Things you may not know about your cell phone

THINGS YOU NEVER KNEW YOUR CELL 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 Subject: 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.

SECOND Subject: 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 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 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).

THIRD Subject: Hidden Battery Power 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.

FOURTH 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 # 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 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 does this, there would be no point in people stealing mobile phones.

FIFTH Cell phone companies are charging us $1.00 to $1.75 or more for
411 information calls when they don't have to. Most of us do not carry a telephone directory in our vehicle, which makes this situation even more of a problem. When you need to use the 411 information option, simply
dial: (800) FREE 411, or (800) 373-3411 without incurring any charge at all. Program this into your cellphone.

Cool information Joe, Thanks for sharing.

The one I like the most is the "*3370#" regarding battery life. That is pretty cool

I think I know that one.

WTF is up with the car unlocking one?

How does that work?

Sound wave is the same so sending it through the phone would be the same effect as standing right next to it. Very cool idea.

It probably isn't sound wave.

Has anyone tried any of these?

I just tried the fourth one, and a code did appear on the screen (though mine is 17 digits instead of 15).

I'd love to know if someone tries the second one.

Very interesting, JWR. Thanks for sharing!

Damn do I feel dumb. I meant to say radio frequence ~_~'. Must be having an off day.

Yeah, we tested the radio frequency idea with car keys in my physics class. However, not all remote car keys use radio frequencies, so this does not apply to all remote keys. Most of them, but not all of them.

Thanks for all the tips though, I had no idea about the rest of them.

RoboFlonne · Post by **RoboFlonne** » Thu Feb 22, 2007 10:41 pm

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, thus this is just a Urban legend and untrue.

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 the HALF RATE CODEC, which provides about 30% more talk time on a battery charge at the expense of lower sound quality. However that option is enabled by the sequence *#4720# and not *3370#. *3370# actually shortens battery life for higher quality sound.

One day people will no longer need cars.

Wow, I learned a lot about my cell phone today. Thanks for the tips!

Some interesting tips there actually, some I've not heard of, but am eager to try.

In regards to Tip 4, that is just the IMEI number, which is usually on the box, receipt and displayed behind the battery anyway. You can indeed blacklist the handset, but usually that blacklisting only applies to the country of origin, which is why thieves usually sell their stolen handset abroad.

Tip 2 is actually quite interesting too, I actually watched this programme called Brainiacs a few days ago where they tested to see whether it actually worked and it did, I'm not convinced myself which is why I need to get round to trying it! I would be surprised if it did though!
