■ Security
When security features that restrict calls are in use (such as call barring, 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 code every time
the phone is switched on. Some SIM cards do not allow the code request
to be turned off.
PIN2 code request — to select whether the PIN2 code is required when
using a specific phone feature which is protected by the PIN2 code.
Some SIM cards do not allow the code request to be turned off.
Call barring service — to restrict incoming calls to and outgoing calls
from your phone (network service). A barring password is required.

Fixed dialling — to restrict your outgoing calls to selected phone
numbers if this function is supported by your SIM card
Closed user group — to specify a group of people whom you can call and
who can call you (network service)
Security level > Phone — to set the phone to ask for the security code
