Some little-known uses for cellphones

Thanks, James in Oz, for sending the following info.

If you wrap your cellphone with aluminum foil you can’t get a call on it, so we presume it also disables hte CIA’s tracking device inside, which works even when you remove the battery, evidently. I think this bears repeating from time to time but we shouldn’t be Luddite chumps and despise this technology. Here are some good reasons why:


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:


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 dialed even
if the keypad is locked. This works on all phones worldwide and is free. It is the equivalent of 000.

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 thousands 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: I didn’t believe this when I heard about it! I rang my daughter in Sydney from Perth when we went on holiday. She had the spare car key. We tried it out and it unlocked our car over a mobile phone!’

Hidden Battery Power

To activate, press the keys *3370# (remember the asterisk). Do this when the phone is almost dead.
Your mobile will restart in a special way with this new reserve and the instrument will show a 50%
increase in battery life. This reserve will get re charged when you charge your mobile next time.
This secret is in the fine print in most phone manuals. Most people however skip this information without realizing.

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 done 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.

Also -ATM PIN Number Reversal – Good to Know!!

If you should ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your PIN # in reverse. For example, if your pin number is 1234, then you would put in 4321. The ATM system recognizes that your PIN number is backwards from the ATM card you placed in the machine. The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to the location.
All ATM’s carry this emergency sequencer by law.

This information was recently broadcast on by Crime Stoppers however it is seldom used because people just don’t know about it.

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

My “smart” phone won’t do this. If I enter these numbers it wants to call them, that’s all. If you call them you get nothing.

What am I doing wrong?

My PIN number is a palindrome, do the cops get called everytime I use my card? :O)


one reason a cel-phone with its battery removed can still track you is this:

wired directly onto the circuit boards will be a little rechargeable battery, similar if not identical to the CMOS-battery on your computer’s motherboard which powers the BIOS. this is why, after you’ve unplugged & moved your desktop computer, it still knows the time when you plug it back in, even though it “didn’t have power”

a drip of voltage small enough to power a timer-chip could, i’d imagine, also power a transponder-chip, or whatever gadgetry it is theyre stashing in your phone

i’ve torn apart all kinds of computers & phones, & i’m 100% on this little factoid

I waited till the battery icon was totally empty on my Samsung phone and keyed in *3370# but nothing happened.

Are we supposed to turn the phone off after entering this code or do we press the ‘dial’ button because keying this code into my phone does nothing.
I’ll try on my Nokia phone later.

I’ve only tried the fourth option so far and it worked without a hitch.
