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/region, with or without the
SIM card inserted, if a 3G (UMTS) or
GSM network is within range.
In some countries/regions, other
emergency numbers may also be
promoted. Your network operator may
therefore have saved additional local
emergency numbers on the SIM card.
