• SET UP A CLOSED USER GROUP
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 certain emergency numbers in some networks (such as
911 or other official emergency number).
