■ 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 or UPIN code
every time the phone is switched on. Some SIM cards do not allow the
code request to be turned off.
Call barring service (network service) — to restrict incoming calls to and
outgoing calls from your phone. 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 (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 change the security code, PIN code, UPIN code, PIN2
code, and barring password
Code in use — to select whether the PIN code or UPIN code is active
Pin2 code request — to select whether the PIN2 code is required when
using a phone feature that is covered by the PIN2 code
