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. 73.
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. 73. 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. 107. 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. 108. 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) is
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.
