For all the folks with cell phones, at least in the USA, don't know about other locations for some of the items.(This should be printed and kept in your car, purse, and wallet. Good information to have with you.)
 
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:
 
 FIRST :
Emergency
 
The Emergency Number worldwide for  Mobile is 112. If you find Yourself out of the 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.
 
SECOND
 
Have you locked your keys in the car?
 

Does your car have remote keyless entry? 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

How to disable a STOLEN mobile phone?
 
To check your Mobile phone's serial number, key in the following
 
Digits on your phone: *#06#. A 15-digit code will appear on the

somewhere safe.
When your phone get stolen, you can phone your service provider
and give them this code. They will then be able to block your handset
