Can you really do that with a Mobile Phone?

Hi Everyone,

THINGS YOU NEVER KNEW YOUR CELLPHONE 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

*I*

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, dial112and 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.**

*II*

Subject: Have you locked your keys in the car? Does you car have remote keys?

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!"*

*III*

Subject: Hidden Batterypower
Imagine your cell battery isvery low, you are expecting animportant call and you don't have a charger.Nokia instrument comes with a reserve battery.To activate, press the keys *3370# Your cell will restart 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.

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 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 does this, there would be no point in people stealing mobile phones.
