T-Mobile S3 with AT&T Question - T-Mobile, Samsung Galaxy SIII

Hey guys,
So I just received my mom's T-Mobile S3 because she has moved on to the Note II. I have a plan AT&T, however, so I was wondering what problems I expect to receive because of this. I know that it is easy to unlock as I have done it for others before, but how are the phone bands going to be affected? Like will I be able to get AT&T 4G speeds? 3G? or just 2G?

You will get 4G speeds. Just no lte.

Oh ok. So I will be getting 4G HSPA+ or what? I thought AT&T was only 4G LTE?

I can verify this. Didn't even have to load an AT&T ROM.

You would think putting the word "question" in the title would be a good indicator that it should go in the "question" section.

Some people never grow or even do a Google search or basic reasoning skills to understand that threads can be reported to moderators without them having to read each one or that there really aren't that many new threads per day for forum.

Back to topic. AT&T's 4G is not as fast as T-Mobile just keep that in mind. While Tmobile's uses 42 download speed AT&T uses 21.
Mine d2tmo is unlocked and my friend have a d2att unlocked. We both trade sim cards to test our phones. Mine was getting 5-6mg download speed
and his was getting 10+.. You dont need a AT&T rom

At&t galaxy s3 to T-Mobile help

I got my unlocked s3 so I can use it on T-Mobile and hate edge so I was wondering if flashing the blaze modem would allow me to get 4g like the at&t galaxy note did.

Blaze is a .gs2, it would probably brick. I wouldn't risk it. If anything I'd try the t-mobile .gs3 radio.

I been thinking...instead of messing with all that and end up with a brick, why just not sell it on ebay and buy an actual Tmobile one or maybe trade with someone willing to. I would look at the selling price for an AT&T GS3 on ebay and how much would a Tmobile run and if it's not that much difference then pay the difference than end up with a possible brick. Plus I have read some forums where if you flash some things that are not meant for your phone you can even mess up the IME on your phone with no way to flash it back at the moment until someone comes up with a solution for it.
Not trying to be a jerk. Just a friendly reminder that this is not development related and needs to be in general or QA. I would repost there and report your thread to a moderator before the pitch forks come out.

When I put my friends note to t mobile it was the modem you had to flash , if your set on doing it , read a bunch on ways to do the note WITHOUT a custom Rom then find the same files you use in that ( the modem and if I remember right there was one other thing ) then go to the t mobile section in the sgs 3 thread and ask for help finding those files , but do a lot of reading first cause it would be a shame to brick your awesome phone

buy the t-mobile version. it doesn't work hardware not supported
im looking into this as well, i had the att note and flashed the tmobile modem worked like a charm so now im looking to do same with s3. if i find anything ill let you know
I don't thonk it will work at all. Att's S3 is LTE, correct. Tmobiles is not. Two different hw radios used.
If you do try it please post your results for others!

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.
Sent from my SGH-T999 using xda app-developers app
Have you guys tried the radios in the dev section by wildchld? I'm not sure it will work either but maybe worth a try. It has a script that backs up current radio and you can revert back. Atleast on T-Mobile s3 it does. Just need to reflash the restore zip to go back to previous radio. Again try at your own risk. There's a huge chance you can brick your device.

I don't think it matters if the Gs3 from T-Mobile doesn't have LTE, I used to have my Galaxy s2 skyrocket with LTE running on T-Mobile 3G/4G off a GS2 Hercules Modem.

Then by all means, give it a shot. I have no problem being proven wrong on stuff like this!
Just remember that was a different phone. And tmobiles radio Im pretty sure was confirmed to NOT support LTE. So they are different.
I'm definately looking forward to hearing someones results after trying! Just do some research on the two radios, and make sure the sw modem is on the same partition for each phone. (I think it will be. But if its not you could end up with serious problems)
Good luck to whomever tries it!
Sent from my SGH-T999 using xda app-developers app
Probably won't, the T-Mobile phone is pentaband so it will run 3/4G on AT&T, but their version isn't. Try it though.

[Guide] Sprint/Verizon Galaxy SIII Flash to Page Plus Cellular Tutorial [Video]

I No longer support this thread due to the lack of time I have lately. This video will show you how to get up and running on P+ with 1x data only.
This wil work for the Sprint, Verizon and US Cellular variant.
Yes I can get 3G but, the method is not allowed on this forum.
Please don't PM me asking how to get 3G as I will not reply.
Hit thanks if you watched this video please

Wow awesome Nevell. Thanks so much for this.
A few questions.
How different would it be to flash Straight Talk?
After flashing can I load ROMS like CyanogenMod and such without issue?
On the Sprint one yes but not on the VZW one. As far as flashing to ST you would need a donor phone. I won't go into details but that should be a start for you.
OP updated with new Verizon GS3 fully flashed with 3G youtube video demo.
I have been trying to flash verizon gs3 to sprint, and have talk and text but no data, I don't know what I am doing wrong. I have tried everything. Thanks for your videos and help is appreciated

Why not just trade your VZW GS3 for a Sprint GS3 on your local Craigslist?
I do have the sprint one, but I wanted the GSM capabilities of the Verizon one cause I travel over seas.

I can do 3G on the VZW 1 but I'm not going to discuss the method of doing it.
That's all I need to know if is doable and if it's stable steady 3G.

It works, just pop in the sim and power cycle. Theres a non verizon sim notification, but i'll figure out how to get rid of that soon enough. I would assume flashing a tmobile rom will do the trick

Never flash a ROM not meant for your device.
The Verizon phone looks for a cdma network that T-Mobile doesn't have, they use gsm. Two different technologies

You can flash roms from other provifders if the models are identical.
AT&T and T-Mobile roms can be flash back to back just make sure your modems are correct for your provider.
U CANT DO IT.
SELL UR GS3
AND FIND A TMO MODEL ON CRAIGSLIST!!!
I know it sucks, but thats just the way it.
Okay n00bs leave..
Seriously do some research before posting. My SPRINT HTC touch pro 2 works just fine on T-Mobile. So stop giving false info.
I found this. it may enable more than just roaming on GSM. I haven't read the entire thread or tried it myself well cause I has T-Mobile.
But it appears there may be some way to get it to work.
However from what I read.. seems you would be better off selling and buying T-Mobile (or possibly at&t if your area has T-Mobile 1900MHz) off Craigslist.

Sell it, buy a T-mobile GS3 is the BEST option and there's no denying that.

I had brand new windows phone from verizon before I moved to T-mobile and sadly i had let go my wphone, but I'm happy with my droid way way happy, sell it and you be fine just let it go.

You're assuming the only option is to change the phone's ESN, I didn't assume that, and was asking the OP how he went about getting the phone activated, nothing else.
Maybe the only option is an ESN swap, in which case I wouldn't be interested, but until the OP has told me otherwise, I'm curious.
