    Default Phone now rooted how can I SIM unlock?

    Ok first I am a noob when it comes to this stuff so forgive me. Recently I was given an at&t S3 SGH-I747 for free. It has Jelly bean 4.3. I started off by trying to unlock the SIM so I could use my T-mobile card following several methods I found online...nothing worked. I then proceded to root the phone which of course Knox killed that effort...until yesterday. The phone updated SuperSu yesterday and allowed me to disable Knox so now its rooted. Now my question is there a way to unlock the SIM now that its rooted?

    I don't think you need root to unlock, though... Have you tried this? www.unlockphonenetwork.com
    I used that to unlock the very model you're trying to unlock. Sure, it's not free, but it's fast and hassle-free. Well worth the 10 bucks to save me the trouble. 30 minutes after the order was placed, they sent me the code and instructions, entered it, voil! Unlocked S3.

    I know the pay method, but I'm looking for the free method to do this

    Option 2 at your link would not be an option. Since he updated to.4.3 it would brick his phone to try to go back to 4.1. The only free option would be to contact AT&T and see if he qualifies for the Unlock code.

    Yeah... except AT&T's new unlock system is complete and utter nonsense, and more importantly it's not guaranteed that they'll send you the right code. I tried that route last December and eventually got a code that didn't work. I tried it again yesterday hoping the system had matured, but they sent the same code again.

    Which is why I'm looking for a free method like the op.

    I notices when i was going threw the build.prop on my lg optimus l70 ms323 that there Is a thing called keyguard.no_require_sim true. I dont know if that could be anything. And if you do try it not my fault if something bad happens.. only a lvl 10 paladin

    That doesn't have anything to do with the carrier lock. I'm almost certain all that does is allow your phone to be used if no SIM is inserted. I wouldn't mess around with the build.prop unless you know what you're changing and/or you have an up to date recovery image.

    I think you should call your carrier and find out they will do it the safe way.
