PUK Code: A Personal Unlocking Key code is used in GSM mobile phones, and some smartcards. Most mobile telephones offer the feature of personal identification number protection. After switching on the phone, the user is (optionally) requested for security reasons to 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 device or both become locked. A PUK code is then required to reset the phone, and can be obtained by contacting Smith Bellerby.
