I have personally done this on a S3 LTE and it worked but you do this at your own risk

Menu not exist
Press back key

It seems to be only available on certain firmwares. I have checked about 10 S3's and the option is not there. Its a pity because there is no other way to permantly unlock the s3 ATM.

Thanks for the Post.
Your method worked well in my sister's Galaxy S3 LTE .But when I tried it in my Galaxy S3 mini it didn't work(I guess I am not that lucky). So,I contacted my service provider to get the unlock code but they said I have wait until my Contract is over which is two years.So,I searched many site and found Unlock code for cheap price in

Onlinegsmunlock.com

and unlocked my phone.
