Enabling fixed dialing
Fixed dialing allows you to restrict your
outgoing calls and messages to selected
phone numbers, included in your fixed
dialing list. Once the service is activated,
you can call and send messages only to the
phone numbers from the list.
The list is protected by a PIN2. If you enter
an incorrect PIN2 more times than allowed
by your network operator, the SIM card
locks. Once the SIM card locks, you need
the PUK2 to unlock the SIM card. Contact
your network operator for more
information and the PUK2.
