Settings
Lock if SIM changed - Select Yes if you want the phone to ask for the lock
code when an unknown, new SIM card is inserted into your phone. The
phone maintains a list of SIM cards that are recognized as the owner’s
cards.
Fixed dialing - You can restrict your outgoing calls to selected phone
numbers, if supported by your SIM card. You need the PIN2 code for this
function. When this function is active, you can only call those phone
numbers that are included in the fixed dialing list or which begin with the
same digit(s) as a phone number on the list.
To view the list of Fixed dialing numbers, go to
Menu→ SIM→ Fixed dialing.
Options in the Fixed dialing view are:
Open, Call, New contact, Edit, Delete, Add to Contacts, Add from Contacts, Help
and Exit.
Note: When Fixed Dialing is set on, calls may be possible to certain
emergency numbers in some systems (911 or other official
emergency numbers).
To add new numbers to the Fixed dialing list, select Options→ New
contact or Add from Contacts.
Closed user group (system service) - You can specify a group of people to
whom you can call and who can call you. For more information, contact
your service provider. Select: Default to activate the default group agreed
on with the service provider, On if you want to use another group (you
need to know the group index number), or Off.
Note: When calls are limited to Closed User Groups, calls may be possible
to certain emergency numbers in some systems (911 or other
official emergency numbers).

when you are using a SIM card service.
