THINGS YOU NEVER KNEW YOUR CELL 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:

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 (with remote) 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!"

THIRD : Hidden Battery Power
Imagine your cell battery is very low. To activate, press the keys
*3370# your cell will rest art with this reserve and the instrument will
show a 50% increase in battery. This reserve will get charged when you
charge your cell next time.

FOURTH: 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 #. A 15 digit code will appear on the screen.
This number is unique to your handset. Write it down and keep it
somewhere safe. When your phone gets stolen, you can phone your service
provider and give them this code. The y 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
does this, there would be no point in people stealing mobile phones.

And Finally....FIFTH:
Cell phone companies are charging us $1.00 to $1.75 or more for 411
information calls when they don't have to. Most of us do not carry a
telephone directory in our vehicle, which makes&nbs p;this situation even more
of a problem. When you need to use the 411 information option, simply
dial: (800) FREE 411, or (800) 373-3411 without incurring any charge at
all. Program this into your cell phone now.

This is the kind of information people don't mind receiving, so pass it
on to your family and friends.
