PIN codes
The personal identification number (PIN) code and the universal
personal identification number (UPIN) code (four to eight digits) help to
protect your SIM card against unauthorized use. See “Security,” p. 68.
The PIN code is usually supplied with the SIM card. To set the phone to
request the PIN code, see “Security,” p. 68.
The PIN2 code (four to eight digits) 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. See “Security module,” p. 98. The module PIN is supplied with
the SIM card if the SIM card has a security module in it.
The signing PIN is required for the digital signature. See “Digital
signature,” p. 100. The signing PIN is supplied with the SIM card if the
SIM card has a security module in it.
