Security Codes on Mobile Phone

The lock code is a number that prevents unauthorized persons from using your phone. The security code prevents the unauthorized use of certain features or the accidental alteration of essential programs used by your phone. These control codes are for your protection. At the factory your phone was assigned a default lock code (1234) and security code (12345). For security reasons, it is imperative that you change the codes. For complete instructions on changing your codes, please refer to your user guide. If you have forgotten your phone’s lock and security codes or cannot access certain features, please contact your dealer or the nearest Authorized Service Center to reset the codes. Source: Nokia
