[Q] Cannot unlock My Nokia Lumia 920 AT&T
I really need your advice.
I bought a locked Lumia 920 AT&T. Yesterdar I received the unlock code from AT&T, BUT THE UNLOCK CODE DOESN'T WORK.
I inserted my Sim Card (Mobifone, Vietnam), and input 20 digits, it showed "Incorrect Pin", 9 attempts remaining
- I wrote the UNLOCK CODE (20 Digit) and shows a message: "SIM ERROR", "9 attempts remaining"
- I repeated it again, also got a message: "SIM ERROR", "9 attempts remaining"
- And so on....
How could it be, if the code is wrong, it should be "8 attemps remaining"..
What should I do now to unlock my phone?
Very appreciate for your help.
