Make an Emergency Phone Call
You can use the phone to make an emergency phone call, even if the SIM card is
missing from your UMTS phone or if you do not have a valid CDMA account. In
either case, the phone shows that you have no service. However, if you dial certain
emergency numbers (such as 112, 911, 000, 08, 118, 119, or 999) the call will go
through.
