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.This 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).
THIRD
Hidden Battery Power
Imagine your cell battery is very low. 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.
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 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.
FIFTH
Free Directory Service for Cells
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 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.
The New York Herald Sun 
#1 = True for GSM.
#2 = HORSESHIT. Cell phones don’t transmit RF.
#3 = HORSESHIT. There is no “hidden reserve” – that key combo might change the transmission power on a single Nokia, but it’s by no means universal.
#4 = Partial horseshit, that keycode is for a single handset brand. Get your IMEI from under the battery.
#5 = HORSESHIT. Cell phone companies still charge for airtime!
3 horseshit, one partial, and only one true.
NUMBER FIVE IS TRUE:

NUMBER FOUR:
get the “IMEI”number from UNDER THE BATTERY…
NUMBER THREE:
On more and more phones the number 4720 will unlock what is commonly referred to as HRC or “half – rate codec” which will get one about twenty to thirty per cent more battery life.
NUMBER ONE:
112 is the Europe-wide emergency number. Even though 999 is the standard emergency number here, 112 will connect you as well.
All phones sold there allow you to dial 999 or 112 even if the keypad is locked, and it will connect to any network within range; even an unregistered handset will allow you to dial these numbers.
*#06# Equals IMEI number, which disables the handset
Not gonna kill myself either mate….
I haven’t tried the power issue or the unlock your vehicle, but the other two work.
Thanks TJ!
for anyone saying that #2 doesnt work, well it does, they tested it on Brainiac: Science Abuse last year, and it worked
These seem very iffy but here is another one. Store a old bag phone or cell phone in your car. Even if it has no account number and is totally inactive it can still be used to make emergency calls. The trick is you have to be able to plug it into the car as the battery will be dead after sitting a long time.
Great idea Allan!!
Brilliant….
