Notes about fixed dialing
• If a SIM card with fixed dialing that is activated is inserted into a
phone that does not support fixed dialing, the SIM card is rejected.
• If you try to add a name without a number to the fixed dialing list,
you will receive an error message.
• If you try to browse the fixed dialing list but have not stored any
numbers, Fixed dialing list empty appears in the display.
• You cannot access SIM memory manually (view or copy numbers on
the SIM card) while fixed dialing is active.
• CLOSED USER GROUPS
This network service specifies the group of people whom you can call and
who can call you. Default resets the phone to use a user group that the
SIM card owner has agreed upon with the service provider.
Note: When calls are limited to closed user groups, calls may be
possible to emergency numbers programmed into your phone (for
example, 911). Enter the emergency number and press the Talk key.
The number appears in the display after you have keyed in the
last digit.
