A Personal Unlock Code (PUC), also known as a PIN Unlocked Key (PUK), is used in GSM mobile phones (phones with a SIM card). Most mobile phones offer personal identification number (PIN) protection. After switching on the phone, if the PIN security function is active, you can enter a 4-8 digit PIN enabling the phone’s non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the phone or both become locked. They can be unlocked by entering a PUC, provided by your service operator through verification.
