If you want to be able to listen in to what is happening inside a room from some distance away and need something to blend into the environment, then the GSM 4 or 6 Gang Extension Plug Bug may be just the solution to suit your needs.

Auto-Answering GSM Bug – Fully Functional Sockets

This product is essentially an all new 4G GSM module and microphone all wrapped up in the innocent guise of a fully functional, 4 or 6 gang plug extension lead. The GSM 4/6 Gang Plug Bug can be simply plugged into any mains socket available to remain permanently powered, ready for dial in anytime, anywhere. The SIM card concealed within the unit can be called from any phone. The Plug Bug will not make any noise or give any indication as to what is happening, but will auto-answer the call and open up the very sensitive microphone that will allow you to hear what is going on around it.

Blends Into The Environment – Super Sensitive Microphone

The in-built microphone is sensitive enough to pick up normal speech level noise within a radius of up to 6 metres of this GSM Bug. This means that even if the Plug Bug was under a desk tucked away, it would still easily pick up on sounds in the room where it is placed. The device is powered from the mains supply, so as long as it is connected to a ‘live’ mains outlet then the unit will, within a minute, be ready to receive your call. All of the sockets on the Plug Bug extension work, which means that numerous other mains powered devices can be plugged in and thereby completely put this GSM extension Bug ‘above suspicion’.

Listen in From Afar

There is no limitation on the distance from which you can call the device because in reality it is just like calling another mobile phone. You will not need any credit on the SIM card within the unit to be able to listen-in (some charges may apply if you call in from an international phone). It is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network. The alternative is to use a low cost contract SIM so there will be no issues with disconnection as long as the bill is paid up to date.

Ideal for Home, Office or Workshop – Changeable Network SIM

If you are looking for the ideal listening device to be able to place into a room without drawing attention then this 4 or 6 Gang extension GSM unit has to be an obvious choice. An extension lead of this type will never look out of place at home, in the office or even in a workshop, especially because it can be used to power other devices and it can be hidden from view and still be effective as a listening bug. It should be noted that although we always supply an operational EE SIM card (Pre-pay with no credit) ready to deploy, the SIM inside the device can be changed to one of your choice to suit your budget or the network capability where the bug is to be placed.

Will this work as a standard 4-way or 6-way mains plug adapter?

Yes, it will power devices plugged into it whilst working as a listening device.

How sensitive is the microphone?

The microphone should easily pick up sounds in an 8 metre radius or more in a quiet environment.

Do all of the sockets work or is one blanked off?

All of the sockets work in the normal manner.

Will the GSM bug still work if it is unplugged from the mains power supply?

No, the unit has no back up battery, so you will not be able to listen in when disconnected.

Does it come supplied with a SIM card?

Yes, we normally supply with an EE SIM card, but this can be easily changed over when you receive the GSM unit if required.

Does the GSM Bug make any noise or are there any indication that it is being used as a listening device?

There are no giveaway signs whatsoever.

Will I need credit on the SIM card?

The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network.

You will need to consider the following to use this equipment:

  • You will need a working phone (mobile or landline) to enable you to listen in to the bug.
  • If the supplied EE SIM card then you will require a Philips type screwdriver to open up the extension lead to access the SIM card inside.
  • This unit is NOT battery powered and must be plugged into a mains power outlet that is switched on.
  • The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network.
