Ok guys heres the deal. Am currently on tmobile contract plan, planning on canceling it soon. Want to go with at&t prepaid data plan. What do i need and what do i need to do to make my tmo gs3 to work with att 3g/4g network? Data and mms along with txt and all. Im pretty sure its more than just cut the sim and slip it in. Or is it? Im a complete noob so be gentle lol. Thanks in advance.

It actually is pretty simple, but you have to have TMobile give you the unlock codes to your phone. Basically once you have the ATT Sim, insert it and your phone should prompt you to enter a carrier unlock code. This is where you enter said code once obtained from TMobile.

You may need to set your APNs if you make the switch and lose data/signal. Just Google ATT APN settings and it will explain what you need to set. (Prepaid plans might have different APNs so make sure you find the right one for your plan)
As far as obtaining the unlock codes from TMobile, you could try saying your leaving the country on extended vacation, that may help, but if your still in contract and they refuse you there's nothing you can do.. other than call back and get a different rep.

Thanks man^^
I spoke with a tmobile rep and they are going to email me the unlock codes within "72hrs" ill be waiting. So after that is done i will proceed with the rest of the process with an att sim.
Yes i will Google the apns once i get the rest sorted out. Looks like its not that hard after all. The most hassle is going to be getting a sim activated since theres no store near me gonna have to order one online

You can always go with StraightTalk. Their plans are cheaper than att prepay and have semi unlimited data.(something att prepay doesnt). And they have tmobile compatible SIM cards. Which doesn't required unlocking. If you receive better service from att then get the att compatible SIM. Will require unlocking for that though

I do not own a TMobile device, this is just from research I've done. I don't know if there is a work around.

I'd go with Straight Talk also. I just switched my girlfriend over to it because she was paying over $100 per month for a decent service. She doesn't get LTE (but her phone doesnt support it anyway) but for $45 unlimited data, text, calls, its worth it. And it's on the AT&T network.
Well i already had ordered the prepaid micro sim card for at&t. That's what im waiting on right now, after that i will go to the next step.

Ok SO I could not find a proper thread for this since there are SO many threads. The issue I'm having is I got a Samsung galaxy S III that was unlocked, and after I put my ATT sim into it I could recieve texts and calls but I could not recieve data. So I rooted it and applied clockwork with all my mods and figured I could find some setting that would fix it... well I was wrong. I tried global, GSM and LTE settings none of which would give me data. If there is anything anyone can do to help I would be more than appreciative.

You do realize you're trying to use a cdma phone (verizon) on a gsm network (at&t), right? Different radios. Different technology. Won't work
Well it was unlocked at the phone has a gsm option so if it wasn't compatable I don't see why they would have the option there to actually use a gsm network.

You need to read more.
this phone only supports GSM with EDGE data.* This essentially means that you'll get 2G data speeds (unless you have a WiFi connection) because it doesn't support UMTS/HSPA+ which is required for international and U.S. 3G data. the 4G LTE frequency supported by this phone is only used in the U.S.* For those who don't know UMTS/HSPA+ is the 3G technology used by GSM carriers internationally (and used by AT&T and T-Mobile in the U.S.) which is different from the CDMA/EV-DO 3G technology used by Verizon and Sprint.*
This phone IS unlocked, that part is correct. But only for gsm carriers
So its preventing me from recieving ANY form of data possible?? It is a Verizon phone and I have ATT so you mean it doesn't support GSM then right?

If I'm not mistaken, some Verizon devices will not work on US gsm networks even if unlocked, only foreign gsm networks.

If you are going to stick with AT&T, that is the way to go if you want to have data. No worries. Stupidity is only if you didn't learn anything. You had ignorance of the situation and now your don't. Do some research on any phone before you buy next time (especially if branded from another carrier). This can save you a lot of headaches as you have just learned. Just remember some basics from this forum. Good luck.
Have an AT&T i317 unlocked with a T-mobile data sim.
I've done the tweak to enable the 3G/4G bands, a la http://forum.xda-developers.com/showthread.php?t=2068041
But now T-mobile added LTE in a few markets. I drove through one and suddenly got no data access. This is with "preferred network mode" set to LTE/WCDMA. If I switch to GSM/WCDMA, all is well (it sticks to the HSUPA and H+). So clearly it thinks it's on LTE but the phone can't access the T-mobile LTE.
I'm using Cyanogenmod 10.1, android 4.2.2, which also makes the model number show GT-N7105 instead of i317.
any tweaks to add the LTE? do i need to dump CM and use a diff ROM? do i need to go back to stock first to do any of this? (Right now, I can no longer dial *#7284#)
Thanks!
I am having a similar issue, I have a sgh-i317 with aws mod and the phone is not picking up t mobile lte even when placed next to a sgh-t889 that is getting it. Lte works with att sim but not working with tmobile sim. Any help would be great. I have tried many roms and modems and reflashing aws mod. Roms inculde jedimaster13/14 jedi x13/14 both att and tmobile versions and clean rom and stock 411 and stock 412
I figured it out see

Does the AT&T version have LTE? If it doesn't have the capability, but he modem is telling it to access it when it sees it, that might be why it dropped out completely. I'm mostly curious to see if AT&T LTE devices can use t-mobile's LTE network because I want to get an s4 active and I don't want to lose LTE by making that switch.
Try this for me, instead of that model number you have. Change it to the T-Mobile model#. Which is going to have to b done thru the build prop. Then reboot. Then go try and c if you pick up lte.
Because I just flashed a AT&T Rom on a T-Mobile GN2. And I pick up lte just fine with my AT&T SIM in there! And no AWS MOD what so ever. But the MODEM is still TMO, it'll always b TMO. Flash a att modem on a TMO GN2. Brick city.
Let me know what happens just curious!!
Edit: the Rom I flashed was SKY NOTE 9. No modem included!!!

