The text below is a snippet from a blog called Pause At Work
There are a few things that can be done in times of grave emergencies.
Your mobile phone can actually be a life saver or an emergency tool for
survival. Check out the things that you can do with it:
The Emergency Number worldwide 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 if the keypad is locked. **Try it out.**
Subject: Have you locked your keys in the car? Does you car have remote
This may come in handy someday. Good reason to own a cell phone:
If you lock your keys in the car and the spare keys are at home, call
someone at home on their cell phone from your cell phone.
Hold your cell phone about a foot from your car door and have the person
at your home press the unlock button, holding it near the mobile phone on
their end. Your car will unlock. 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!"*
