TravelingMom, Ann B., shared the following cell phone tips for saving battery, money and stolen phones:
Things you never knew your cell phone can do:
(1) 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.
(2) Hidden Battery Power. Most cell phones have a battery reserve that you can activate by pressing *3370#. If you cell phone dies, it will restart with this reserve and the instrument will show a 50% increase in battery. This reserve will get re-charged the next time you charge your phone.
(3) Cell Phone Serial Number / Stolen Cell. If your phone is stolen, your service provider can block your handset if they have the phone's serial number 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 whoever stole it can't use/sell it either. If everybody does this, there would be no point in people stealing mobile phones.
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.
(4) 411 / Information. Tired of forking out $1.00 or more for 411 information calls? Dial: (800) FREE 411, or 800) 373-3411 instead at no charge.
