Hello, got locked out of the phone. While trying to switch network SIM cards message asking for PIN was read incorrectly and the wrong code has been put in causing to lock SIM network PIN and phone requesting network PUK. As thinking this issue could be solved with customer service we have already asked and received SIM network unlock PIN 8 digit code, but it is an invalid PIN as the phone has been locked. Trying to find who is able to provide this code as so far looking on google only solution comes to 3rd party company that sells certified SIM network unlock PIN and PUK codes.
So far message on the phone is ''SIM network PIN blocked. Enter SIM network PUK.''
Any suggestions would be very appreciated and maybe someone else also has done such a silly mistake.
Again much thanks for your time
If the phone is locked to O2 you will need an MCK to unlock it.
