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: -
*EMERGENCY*


*I*


* The Emergency Number worldwide for **Mobile** is 112 .* If you find
yourself out of 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.**


*II*

* Subject: Have you locked your keys in the car? Does you car have remote keys?*


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).
Editor's Note: *It works fine! We tried it out and it unlocked our car over a cell phone!"*



*III*



Subject: Hidden Battery power



Imagine your cell battery is very low , you are expecting an important call
and you don't have a charger. Nokia instrument comes with a reserve
battery. 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.
AND


*IV*



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 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
 
Unlocking your car via your cellphone DOES work. My wife and I tried it out a few weeks ago. It took a few minutes to find the "sweet spot" to make it open but it did work. Snopes got that one wrong.

She started clicking the remote constantly right up into the mouthpiece. I was moving the phone around the Jeep at about 1-2 feet away.

She was 3 miles away in our house. I was at the liquor store picking up some more Maker's Mark. :D :thumbup:
 
You've got to be kidding ... what kind of remote does this car of yours have ? All that I've seen so far are either IR or RF (in one of the ISM bands) and cell phones can't retransmit either.

In other words: if your remote transmits a sequence of IR flashes to unlock there is no way in hell that somebody else's cell phone would pick up the IR pulse train from the remote, encode it into audio, transmit it to another phone and that phone decode it and send the relevant sequence to the receiver that unlocks the door - way too many ifs for something like this to work. Ditto (and even more so) for RF remotes.

For something as absurd as this to work the remote would have to use AF which would be just unfeasable as sounds of sorroundings would prevent reliable operation (some Polar watches use AF to transmit data to computer IIRC; I've been told that this method is extremely unrealiable) ... at least not over here on this side of the pond.
 
For free phone number information dial: 1(800)free-411. You'll get annoying advertising but you'll also get free dialing assistance.

I don't think they did. I think the technology they were using was older. That info on snopes has been up a while.

Yeah ... your "pancakes" - what's up with those ? I'm sure they come in handy when you need to pad that rocking desk in your kitchen but that's it :D

Seriously thouh, I don't claim to have seen every single car remote in existence but I design electronics for living (which includes reverse-engineering and repliacting functionality of such remotes ...) and there is no reason on Earth why something as silly as that should ever work. No manufacturer is stupid enough to use audio for any kind of communication between remote and the lock, simply because there's waaaaaaaaaaaay too much "interference" around, an accidental instance of which could trigger opening of the lock.

Besides, why would the designers of that car's remote (un)locking system complicate their life with something as silly as that when IR and RF technology has been widely avaliable for decades, is easy to implement and offers plenty of wiggling room for each particular company's "standards"; company A can easily devise a protocol that is unlikely to be matched by a protocol of company B, even if they're using same technology, same means of transmission, same modulation technique, same modualtion frequency (that's how TV remotes operate - a NEC IR remote uses 38 KHz modulation, as does Nokia's, but they aren't compatible between one another - NEC's remote won't be able to operate your Nokia's TV, unless it supprots same protocol).
 
I too have used a cell phone to unlock my car. I held the phone up, dialed my home, asked my wife to bring my spare key and voila, unlocked. BTW, it was a Subaru Outback, also worked with my BMW R100RT.
 
Ive never unlocked a car woith a cellphone but they showed it working on Brainiacs on Sky a few weeks ago. I cant figure out how it works but it certainly did for them and if you guys have got it working too I guess it must work at least on some cars. Who knows how though. Like Faramir said theyre RF not audio frequencies
 
I used to leave my cellphone next to the radio while I was working. For some reason I could always hear it ring, no matter how loud the radio was. I realized that everytime the phone would ring, it would squelch the station so there was no sound. Who knows. Obviously a lot more going on with the phones than you would think.
 
i think it is quite possible that the reason you can do this has to do with piggybacking transmitions just like how you can talk on weak cheapo walkie talkies over long distances by being close to a more powerful transmitor
 
Any Cal,

I've noticed the same thing with my cell phone, except I've had it happen on radio speakers, laptop speakers and my tv's speakers.
