Menu functions
Network Selection
This network service allows you to manually select the
network to be used while roaming outside of your
home area, or to let the network be chosen
automatically.
You can select a network other than your home
network only if there is a valid roaming agreement
between the two.
Caller ID
(Menu 9.5.5)
This network service allows you to prevent your phone
number from being displayed on the phone of the
person being called. If you select Default, the phone
will use the default setting provided by the network.
Some networks may not allow you to change this
setting.

(Menu 9.5.4)
Closed User Group
(Menu 9.5.6)
Use this menu to set incoming and outgoing calls to be
restricted to a selected user group. For details about
how to create a closed user group, contact your
service provider.
• Index List: add, delete, or activate CUG index
numbers.
• Outside Access: enable calls to numbers other
than those in the closed user group. This feature
depends on the nature of your CUG subscription.
• Default Group: enable the default CUG, if you
have set one with your service provider. When
making a call, you are given the option of using
your default CUG, instead of selecting one from the
list.
Band Selection
(Menu 9.5.7)
For the phone to make and receive phone calls, it
must register with an available network. Your phone
can handle any of the following types of networks:
GSM 1900 and Combined GSM 900/1800.
