PUC
PUC ist an abbreviation for the phrase personal unlocking code used
in GSM mobile phones. Most mobiles offer the feature of PIN protection. After swichting on the phone, the user is requested for security reasons to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong
code is typed in more than three times, either the SIM card, the mobile or both become permanently locked.
They can however be reverted to their original unlocked state through entering of a PUC. Mobile
users are therefore advised to keep their PUC written down in a safe place separate from the mobile.
Puc (Pontificia Universidade Catolica) is also the name of an important university in Brazil.
