Emergency calls
Your phone supports international
emergency numbers, for example, 112
and 911. These numbers can 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.
