Fixed dialing

Select Menu Contacts

Fixed dial contacts.
With the fixed dialing service, you can restrict calls from
your device to certain phone numbers. Not all SIM cards
support the fixed dialing service. For more information,
contact your service provider.
When security features that restrict calls are in use (such
as call barring, closed user group, and fixed dialing), calls
may be possible to the official emergency number
programmed into your device. Call restrictions and call
forwarding cannot be active at the same time.
You need your PIN2 code to activate and deactivate fixed
dialing or edit your fixed dialing contacts. Contact your
service provider for your PIN2 code.
