your SIM card is disabled and your phone displays the message 
SIM Blocked

code, which you can obtain from your service provider. After 
entering the PUK code, you will be prompted to create a new 
SIM card PIN code.
Caution: If the unblocking attempt is tried unsuccessfully 10 
times, the SIM card is permanently disabled and your phone 
displays the message
