You cannot make a call if the phone has no signal.
If your display says Limited Service or SOS, the phone
cannot receive a signal from your network, or has run out of
credit, so can only call the emergency number 112 (or 999).
Can an emergency
call be made without a
signal or credit?
You can call 112 (or 999) if there is no credit on your phone.
How can reception be
improved?
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, tunnels or underground
railways and car parks.
Can I suppress /
withhold my telephone
number?
If you want to withhold your phone telephone number, use

network service may not be available)

in the direction of the “open lock” symbol.
What is the SMS
service centre
number?
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.
When do I start to
incur call charges?
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.
Did I successfully send
my SMS?
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.
