Most items of the Operator Services menu (e.g. Service
numbers, Se) are subscription-dependent and
specific to operators: your mobile phone readily sup-
ports them if they are included in your subscription.
Consequently, the menus shown opposite may or may
not be available. Contact your network operator for
detailed information on availability and rates.
The services provided may involve making a phone call
or sending a SMS for which you may be charged.
The phone supports standard GSM strings that can be
sent from the keypad to the network and used to acti-
vate services provided by the network.

chines and pagers) require your phone to transmit

known as “touch tones”. These are used to communi-
cate passwords, callback numbers, caller choices, and
