■ Security
When security features that restrict calls are in use (such as call restriction,
closed user group, and fixed dialing) calls still may be possible to the official
emergency number programmed into your device.
Select Menu > Settings > Security and from the following options:
PIN code request — to set the phone to ask for your PIN or UPIN code every time the
phone is switched on. Some SIM cards do not allow the code request to be turned off.
Call restrictions (network service) — to restrict incoming calls to and outgoing
calls from your phone. A restriction password is required.
Fixed dialing — to restrict your outgoing calls to selected phone numbers if this
function is supported by your SIM card
Closed user group (network service) — to specify a group of people whom you can
call and who can call you
Security level > Phone — the phone asks for the security code whenever a new
SIM card is inserted into the phone. Select Memory and the phone asks for the
security code when SIM card memory is selected and you want to change the
memory in use.
Access codes — to set the PIN code or UPIN code in use or to change the security
code, PIN code, UPIN code, PIN2 code, and restriction password
Code in use — to select whether the PIN code or UPIN code should be active
Pin2 code request — to select whether the PIN2 code is required when using a
specific phone feature which is protected by the PIN2 code
