Unlock my phone
I bought in full an AT&T phone and I used to have an AT&T number. In myAT&T account, I had the number and the phone. Now, my AT&T number is gone and I no longer have it. I still have the phone and when I try to unlock it using AT&T unlock tool, I get asked for the passcode and the phone number. I enter my old AT&T number and the passcode that I had but I fail to unlock it. I tried unlocking using the IMEI number, but also I can't because I get the reason that the phone is currently active on someone else's account! But it's my phone and I bought it in full, and I can't find it listed in myAT&T account in order to continue the unlocking process!. Any help is really appreciated.
