BYOP Unlocking used at&t phone with an unactivated new sim card?
I have received my unlocking code, I have a byop sim kit from a local store. Following directions directly I receive a different unstated message, unprovisioned sim instead of the expected type in unlock code. Does the sim card need to previously be active with a current number or provider? I have a tracphone sim kit brand new from a store. Where may I find the unlock code request area so I may input and unlock?
