There are a couple of different ways that Mobile Phone bugs can be used. There are fairly inexpensive low tech Mobile Phone bugs, and there are more expensive and much more rewarding, devices that can be used to hear what you need to hear, but that others might try to keep from you.
The first category of Mobile Phone bugs is not really a Mobile Phone at all. It merely looks like a Mobile Phone. It can receive calls, and it will call you automatically, but this phone is not meant to be carried with you. This bug is meant to be “forgotten” or “charging” at the home or office. It plugs into a splitter that shares a phone jack with a regular phone. When a call is made, you can listen in to both ends of the conversation by use of your bug. The bug will even call you when the subject places a call so that you can listen in.
One of the Mobile Phone bugs that require you to take a more active role in listening is a Mobile Phone that is equipped to pick up transmissions by Mobile Phones around it. Mobile Phone calls are among the easiest to intercept, as the sound is carried on frequencies right through the air. All you have to do is be in the vicinity of your subject and then dial in to your Mobile Phone bug. It looks as though you are talking on your Mobile Phone, but really you are listening in on a conversation.
Finally, the most advanced of Mobile Phone bugs let you listen in, even if you are on the other side of the country, or even the other side of the world. This type of bug works like a regular Mobile Phone. Give it to your subject, and then you can listen in to what she or he is doing whenever you want. The phone has a standard number, that anyone can call, and a secret number that only you know. When you call the secret number, a microphone is activated and you can listen in, not only to conversations held on the phone, but also to what is going on in the same room as the Mobile Phone.
These devices are innocuous and common. They look like what everyone today has and seems to need. You cannot go wrong when you get the information you need using Mobile Phone bugs.
