This article describes PUK codes. If you are looking for a PAC code visit www.paccodes.co.uk, and if you are looking for a network unlocking code (NUC code) visit www.nuccodes.co.uk...
PUKs, or personal unblocking keys, are used to unblock a mobile phone which becomes blocked. Mobile phones may become blocked when a PIN (personal identification number) is entered incorrectly on three consecutive occasions. In some instances, the phone may become blocked, which requires a PUK to unblock it, and in other instances, the SIM (Subscriber Identity Module) card itself becomes blocked and again will require a PUK to unblock it...
It is important to differentiate between unblocking phones (using a PUK) and unlocking mobile phones (using another type of code). More information on unlocking phones will be available here in the very near future.
