You can call the emergency number if there is no
credit on your phone.
If the signal is weak, try another location to make or
continue with a call, e.g. when indoors move towards
a window. Reception is often poor in elevators, tun-
nels or underground railways and car parks.
If you want withhold your phone telephone number,
use the main menu under Call settings/ Send own
number. (This network service may not be available)
Slide the switch on the right hand side of the phone
upwards in the direction of the "open lock" symbol
.
A number for the short message service usually
stored on the SIM card by the operator and should
not need to be entered or changed.
Charges start when a call connects to a person or an
answering machine. There is no charge for writing or
receiving an SMS, only when sending an SMS, and
none for using phone features e.g. alarm clock.
If your SMS is in the SMS Outbox then it was OK, or
you can get confirmation after the SMS is delivered –
contact your operator for details.
