Access codes
The PIN code supplied with the SIM card protects the card against unauthorized use.
The PIN2 code supplied with some SIM cards is required to access certain services. If you
enter the PIN or PIN2 code incorrectly three times in succession, you are asked for the
PUK or PUK2 code. If you do not have them, contact your service provider.
The module PIN is required to access the information in the security module of your SIM
card. The signing PIN may be required for the digital signature. The barring password
is required when using the call barring service.
To set how your phone uses the access codes and security settings, select Menu >
Settings > Security.
