■ Access codes
You can use the access codes described in this section to avoid unauthorised use of your phone and
SIM card.
The access codes (except PUK, PUK2 and keylock codes) can be changed by using Menu 4-5-6. See the
following section.
Security code (5 digits)
The security code can be used to avoid unauthorised use of your phone. The factory setting for the
security code is 12345. To avoid unauthorised use of your phone, change the code in the Settings
menu, see ’Security level (Menu 4-5-5) on page 86 and ’Change of access codes (Menu 4-5-6)’ on page
87. Keep the new code secret and in a safe place separate from your phone.
PIN code (4 to 8 digits)
The PIN (Personal Identification Number) code protects your SIM card against unauthorised use. The
PIN code is usually supplied with the SIM card. When the PIN code request is enabled (Menu 4-5-1),
the code is requested each time the phone is switched on.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required to access some functions, such as charging
unit counters. These functions are only available if supported by your SIM card.
