Just so no one confuses what I meant: In the USA, if there is any service in your area of country... all you have to do is turn a cell phone ON and it is required to be able to call 911 (assuming the phone isn't defective.) No plans, no agreements nothing... This was enabled, orginally for women in distress, abused women who were destitute but needed some way to always call for help. It has become a nation-wide service backed by law or statute
