FOUR THINGS YOU PROBABLY NEVER KNEW YOUR MOBILE PHONE COULD DO!
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:
Emergency
The Emergency Number worldwide  for all Mobile Phones is 112. If you find yourself out of the coverage area of  your mobile network and there is an emergency, dial 112 and your mobile will  search any existing network in your area to establish the emergency number for  you, and interestingly this number 112 can be dialled even if the keypad is  locked. This works on all phones worldwide and is free. It is the equivalent of  000.
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 mobile 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 thousands 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: I didn’t believe this when I heard about it! I rang my  daughter in Sydney from Perth when we went on holiday. She had the spare car  key. We tried it out and it unlocked our car over a mobile phone!'  
Hidden Battery Power
To activate, press the keys *3370#  (remember the asterisk). Do this when the phone is almost dead.
Your mobile  will restart in a special way with this new reserve and the instrument will show  a 50%
increase in battery life. This reserve will get re charged when you  charge your mobile next time. 
This secret is in the fine print in most phone  manuals. Most people however skip this information without realising.
How  to disable a STOLEN mobile phone?
To check your Mobile phone's serial number,  key in the following digits on your phone: * # 0 6 #Ensure you put an asterisk  BEFORE the #06# sequence.
A 15 digit code will appear on the screen. This  number is unique to your handset. Write it down and keep it somewhere safe. If  your phone ever get stolen, you can phone your service provider and give them  this code. They will then be able to block your handset so even if the thief  changes the SIM card, your phone will be totally useless. You probably won't get  your phone back,
but at least you know that whoever stole it can't use/sell  it either. If everybody done this, there would be no point in people stealing  mobile phones.. "This secret is also in the fine print of most mobile phone  manuals. It was created for the very purpose of trying to prevent phones from  being stolen.""
