For details about how to create 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.
If you select the Closed User Group menu, you can enter
the CUG function. You can now access the following
options:
• Index List: lets you list, add, or delete CUG index numbers.
If there is no CUG index stored, you are prompted to add a new
index when you select this option. Once you have added a CUG
index, the list of current CUG indexes appears.
Add a new CUG index as advised by your service provider, or
delete a group.
• Outside Access: lets you enable or disable calls to numbers
other than those in the CUG. This feature depends on the nature
of your CUG subscription. Please check with your service
provider.
• Default Group: you may set a default CUG with your service
provider. If you have done so, you can enable the Default
Group option on your phone. When making a call, you are give
the option of using your default CUG, instead of selecting one
from the list.

For the phone to make and receive phone calls, it must

handle any of the following types of networks:
• GSM 1800
