Supplementary network services
Closed user group
This is a network feature by which the use of your
telephone is restricted to certain phone numbers
within a group defined by the network operator
and the owner of the SIM card. You may be a
member of different groups. Each group has its
own ID number. The network defines which
group is your default user group. You have the
option of calling outside the group – perhaps at a
higher charge. Contact your network operator for
further information.
Unstructured supplementary services (USSD)
On some networks you have the possibility of
sending unstructured supplementary service
strings. An USSD service string should always be
terminated by pressing the
-key. Contact your
network operator for further details.
In order to be able to send USSD service strings
you must enter the Phone setup menu and select
Speed dialling off . Pressing the relevant
keys 0 to 9 for one second will lead you to the
alpha mode enabling you to enter letters and di-
gits instead of only digits.
