Emergency calls
Your phone supports international
emergency numbers, for example, 112
or 911. You can normally use these
numbers to make emergency calls in
any country, with or without the SIM
card inserted, if you are within range of
a network.
In some countries, other emergency
numbers may also be promoted. Your
network operator may therefore have
saved additional local emergency
numbers on the SIM card.
To make an emergency call
• From standby enter 112 (the
international emergency number) and
press .
To view your local emergency
numbers
