When the keypad is locked, calls may be possible to the official emergency

You can set your phone to lock the keys automatically after a time you specify. 
See “Phone settings” on page 36 to activate this feature.
 • Access codes
The following access codes allow you to secure your phone from unauthorized 
use. To change access codes, see “Security settings” on page 39. Keep the new 
codes secret and in a safe place, separate from your phone.
Security code—This code, supplied with the phone, protects your phone against 
unauthorized use. The preset code is 12345.
PIN code—This code, supplied with the SIM card, protects the card against 
unauthorized use. Turn the PIN code request on so that the code is requested each 
time the phone is switched on. If you enter an incorrect PIN code three times 
in succession, the SIM card is blocked. You must enter the PUK code to unblock 
the SIM card and set a new PIN code.
PIN2 code—This code is supplied with some SIM cards and is required to access 
certain services, such as charging unit counters. If you enter an incorrect PIN2 
code three times in succession, PIN2 code blocked appears in the display and 
you will be asked for the PUK2 code.
PUK and PUK2 codes—These unblocking codes may be supplied with the SIM 
card. For more information, contact your service provider.
Call restriction password (4 digits)—This password is needed when using Call 
restrictions. You can obtain the password from your service provider.
