General information

■ Access codes

Security code
The security code (5 to 10 digits) helps to protect your phone against
unauthorized use. The preset code is 12345. To change the code, and to
set the phone to request the code, see "Security," p. 59.
If you enter an incorrect security code five times in succession, the
phone ignores further entries of the code. Wait for 5 minutes, and enter
the code again.
PIN codes
The personal identification number (PIN) code and the universal
personal identification number (UPIN) code (4 to 8 digits) help to
protect your SIM card against unauthorized use. See "Security," p. 59.
The PIN code is usually supplied with the SIM card. Set the phone to
request the PIN code each time the phone is switched on.
The PIN2 code (4 to 8 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. 92. 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. 93. The signing PIN is supplied with the SIM card if the
SIM card has a security module in it.
PUK codes
The personal unblocking key (PUK) code and the universal personal
unblocking key (UPUK) code (8 digits) are required to change a blocked
PIN code and UPIN code, respectively. If the codes are not supplied with
the SIM card, contact your service provider for the codes.
