PIN codes
The personal identification number (PIN) code or the universal personal
identification number (UPIN) code help to protect your SIM card. The UPIN code is
usually supplied with the SIM card. Set the device to request the code each time
the device is switched on.
The PIN2 code may be supplied with the SIM card and is required for some
functions.
The module PIN is required to access the information in the security module. The
signing PIN is required for the digital signature. The module PIN and the signing
PIN are supplied with the SIM card if the SIM card has a security module in it.
