I know a friend of my father's who works at the Hungarian Internal Affairs Buraeu (sort of like the FBI in Hungary) who once told my father in confidence that they've, on numerous occasions, actually listened in on cellular phones while they were on.

I other words, they've tapped into a cell phone on the network and listened in not on the conversation but on the surroundings. There was no active conversation.

Additionally, he told my father that even if the cell phone was off they could do this. The only way to really secure the phone is by taking out the battery.

So my question is, how plausable would the existence of this sort of exploitation be here in the United States?

I know that I don't say anything of importance around cell phones.

I've always thought of cell phones as our own little personal electronic tracking device that we have to pay lots of money for....

I wouldn't be surprised if they listened in on conversations, because anyone can do it with a scanner, i believe. About listening to things when they are off, i'm not sure if that is even possible.

I think that the Government Agencies would be doing it on occasion, mostly likely on those who they are investigating. Government Agencies I believe would be most apt to monitor all communications on their subject. I think also that they may just do it to extract intelligence about people or organizations.

Scanners that are digital can monitor cell phone conversations with ease. In my opinion, people should hold the belief that their conversations over cell phones are being monitored by somebody.

The scary part, though, is not that they can listen in on an active conversation in progress on the cell phone network, but they can also activate the microphone on an idle cell phone and listen in on the surroundings...

I wouldn't be supprised if they listened in, switching on remotely is possible though, the same way that networked computers can switch each other on if configured properly, The only way to avoid this sort of stuff is to not use a mobile phone, or a normal phone either, if your that worried about it.

It is possible to purchase a device to do just that, but it will set you back a grand at least. Their use is highly frowned upon in the U.S. since jamming a phone frequency violates FCC regulations. If you are really interested, just google for the things and you can find them.

I agree that mobile/cell phones can be extremely annoying and
ppl are sometimes arrogant when they choose to use them.
Hehe, it would be kinda' cool to have a pocket sized device to
'jam' fone's within a certain radius...BUT I wouldn't want to get
caught with it. After 9-11 the authority's would be all over u
if say, they happened to trace 'the jammer' u purchased online
or even in person and pay CC or cheque at Radio Shack.

If I knew "someone" was listening in on my phone conversations, I would be tempted to be really outrageous!

All I can say is good luck to them if they have nothing better to do! Other people's conversations are so boring.

As for listening to the background noises of phones not in use - feel free to listen to the traffic noises from mine all day long!

Found on a website(rather outdated):

All you need to know to monitor Cell Phones

--------------------------------------------------------------------------------

First off I would like to tell you that listening to any wireless phone conversation is now illegal. New laws were passes back in the 90's to keep manufactures from making and selling scanners capable of receiving the cellular band. I don't care what you have been told, it is illegal to listen to ANY phone call. It's quite legal to own a cell capable scanner which was made before the laws were passed but it's illegal to listen to cellular phone calls. Two totally different things. Its kind of like owning a legal gun, but it's illegal to kill someone just cause you want to.

Ok, down to the good stuff! First off you need to know that analogue cell calls are in the 869.040 to 893.970 MHz range. This is the tower side of the conversation. The actual cell phones transmit in the 824.040 to 848.970 MHz range. There is a 45 MHz split in the phone and the tower. You can hear the tower side for about 5 square miles and the phone itself for only about a mile or two at best. Lets say you were using a frequency counter and someone walks by you talking on a cell phone. Your frequency counter would show something like 824.600 MHz. You can add 45 Mhz to this and listen to the tower side of the conversation which usually has both sides of the conversation at 869.600 MHz.

Some scanners pick up cell phone conversation in other parts of the band. This is known as "imaging" and most dual conversion scanners will pick up images 21.7 Mhz above or below the actual frequencies. Lets say you have a cell blocked scanner but your picking up calls at 901.690 MHz. If you minus 21.7 MHz away you would get 879.990 MHz. This is where the real conversation is taking place. Triple conversion scanners have better front ends and eliminate most "imaging". There are some out there that do pick up images in the 1100 to 1200 MHz region like the PRO-2035.

If a person is traveling down the road, the phone will switch from cell site to cell site as the signals weakens and they get closer to the next tower. You will have to stay close to them with a frequency counter to keep getting the frequency as the phone switches or you can get a Oki-900 cell phone and a CTEK cable and trunk track them. That's right, follow the calls instantly as they change from site to site. I would not suggest getting caught with one of these because its VERY illegal and it could end you up in prison with bend over Billy as a cell mate! You can also get a Optoelectronics Scout frequency counter and a AOR-8200 scanner (unblocked from Canada or Europe) to track cell calls. The Reaction tune cable lets the Scout lock onto any frequency and tune the scanner to that frequency instantly! The only difference with it from the Oki/CTEK combo is that the Scout/AOR will follow the actual cell phone side and you have to stay close to the phone so that the counter can monitor the RF signal. If you really want to follow the calls, go with the CTEK and Oki combo! Please do not email me asking about where and how to buy this stuff. If you follow the links and do some reading, you will figure it out. Building a CTEK cable is not for the week hearted! You MUST have excellent soldering skills. If you are not sure about building the CTEK cable then just go out and buy a older scanner that was made before the laws were passed and listen to them like most other people do. You can still get new unblocked scanners but you have to take a small risk. Most countries out of the USA sells unlocked scanners. Places like Javiation over in the UK. I have heard many, many good thing about this company and success stories of people ordering unblocked scanners and having no problems getting it. Lets face it folks, the government is more worried about terrorism right now than you listening in on a perverted cell phone conversation. If you purchase one, use your VISA or Master Card. If by chance Federal Customs caught the scanner, play dumb! Your credit card company will probably refund your purchase. I have never heard of anyone getting fined for importing one scanner. Now if you tried to buy 20 or 30 of them to resell and they caught it then you might face some men in black at your front door.

Some of you are probably wondering about digital cell phones? I know of NO scanner as of now that will let you listen to them but here is a interesting article that looks promising! Trust me, there are a crap load of analogue cell phones out there (over 70 million). You will have more to listen to than you can handle. In most big cities, you can find many conversations at any hour of the day or night.

The most important thing is this: If you DO decide to listen in on a phone call, keep your mouth shut about what you hear! Do not go around bragging about it and telling secrets you heard. Not all people appreciate the fact that you can listen in on calls! Shut up and enjoy.
