Emergency calls
Your phone supports international

and 911. You can normally use these
numbers to make emergency calls in
any country, with or without the SIM
card inserted, if you are in range of a
3G (UMTS) or GSM 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.
