Our friend Kathy in Orlando sent this.. I tried #3 and it works. It's good to keep that info!-
For all the folks with cell phones. There are a few things that can be done in times of grave emergencies.
Check out the things that you can do with it:
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 (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.
THIRD (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.If your phone is 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.