WELL, here's your answer.
Maybe they getting the device at a cheaper price. Which would make someone but it. Instead of spending a lot more to have have the carrier brand you need. FYI
Both the phones are exactly the same. Besides the model# and done bloat. Like I said above, if it's unlocked it'll work, with both carrier's. So why not have that option to switch... and one more thing being able to take the phone internationally, and pop a SIM inside and ya have service. No roaming !!!
Just my 2¢® 2 you're question...

When a t-mobile version is available, I do buy it, but with ATT exclusives, that's not an option. For instance, I want the s4 active for its water resistance. T-mobile will soon offer the xperia Z, but when you compare the features and perormance, the s4 active is better, so for the money i'm willing to spend on a smartphone, i'd rather have the s4 active.. the hardware is capable of t-mobile LTE, but it still has to be configured properly with firmware and software to use the radios correctly. Since radios are some of the hardest pieces of firmware to alter, it's worth doing this investigation / collaborating to find work-arounds.
I didn't get tmobile lte on my at&t note 2 until I flashed the new at&t radio. That's all that had to be done. I'm using Skynote9 too. I did the aws mod again so I could get h+ 4g speed enabled and now is a flawless tmobile phone. Let me know if it works for you.

I have a Galaxy S III from AT&T. I got it unlocked and activated on T-Mobile last month.
Now, I went a month on AT&T roms, but recently I flashed SlimBean, which is dual carrier. My phone immediately connected to LTE! Never had I seen LTE on TM's network on this phone before, so I take that to mean I need to run T-Mobile ROMs to get LTE service.
So just now I tried to flash BeanStalk for d2tmo, but it won't let me install it because, of course, it's not made for this phone. From what I have read, though, it should work fine on my phone. How do I override this failsafe so I can run T-Mobile roms on my AT&T gs3?
"You do this with 7-Zip/WinRAR
Note: DO NOT EXTRACT ROM!
Open the zip file, do not extract, go to:
/META-INF/com/google/android/updater-script
1)Open updater-script with a script editor such as notepad/notepad++ (makes things 10x easier), or gedit if you use linux
2)Delete the first line of code (all the way up to the first semicolon you see) and delete the first semi-colon as well
Do not go past the first semiclon when deleteing and DO NOT forget to delete the first semicolon."

Well I had LTE / GSM / WCDMA selected in the settings on CyanogenMod for the I747 and it wasn't connecting to LTE. Only HSPA+. So either it's the ROM, or T-Mobile launched their LTE network here at the same time I flashed SlimBean.
I'm running stock i747 and I get Lte all over Chicagoland. I'm rooted now, but I got it before I rooted too. I'm using the stock 4.1.1 that came with the phone, picked it up for $180 a few days ago...Wow this thing is awesome.
Thinking about going with Dandroid tomorrow...still deciding att or T-Mobile version.

Please do let me know! When I was running the AT&T roms, I had "Simple Mobile", "StraightTalk", and "T-Mobile". I tested and all of them worked, but just connected to HSPA+.
Now that I've installed a T-Mobile rom I am also getting "Solavei" and "T-Mobile LTE." When I select T-Mobile LTE, my phone connects to the LTE network. When I have the regular T-Mobile option selected it doesn't connect to data at all.
EDIT: I am testing again, and I actually can connect to HSPA+ on the regular T-Mobile APN. Let me walk around and see if I can make it connect to LTE. Then I'm going to flash an AT&T rom and try to get it to connect to the LTE network by manually adding the APN. I'll let you know how it goes.
Can the APNs determine what type of network you connect to?
I'm just curious what APN settings you're using to connect to LTE on the AT&T rom.
Okay, here's another update as the result of some testing with my T-Mobile rom:
When I switch to the "T-Mobile US" (no LTE) APN, I noticed that my data cut in and out sort of randomly. I speculate that the reason for this is because it was trying to connect to the LTE network but couldn't get data on it because my APN was set incorrectly. This is what confused be before. I switched the data mode to GSM / WCDMA preferred and it immediately connected to data, and was consistent.
So I think if I just add the T-Mobile US LTE APN to an AT&T rom, it should connect to LTE properly?
A long time ago when I was just on the T-Mobile US APN on an AT&T rom, it was doing the same thing with being inconsistent with the data connection until I disabled LTE so it stopped trying to connect. I'll take the fact that it tried to connect but couldn't as enough evidence that it knows how, it just needs the APN.
Yay figuring things out! Sorry if my words are confusing or I maybe I should have made a new thread for this. I'm new here, and I'm not sure how this kind of things work.
Thanks for the help in figuring that out!
Sorry about the sidetrack, I'll work on getting 4.3 next, and let you know how that goes.
Here's what I've got

Ok so I have just received my unlock code from Tmobile for my Samsung S3.
I have just ordered a micro sim from AioWireless since I have decided to give them a whirl and see if I would get better signal in my area (my signal has been blah for the last year).
So with that in mind, Do I still install roms from the this forum(s) and just change APNs or do I have to start using roms from the At&t S3 forum?
Just trying to figure out the best way to go, and most importantly the correct way.
Thanks in advance.
You can still flash ROMs meant for the t999 and change the APNs...you should also be able to flash AT&T Roms without an issue, just make sure the APNs are correct.
