Hello,
So I used the instructions from this thread to unlock an ATT S3 for international use. I don't have the international SIM yet and currently have Sprint so I don't have a SIM card. I used my old T-Mobile sim and get the "SIM not provisioned MM #2" message. Would this mean that it is unlocked?
Hello, the question is can I use my rogers S3 ( locked to rogers ) with att (prepaid sim card)?
From the pictures you can see sales code shows ATT and device type is d2att. Does that mean can I use att sim card on my S3?
My thinking is to change the APN since my phone is already d2att.
The phone should work after you have it unlocked.
Are there by chance any roms that would allow for a psuedo sim unlock for gsm sim cards on the Sprint variant of the M8? I have FusionRom V6 for the LS990 Sprint variant and there is absolutely no work involved in popping an ATT/Tmobile/international sim and getting it to get HSPA+/LTE.
Changing roms will not sim unlock a phone unfortunately
Is the Sprint variant factory sim unlocked? Can I put AT&T sim and it would work?
I successfully went to 2ARF4 on this and it's now a G960U1 but I'd like the AT&T wifi calling, is it possible to flash the AT&T software to gain that or does it have to be a AT&T branded device for their system to register it? If it's possible which OS version should I get, I don't see a ATT version of the one that's on here or anything that would be the alternative.
You can get Sprint S9 or S9+ variant unlocked through Ebay:

Also can do Bad IMEI devices also.
After you're unlocked should convert to ATT software when you insert sim.

It hasn't converted to AT&T software on the U1 firmware I flashed. That's why I started the thread to see if anyone else has been able to

First SIM unlock the phone...
Then, Use an unlocked and generic firmware like g960usqs3brj6 and flash with newest Odin.... Use csc NOT home csc and do NOT insert a SIM....
Factory reset, boot phone and setup to home screen... Then just pop in an AT&T sim and click restart device. It should install everything you need for att. I am running att video calling and all other features on my g960u with the above firmware and have no problems... Lists ATT/ATT/SPR under service provider now... Good Luck!
