1) Emergency number
The Emergency Number world-wide for Mobile is 112. If you find yourself out of coverage area of your mobile network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you, and interestingly... this number 112 can be dialed even while the keypad is locked. Try it out.
2) Locked the keys in the car? Your car has remote keys?
This may come in handy someday. Good reason to own a cell phone also. If you lock your keys in the car and the spare keys are at home, call someone on your cell phone. Hold your cell phone about a foot from your car door and have the other person at your home press the unlock button, holding it near the phone on their end. Your car will unlock. That saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other "remote" for your car, you can unlock
the doors (or the trunk).
Editor's Note: *It works fine! We tried it out and it unlocked our car over
a cell phone!
