These handy (if obscure) mobile phone tips actually work.
Something to learn about...
There are a few things that can be done in times of emergencies.
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, 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.
Emergency II
Have you locked your keys in the car? Does your 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, Amazing but it's true!
Emergency III
Hidden Battery power
Imagine your cell battery is very low, you are expecting an
important call and you don't have a charger.
Some instruments (i.e. Nokia, etc.) come 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.

Emergency IV
How to disable a lost 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.
If your phone gets lost, you can phone your service
provider and give them this code.
They will then be able to block your handset so even if the SIM card is changed, your phone will be totally useless.
