Security

When security features that restrict calls are in use (such as call restriction, closed user group,
and fixed dialing), calls 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.
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 restrictions — to restrict incoming calls to and outgoing calls from your phone (network
service). 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. When the fixed dialing is on, GPRS connections are not possible
except while sending text messages over a GPRS connection. In this case, the recipient's
phone number and the message center number must be included in the fixed dialing list.
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 whenever a new SIM
card is inserted into the phone. If you select Memory, the phone asks for the security code
when the 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, or
restriction password
Code in use — to select whether the PIN code or UPIN code should be active
Authority certificates or User certificates — to view the list of the authority or user certificates
downloaded into your phone. See "Certificates," p. 53.
Security module sett. — to view Secur. module details, activate Module PIN request, or change
the module PIN and signing PIN. See also "Access codes," p. 7.
