CLOSED USER GROUP (Menu 5 7)
This network service allows the restriction of outgoing calls to
and incoming calls from a selected group of people, called
the user group.
This function comes in handy, for instance, when a company
lends a SIM card to its employee and wants to restrict the
outgoing calls to members of a working team.
Note; When calls are limited to Closed User Groups, calls
may be possible to certain emergency numbers in some net-
works (e.g. 112 or other official emergency number).
You may be a member of up to 10 user groups.
For details on creating a user group and activating this
service, contact your network operator.
Press Menu 5 7 to enter this function.
Press or to reach one of the following options:
None
Calls can be made and received in the normal way. You
can use this option only if you are entitled to do so. For
details, contact your network operator.
