Emergency calls
Your phone supports international
emergency numbers, for example,

normally be used to make emergency
calls in any country, with or without
the SIM card inserted, if a 3G (UMTS)
or GSM network is within range.
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.
