Random life-saving tip: The EMERGENCY number worldwide for mobile networks is 112. Even if you are outside your coverage area, you can dial 112, and your phone will search ANY existing network in order establish a connection to local emergency personnel. You can even do this if the keyboard is locked. Try it out for yourself!
