Upgraded GSM Mains Socket Spy Bug is a Fully Functioning Double Mains Socket fitted with our very latest Upgraded GSM listening technology. Simply replace or fit on to 240 volts supply and monitor the room conversations from anywhere in the world. Hidden listening device bug has upgraded features including recording facility, larger aerial for better reception, more sensitive microphone for better pickup allowing you to listen to what’s happening in the room where it’s deployed, with the added facility to record audio onto your Micro SD card up to 16gb for future playback. Both functions can be operated by sending a text to the device to turn on and off. It’s like having a listening device and a voice recorder in a small box. We test & setup the device ready, so all you must do is plug it into the mains, easily fit your own sim card to listen, anytime, anywhere in the world. It really is that simple. We can fit a GSM sim card ready for use, when sim card is purchased in our store, or you can use your own GSM sim card, contract or pay as you go.

When you call the mobile number, the device will auto answer to allow you to listen to the surrounding noise. Or just send a text to record audio to the micro SD memory card you have inserted in the device. Therefore, you can either call up device to listen or record audio to the Micro SD card installed (card not included).   

Register the bug with a phone of your choice, and the bug will then call you when it hears sound above 40db in the area of use. You will be able to hear sound within a 4-meter radius of the bug.

The listening device auto-call back function (sound activation) can also alert you by calling you whenever it picks up sounds in the area. This saves you time as you don’t have to listen in unnecessarily. You can easily switch this function on or off, just by sending a SMS text to the device. This feature is great for protecting your property to monitor unwanted activity.

The device can work in automatic call back, manual ie you call up at your convenience or recording mode where it records onto a Micro SD card.

Devices are hand made to order in the UK exclusively for our customers. Unlike cheaper imports, all our products are strategically assembled to enable the microphones to pick up activity, more effectively. Beware of cheap Chinese copies.

The device has unlimited range - walls or terrain do not affect the quality of reception. You may be halfway around the world and still hear what's going on in
the apartment, garage or at home.

Brand new, high quality.
Works with all standard GSM SIM cards and some 3G SIMs (EE 3G, Virgin 3G & Vodafone 3G) Device does not have a SIM lock.

Please remember to turn off the PIN password on the card. It's very simple to operate once installed: insert the SIM card into the bug and put the device in the room where the bugging is to be implemented.
To start listening you should phone the sim card located in the device.

This item ideally works in a surface mounted box a metal housing can interfere with the reception quality and cause noise interference.
If you have to mount in wall inside metal box we would recommend either Mains adapter or extension lead.

To use the features on this product you will require a compatible GSM sim card once you have tested ok put some credit on the sim to ensure that the network keeps it active.

It's always best to stick with a network that you know has a decent reception in the area that the product is being used, we normally recommend Vodafone, Virgin or EE in the UK as these have good network coverage. Device works with most GSM networks across the world.

O2 & the 3 Network sim cards will NOT work with listening devices as they are mainly 3g sim cards.

You can add a compatible GSM sim card to your purchase by selecting from here Sim Cards and Add to Cart.
