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.
Locked your keys in the car?
If you lock your keys in the car, 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.
Hidden Battery Power
Imagine your cell battery is very low. To activate, press the keys *3370#. Your cell phone will restart with its reserve power and the instrument will show a 50% increase in battery. This reserve will get charged when you charge your cell phone next time.
Disable a stolen mobile phone
To check your Mobile phone's serial number, press *#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.
