your default CUG, instead of selecting one from the
list.

default group is enabled or a CUG index is
selected.
Band selection
(Menu 3.7)
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 1800 and Combined GSM 850/1900.
The country where you purchased your phone
determines the default band that it uses. When you

appropriate band.
When you select a new band, your phone
automatically searches for all available networks. Your
phone registers with a preferred network within the
band.
