I get the message “Unsuccessful Unlock”
First check the IMEI you provide by type *#06# on the phone. If you provide the correct IMEI, then continue.
If you get "Network Unlock Unsuccessful" message, don’t worry. This is a very common problem and there are different ways to solve it. Just make sure your phone is asking for the unlock code.
