I come to flash roms, would I flash them from the Tmobile section of XDA? Or the ATT section of XDA?
The phone originally being ATT with Tmobile Sim card was really throwing me off and I didn't want to do any thing stupid.
Thank you so much for your time.

Ok got it, thank you.
So it doesn't matter that my carrier will be Tmobile, I should still use Att threads and not have a problem?:good:

After inserting a Tmobile sim card into your UNLOCKED phone you will be able to flash
any of the roms here in the Tmobile thread as well as in the AT&T thread.
If you flash a AT&T rom the only thing you need to do to make it work properly is to
change the APN (Access Point settings) in the phone to be "T-Mobile US".
The phone can do that automatically by going into:
Settings>more settings>mobile networks>Network operators>Select automatically and select "select automatically"
and it will find that you have a Tmobile sim and it will change the apn to reflect that.
The phone will work just fine either way, however there is one main difference between
the roms found in the AT&T thread and this Tmobile thread.
The difference is when using Tmobile roms which are not ported from other carriers you
will have built-in wifi calling as an option when using the Tmobile roms.
Other than that you will not notice much of any difference at all.
Good Luck!
I bought a new SS S3 and ordered it for Tmobil network, but instead recieved a ATT phone...
SGH-I747
Everything works fine, and its not unlocked that I know of, but the whole reason I bought the phone was to use the wifi calling option of T-mobil, this att phone doesnt have that option.
Am I screwed? Should I send it back for a t-mobil phone or is there a simple way to update this phone to T-mobil and get the option of wifi calling from T-mobil.?

Hey robomas1. Would you be interested in trading your AT&T s3 for a brand new T-Mobile s3? I have a similar situation as yourself and got a T-Mobile version galaxy s3 but I wanted an AT&T phone as that's what carrier I use.
Let me know. Thanks.

When you are flashing any custom roms after you get your Tmobile sim chip you should flash the
Tmobile Touchwiz Jellybean 4.1.2 custom roms for the very best results.
If you do flash an AT&T cwm/twrp flashable custom rom you will find that even though the phone will
work fine you will loose the free Wifi calling feature in the phone if it's not flashed with a tmobile rom.
Flashing the official Odin flash Tmobile firmware on an AT&T phone even if it's unlocked and rooted will
cause the phone not to be able to make or receive any phone calls.
The reason for this is that all the official Tmobile Samsung Odin flash firmware contain a modem/radio image which
is not compatible with an AT&T phone even if it's unlocked and rooted but none of the Tmobile or AT&T CWM/TWRP
flashable stock or custom roms contain the modem/radio image file which means you can flash them without any issues.
Good luck!

It should go without saying but be very wary of someone who registered an account just to try to trade phones... There's a reason there's a big Swappa logo up above the site navigation bar...

Hi, I have a brand new AT&T S3 and need a T-Mobile S3.
So you still have the T-Mobile Phone?
If Interested, let me know.

I sent you a pm.
As far as just joining to trade phones, I am genuine. I read the forums regularly and finally joined. This forum helped me to unlock my T-Mobile galaxy s3. However, using the tmobile phone, I can't run the update, as the unlock does not hold after and my AT&T sim no longer works.
That's my reasoning for wanting to trade for an AT&T galaxy s3.

Just curious, what do you mean the unlock doesn't hold? Once unlocked it should remain so whether you flash a rom, firmware, mod, etc.

Well I had to flash back to stock rom to unlock the phone. I have avoided running the network update, guess was afraid that it wouldn't work. I really didn't want to have to flash it again and have to unlock it and be back where I started. So it should be fine to update, should cause no issues amd run fine with AT&T sim still?
Thats what you're saying right?
Thanks for info.
As I understand it, that is correct. Once its unlocked, you can Odin flash firmware, recovery flash roms, flash modems, etc.
If it helps, Ive never seen a single thread or question where someone was relocked.

Alright. I will go ahead and run the network update then. The notification doesn't go away. It is annoying!
Haha. I'll post back. I'd rather not have to trade if it works fine. Other than the annoying notification, the phone operates wonderfully.
If i flash the tmobile s3 rom on my att s3 will i get the 1700mhz band? I thought an att s3 on tmobile will only get 2g/edge service. Please let me know if someone knows.
Thanks A Lot,

Hello Everyone
I have a newb question so please dont judge
I have an unlocked and rooted T889V which i got from Wind Mobile. I have decided to gift it to my wife
as she is fed up with her little S3 mini and the crappy camera. She is currently with Rogers however she
does not have data or plan on using the internet. She will be sticking to Wifi as she either uses it home or at work.
Will this phone work with Rogers to make calls and send text messages or do i need to flash a different modem?
Thanks!
Yes, but the phone will need to be unlocked.
Sent from my SGH-T889 using xda app-developers app
Just unlock it. Insert Rogers SIM. Done.
No need to bother with enabling LTE since she won't be using data on it.
Although I am *very* curious to know if the (upcoming official) 4.3 update activates it since Vidéotron should be flipping the switch on their own LTE deploy soon-ish.
Sent from my SGH-T889V using xda app-developers app
Yup its already unlocked she just needs to buy a micro sim card cause hers is the regular big one. Thanks for the help guys.

Just a quick question. I am planning on traveling abroad next year and wanted to take my S3 and use another carriers sim. I am currently running TASK650 on it and the only info I have found pertains to stock ROM's and the network lock information that they contain. Is it safe to assume that I can use any other GSM carriers sim in my phone since I am running AOKP? Any help is appreciated.
If you're phone is unlocked you can use any SIM no matter what rom but you do unlock the phone either the 4.1.1 method or buying one

Perfect, thanks for the info. Looks like I'll have to downgrade and unlock.
I bought a note 4 on AT&T from eBay I was stupid and didn't read the advert properly my fault. Am wondering would I be able to flash my note 4 to UK unlocked rom at all? So basically it would work exactly the same as a note 4 bought hands free in uk. I have read there is difficulties in flashing international versions to work on AT&T due to network frequency but not much detail going the other way around
You can't flash anything on the AT&T version. It doesn't even have root at the moment and the bootloader is locked so you'll probably want to sell it.

If it's network unlocked it will work in the UK with your sim. Don't know if lte will work.
Yeah lte works and currently on ee phone works fine but just wondering if am able to flash it and install custom rom or original Samsung rom
I gurantee the AT&T Note 4 will NEVER see its bootloader unlocked. At this point in the game, it probably won't even see root.
I've read somewhere the android L will make it difficult for att to look bootloader and also android L will allow Uninstalling bloating software.

I read the opposite regarding the bootloader & rooting phones.
Title says it mostly. I'm switching my Verizon LG g3 over to AT&T by using their SIM and activating it. What I am wondering though is will I need to install an AT&T stock Rom or will my Verizon one work ?
So you are asking do you need to change your ROM to make Verizon SIM card working?

If there are some limitations that is not conencted with ROM and you cant do anything about that.
You are sure that your phone is unlocked to other carriers?
And sure that AT&T phones work with Verizon network?

I am sure that the Verizon LG g3 can accept an at&t SIM card and work on their gsm network. But I am not sure if I have to change the software (Rom) or the baseband (radio software) to at&t software
You cant flash the at&t baseband to the verizon model i dont think there are software limitations to changing network apart from verizon specific apps the only problem could be hardware but if you think it works on both networks i see no issue
