Most items of the Operator Services menu (e.g. Service
numbers, Services +) are subscription-dependent and
specific to operators: your mobile phone readily
supports them if they are included in your subscription.
Consequently, the menus shown following may or may
not be available. Contact your network operator for
detailed information on availability and rates.

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.

Some phone services (such as phone answering machines
and pagers) require your phone to transmit DTMF tones
(Dual Tone Multi Frequency), also known as “touch
tones”. These are used to communicate passwords,
callback numbers, caller choices, and so on.
You can send DTMF tones at any time during a call by
pressing any of the keys

You can also attach a DTMF sequence to a phone
number before dialling it (or storing it in the

Phonebook

). The phone number and the DTMF part

must be separated by a wait character.

p

 for a pause.

The phone always interprets the first pause character as
a wait character. When you dial a number containing
a wait character, your phone dials the first part (the
phone number) and then waits for the call to be
