Hi all,
Been modding my s3 on t mobile for a while. Moved to washington, and t mobile has no service in about 10 miles of where I am. Att has full 4g here, so I unlocked it and got the sim for their go phone plan. Had to put in the proper apn, but have data working fine now. Unfortunately, some t mobile processes keep telling me that my sim is "invalid". It's annoying. Can I flash a custom att rom, and if so, can I use the modem flash as well, or do I need to avoid flashing the att modems?
I'm running the d2tmo frosty jellybean V11.6 currently.
Thanks

I'm thinking seriously of getting this phone on the Virgin Mobile network. I've already located a root, recovery and kernel that is listed as working on the Virgin Mobile version. I'm just wondering if there are any compatible roms that will work. I'm pretty sure most of the sprint roms will flash and boot, but I'm worried losing data and mms.

All Sprint and Boost roms will also work with vm. You just have to change the mmsc url so that you can send mms. I also have a deodexed/debloated VM stock jellybean Rom that works well too. Good luck, and enjoy!

Before you jump on purchasing the GS2, the GS3 is now being released this month on Virgin Mobile. Just google "Virgin Mobile GS3" if you wanna look into it some more.
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."

You'll want to delete the highlighted text in the updater-script, then save it. You shouldn't run into anymore problems or errors when flashing the ROM.

And the Rom won't give you LTE. Most T999 roms will show 4g, but look in settings for your true connection. You probably had it all along.

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.

What are your APN settings?

Never changed any settings, except picking T-Mobile when it first booted with the T-Mobile SIM....I'll have to take a look at them later.

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.

always flash for your device, not your carrier. just a good simple way to look at it i think

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.

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.

Hi all,
Just had a quick question, as I am thinking about swapping carriers from AT&T (horrible customer service and technical support). I currently have the AT&T i747, but I am thinking about switching from AT&T to T-Mobile as they are now providing Unlimited Everything for $70 per month. My question is, if I unlock my i747 for T-Mobile, which section in XDA would I go for custom ROMS, Kernels, tools and utilities and such? Would I stay here since the hardware is AT&T or would I need to migrate to the T-Mobile forums? Thanks in advance for your assistance.
In order to enable high speed data on you i747, you'll need to enable AWS frequencies on your s3 and unlock it. You could continue to use d2att ROMs if the model # on your phone does not get changed by using the T-Mobile mod.
You can use either sections, but you need to stick with i747 modems and firmwares.. And if you want to take advantage of T-Mobile's WiFi calling then you need a T-Mobile ROM.. You may or may not have to do the AWS mod. if you live in a refarmed T-Mobile area, then you'll get 4g and 4g lte fine, if not, then you may only get lte with edge being a fall back if you don't do the mod.. I used an i747 with T-Mobile and luckily my area is refarmed so I had 4g and 4g lte with no mods needed

OK, so I switched to T-Mobile today and my Mobile data and WiFi are picking up only one bar. Do I need to flash or change a modem setting or something?

The modem should not affect the wi-fi performance but it will affect data performance.

Alot of people overlook the fact that T-Mobile uses which frequencies? Ones that are higher 1700+ mhz and someone like at&t uses 850+ the lower frequencies travel farther and penetrate walls and buildings. In my area if you get T-Mobile it os because you dont want to talk on the phone ever again...
Good luck
