Cell Phone Stuff i never knew..well sorta didn't know...

Emergency

THE CLAIM: 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.

THE FACTS: Calling 112 on your cell phone will (in some parts of the world, primarily Europe) connect you to local emergency services, even if you are outside your provider's service area (i.e., even if you are not authorized to relay signals through the cell tower that handles your call), and many cell phones allow the user to place 112 calls even if the phone lacks a SIM card or its keypad is locked. However, the 112 number does not have (as is sometimes claimed) special properties that enable callers to use it in areas where all cellular signals are blocked (or otherwise unavailable).


Have you locked your keys in the car?

THE CLAIM: 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 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).

THE FACTS: Cars with remote keyless entry (RKE) systems cannot be unlocked by relaying a key fob transmitter signal via a cellular telephone. RKE systems and cell phones utilize different types of signals and transmit them at different frequencies.


Hidden Battery Power

THE CLAIM: Imagine your cell battery is very low. To activate, press the keys *3370#

Your cell 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 next time.


THE FACTS: The claim that pressing the sequence *3370# will unleash "hidden battery power" in a cell phone seems to be a misunderstanding of an option available on some brands of cell phone (such as Nokia) for Half Rate Codec, which provides about 30% more talk time on a battery charge at the expense of lower sound quality. However, this option is enabled by pressing the sequence *#4720# — the sequence *3370# actually enables Enhanced Full Rate Codec, which provides better sound quality at the expense of shorter battery life.
