Hello there, this is my issue. I am in the process of moving from the U.S. to Africa, and one of item to process during this transaction period was to cancell my account with ATT and unlock my phone so I can use it with another local provider. In the process of unlocking it I entered the code more than 5 times which prompted the phone to be locked. Message on the screen says 'MCK - Network Unlock - Code Blocked'
I have spoken with Att and they say they cannot unlock the phone, and it can only be used by someone with ATT provider. Can someone help me with the issue?
