Network services
Caller ID
You can prevent your phone number from being
displayed on the phone of the person being called.
Note: Some networks do not allow the user to change
this setting.
The following options are available:
Default: the default setting provided by the
network is used.
Hide number: your number does not display on
the other person's phone.
Send number: your number is sent each time you
make a call.
Closed user group (CUG)
This network service allows incoming and outgoing
calls to be restricted to a selected user group. You
may be a member of up to ten user groups.
For details on how to create, activate, and use a
closed user group, contact your service provider.
Example: A company lends SIM cards to its
employees and wants to restrict outgoing
calls to members of the same team.
