HOW SPY BUGS WORK: Operating a GSM Audio Bug, as easy as one, two, three?

Updated on November 8, 2011

The following three points highlight the alarming simplicity of these devices, illustrating the importance of employing specialised counter surveillance SWEEP SERVICES as defence measure.

1 Buy a bug, from $7-$500 there is no shortage of them on the web.

2 Insert the SIM card into the device. The 2-Way GSM Audio Listening Device is a remote-listening spy device that records the sound around it and can be dialled into using any mobile phone.

3 TWO WAY GSM audio listening devices come with two setting options:

SOUND ACTIVATION. Meaning that if there is a sound above a certain level within the target area where the bug has been placed the sound is picked up by the microphone activating an auto call function that dials your number. This makes it possible to hear all the sound in your selected location without having to constantly dial in to check.

DIAL IN. Simple dial the SIM card’s number from any phone, anywhere in the world, the device auto answers the call allowing the listener to hear what’s happening within the immediate vicinity of the bugging device.

Shockingly simple isn’t it? No skills needed, no training and no real costs.

Still not convinced ?


In summary although modern spy shop type technology such as those described above do represent a very real threat. they represent low level domestic spy tech often used by the non professional ‘buggiest’. There are multiple levels of clandestine listening and recording devices far more complex in design and function that are employed by the professional intent on compromising your privacy. Defending against GSM bugs and high level clandestine devices requires the procurement of dedicated highly specialised services.

Taking The Next Step:

Concerned that your personal or private business dealing may be under surveillance. Please feel free to contact us directly. If calling, we suggest you do this away from the area of concern, ideally use a public pay phone. If this is not possible, in general GSM mobiles can be considered safe unless your perceived threat level is extremely high.
