just writting anything that comes by and i think is interesting

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. 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 phone 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 phone next time.( some countrys #4720# )

FOURTH How to disable a STOLEN mobile phone?

To check your Mobile phone's serial number, key in the following
Digits on your phone: *#06#. 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)FREE411, or (800) 373-3411 without incurring any charge at all. Program this into your cell phone now
