Closed user group
(Menu 9.5.7)
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 (CUG), 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 9.5.8)
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.
The country where you purchased your phone
determines the default band that it uses. When you
travel abroad, you may need to change to an
appropriate band.
Security
(Menu 9.6)
Use this menu to protect the phone against
unauthorised use by managing the several access
codes of your phone and SIM card.
PIN check
(Menu 9.6.1)
The 4- to 8-digit PIN (Personal Identification Number)
protects your SIM card against unauthorised use.
When this feature is enabled, the phone requires your
PIN each time it is switched on.
If you enter an incorrect PIN/PIN2 three times in
succession, the SIM card is blocked. To unblock it
you need to enter your PUK/PUK2 (Personal
Unblocking Key). The codes are supplied by your
service provider.
