I'm not sure, but maybe you can ask the AT&T customer care to give you the unlock code as well as the method to do it.

That's what I tried for my S2 and S3. I had them under contract. And if you buy it without contract, shouldn't it be unlocked already? Just curious!

I'll ask about the unlock process to AT&T tomorrow and let you know if the same trick works or not

Unless I'm not mistaken, you are not talking about rooting the device already, are you!

If you ever want to modify your phone, I recommend returning during your 14 day trial period. Otherwise, you will be stuck with a worthless piece of junk. Although nobody has verified this yet, the SM-G900T (tmobile) appears to support the same bands but I need someone to test with a ATT SIM

The T-Mobile version (SM-G900T) supports all of the frequencies of AT&T, plus WCDMA 1700 MHz. Additionally, it's the only variant with an unlocked bootloader. I know people using it on AT&T.

That question makes no sense. By "bootloader unlocked", I mean that the T-Mobile version is the only variant that lets you flash anything without stopping you (e.g. custom ROM, custom recovery, custom kernel). Depending on what you flash, you will trip Knox though.

I'm not getting answer of main question, can I flash custom rom or root Samsung SM-G900A and use it with any sim card even if it is blacklisted by AT&T
