if you have a nokia phone (most of them), go to the main screen, press *3001#12345# it brings you the the secret settings menu...then you can add numbers other than 911 under the menu "Emergency nos.", and then you can call them for free, even if you have no service or plan. Its pretty cool.
ill be super rich and own mt.hood and let everybody from ns ski for free... except freezed
i heard that the 911 operators are trained to read minds so even if your in the woods without a phone, you can just think of the number 911 and you can get an ambulance to rescue you. but you need some reception.
