4 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:

FIRST                                         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.



Also in   Australia, the Australian emergency number 000 can be dialled whilst your mobile phone keyboard is locked.  This is another reason why 000 receives so many false emergency calls!


SECOND                  Have you locked your keys in the car?
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 mobile 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. 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).
Editor's Note: It works fine! We tried it out and it unlocked our car over a mobile phone!"

THIRD                           Hidden   Battery   Power
Imagine your mobile battery is very low. To activate, press the keys *3370# Your mobile will restart with this reserve and the instrument will show a 50% increase in battery. This reserve will get charged when you charge your mobile next time.

FOURTH          How to disable a STOLEN mobile phone?
To check your Mobile phone's serial number, key in the following digits on your phone!:  

star-hash-zero-six-hash

* # 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. 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.



Not only the above, but also in   Australia   your stolen phone is added to a "Stolen Mobile Phone" database, so if your phone is found later on it can be returned to you.

Don't know about #2 and #3, they seem less likely but #1 and #4 I certainly knew about. The serial number you get back is the IMEI number, which is unique to each handset and the police and mobile companies have already made services available to report loss against this number AFAIK.

#1 & #4 certainly do - #2 sounds very unlikely (telephone signals taper off are only sampled at 8KHz I think so unable to transmit ultrasound) and #3, as well as sounding plain stupid, doesn't, at least on my Nokia!

#1 is the European emergency number. All mobile phones will dial 999, 911 and 112 with key lock on.

#2 is Rubbish. Key fobs work at FM frequencies which are digital. All speakers are analog. Although, digital speakers are being developed.

#3 Partially true. Some older mobile phones needed a power supply to keep the memory. So they keep a reserve of power to keep the memory. A lot of modern lit-ion batteries have to keep a partial charge. If they go completely dead, you cannot recharge them unless you own an arc welder and feeling brave.

#4 True
