Emergency number (SOS)
By pressing the soft key
make an emergency call on any network
without a SIM card and without entering a
PIN . This must only be used in real
emergencies.
Network connection
Strength of the incoming signal.
A weak signal reduces the call
quality and may lead to loss of
connection. In this case, change
your location.
Do not interfere with the antenna at the top
of the phone unnecessarily during
operation, otherwise the quality of the
connection may be impaired.
If you are outside your "home network",
your phone automatically selects another
GSM network (see also p. 61).
SIM services
This symbol is displayed if your
SIM card supports special
