Personal Unblocking Keys (PUKs) for your mobile phone.
Three PUK Codes
Three Personal Unblocking Key
Three PUKs, or personal unblocking keys, can be obtained by phoning Three on 08707 330 333 (or 333 from your 3 phone) or by visiting the Three website.
The PUK can be used to unblock a mobile phone which has become 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.
Mobile phones are also blocked when they are reported stolen and if there is an outstanding payment on the account.
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. IF you are looking to change your mobile phone network provider and want to keep the same telephone number, then you need a PAC code - see www.paccodes.co.uk for more information and to get you PAC code.
