THINGS YOU PROBABLY NEVER KNEW YOUR MOBILE PHONE 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
The Emergency Number worldwide for all Mobile Phones is 112. If you find yourself out of the coverage area of your mobile network and there is an emergency, dial 112 and your mobile will search any existing network in your area to establish the emergency number for you, and interestingly this number 112 can be dialled even if the keypad is locked. This works on all phones worldwide and is free. It is the equivalent of 999.

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 # Ensure you put an asterisk BEFORE the #06# sequence. 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 ever gets 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 did this, there would be no point in people stealing mobile phones.  This secret is also in the fine print of most mobile phone manuals. It was created for the very purpose of trying to prevent phones from being stolen.  Please pass this along to everyone.   This is the kind of information people don't mind receiving, so pass it on to your family and friends
