No.
U have to at least unlock it.
Then go to specs of AT&T vs T-mobile frequencies. See what's supported. And then u'll see the light.
It will work as long as you first get it sim unlocked then flash the Tmobile Radio. Then you'll get Tmo's 4G.

I have both phones, an ATT SGS3 and the T-mobile Note 2. The SGS3 will work on TMO, but you get Edge data, not 4G. I don't know if you can actually unlock the TMO radio to get 4G. I don't that the phone actually has it and so far haven't found anyone that's done that.
Just wanted to let you guys know that LTE works beautifully on an unlocked ATT SIII.
so what if we flash an att rom that takes advantage of the lte radio in the phone (if we truly have one in the tmo version)
Now i am not sure on that. Maybe you should try
Gotta be worth a shot:thumbup:

The Tmobile S3 does NOT have an LTE radio...
not sure why you are suggesting to people to flash a ATT rom on the T-999...

identical hardware... it was just an idea. nobody can get the lte radio myth straight, so idk what to believe.
Maybe a dumb question but arent radios flashable? Beings as the hardware is the same coukdnt we flash an att radio and rom and use our phones like they were an unlocked att version

Yes it can be done but i have had bad experiences with radios causing serious OS issues. If someone had an S III to test with that would be great.
If you flash a att radio on a tmobile phone, You might be dealing with a serious brick.
I'm confused as to why this is up and getting attention lol? I might just be brain farting but, the person posts about his AT&T phone, with at&t bands (LTE) that they work on LTE??? I'm confused as to why this is news? Enlighten me maybe...

April Fools with a bricked S3! Don't know if I should laugh or cry...
Think the OP was just stating that his ATT S3 is working on TMO's LTE network...
The ATT has different hardware than the TMO S3...its not the radio software thats the issue...its the lack of a LTE antennae on the T-999
I believe the latest software update that tmo rolled out took out the LTE software that was in previous builds
While I don't thing we will get lte on our phones the thought of the hardware being different is hard to swallow. One of Samsung's deal with the s3 was hardware unity. With this they have one plant, one run to manufactur phones and when a carrier need a stock of phone all that was needed was software. This idea of a different model just for tmobile is hard for me to believe.
Once again I still don't see lte comung for us, so please don't assume I am giving any hope to get it
Sent from my SGH-T999 using xda premium
The Tmobile S3 has the exact same hardware as all the other US carriers including the antenna and modem, Tmobile just decided to use different lte bands. They will not enable the lte on the Tmobile S3.

If ATT S3 LTE can work on TMOB LTE network and T999 with same chip as ATT version.
sounds like TMOB trying to prevent S3 user to pull down they trial run LTE network.
and also prevent those people not in those trial site switch over other carrier.
I thought this was confirm a long time ago that the tmobile s3 doesnt support lte, As of an unlock att s3 to work on tmobile lte may be possible. if that the case It will be better off to sale or trade your tmobile s3 with an att version of it and you will have a s3 with lte
There will be a new s3 lte version of this phone at the end of this month...the current s3 is not the same as the att one so we will not have lte...

check this:
Double wrong. Verizon has a different RADIO frequency than AT&T and/or T-Mobile. It is impossible to update/change the radio for a sim on att/tmobile for it to work on Verizon phone. Like said before: Verizon is CDMA (code division network based) AT&T/T-MOBILE is GSM (global system network) now let me Synthesise, IMPOSSIBLE for the simcard to work in Verizon phone with out the appropriate radio for the network!

some of the verizon phones are "world phones" and have both gsm and cdma. all verizon lte phones have a sim card but only some have gsm. I don't know anything about the verizon s3 but you would be better off asking in the verizon s3 forums.
I know what world phones are. Was just stating to the other dude who thinks it completely impossible.

Not impossible. I get 3g on it and that's it. But when i change ROMs i have to redo the whole freaking APN settings again!!!

Yes you can, see this right now you can only get E speed on it. My S3 is actually flashed to Pageplus and I can use it with any GSM carrier here in the US, it's fairly easy to do but like I said you only get "Edge" speed for now. I've use Net10, Simplemobile and StraightTalk, any GSM will work you can also flash to other CDMA like Metro, Cricket or Pageplus.

See... This is what happens when a ignoramus tries to be smart .. You don't know what you're saying.. It is a proven fact that you can't put a GSM into a NON-gsm phone and expect it to work! (i tried it.. And it failed.. Invalid sim[in a unlocked vzw phone])
Now, this is posted in the wrong thread.

yes but havent tried
there are several places saying it is totally possible and ive called verizon trying to see what they would say and the answer i got, at least for out of the country GSM, is that the S3 comes "unlocked already" and you just put in the sim card from whatever out of country carrier you want. apparently that came with the 4.1.2 update to the phone. Now putting with a us carrier might be different but i cant try it because i have my phone flashed to metropcs and i cant just put a metro sim card in it. here a few places i found just by looking on google

U actually can use the Verizon variant s3 on tmobiles network as the s3 is a world phone, now here's where and why most ppl don't, Verizon's network is CDMA as we all know and T-Mobile is a gsm network, so with the s3 being a world phone it can be used on a gsm network but u will never see 4g or even real 3g speeds, Verizon's s3 doesn't have the ability to pick up anything but "E", edge speeds on T-Mobile so is it really worth it? Not in my opinion, if I'm going to blget an s3 I want the full functionality of the devices capabilities, just saying though lol

I can say with some certainty that u will not see 4g using a Verizon variant s3 on T-Mobile network, yes its a world phone and yes u can get it to "work" on T-Mobile but it doesn't have the right kind of internal for gsm 4g network speeds, the most u will see out of it is E or edge, 2g speeds, at least until the towers get updated

I can't say for certainty but as of right now any unlocked world phone from a CDMA based network will only pick up 2g or edge network speeds, it may say 3g or even 4g but believe me unless ur in an area where towers have been remapped u will not see anything above 2g ,maybe base 3g ,only because the radio isn't designed to pick up the gsm frequency, now in the near future cdma will be phased out so u may be able to get 4g in the future but not as of now

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.

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.?

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!

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.

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.

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.

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?
Maybe you should try posting in the ATT S3 forums? I'm pretty sure that most people here have the TMO variant, while you are looking for tweaking of the ATT variant.

Don't flash a T-Mobile modem, it will brick. T-Mobile and AT&T use different frequencies for hspa+ in most places, and the AT&T version doesn't have the hardware to pick up the most used T-Mobile frequency I believe. So you're probably stuck with edge

So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?

You ARE stuck on edge.... I know it sucks. unless you are in a refarming area http://www.airportal.de/ , (major cities) your AT&T S3 1900/2100Mhz high speed data (4G) band will not work on T-Mobile's 1700/2100Mhz networks. I would sell it on e-bay or craigslist and got your T-mobile S3 again. or get the T-Mobile S4 after you sell your att S3 :cyclops:
