GSM Double Wall Socket

This is a fully working UK style double wall socket that conceals a GSM unit capable of receiving covert calls to allow real time audio monitoring. This totally standard looking UK wall socket is perfect for both home and office applications as it will blend into its surroundings almost seamlessly.

Is the socket fully functional for powering other appliances?

Yes. Both outlets on the double wall socket function exactly like a standard UK mains plug. You can power lamps, computers, or any other household appliances while the listening device is active.

How sensitive is the internal microphone?

The high-gain microphone is designed to capture standard speech levels within a 6 metre radius. Even if the socket is installed behind a desk or near floor level, the digital sound processor ensures clear audio capture from across the room.

Does the device remain active if the socket switches are turned off?

Yes. The GSM module is hardwired directly to the internal mains supply. This means the listening unit remains powered and functional 24/7, regardless of whether the external socket switches are in the ‘on’ or ‘off’ position.

Will the device make any noise or show any lights when I call it?

None at all. The device is designed for total discretion. There are no ringing sounds, clicks, or flashing LED’s to indicate that a call is connected or that the microphone is active.

Can I use my own SIM card with this device?

Yes. While we provide a pre-installed EE SIM card to get you started, the unit is unlocked. You can easily swap it for a micro SIM from any network provider that offers the best signal strength in your specific area. /p>

Do I need to add credit to the SIM card?

To receive a call and listen in, the SIM card does not typically require credit. However, if you are using a Pay-as-you-go SIM, most networks require a small amount of activity (like a brief outgoing text or call every few months) to prevent the SIM from being deactivated.

Can anyone install this unit?

While the unit is designed to be a direct replacement for a standard UK double socket, we strongly recommend that installation is performed by a qualified electrician or a person competent in electrical DIY to ensure the mains wiring is handled safely.

Is there a limit to how far away I can be when I call the device?

No. Because the device operates on the global GSM mobile network, you can call it from any phone in the world. Whether you are in the next room or in another country, the connection remains the same.

What happens if there is a power cut?

Since the device is powered by the mains, it will shut down if the building loses power. However, as soon as the mains power is restored, the GSM unit will automatically reboot and reconnect to the network, ready for use again.

Will the device interfere with my Wi-Fi or other electronics?

No. The module is shielded and operates on standard cellular frequencies (4G/GSM), similar to a mobile phone. It will not cause interference with your home Wi-Fi or other electronic appliances.

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

• You will need a functioning mobile phone or landline to dial into the socket and listen to the audio feed.
• This unit is not battery-powered. It must be wired directly into a standard UK mains power circuit (200 ~ 240V) to function.
• Because this device involves live mains wiring, we strongly advise employing a qualified electrician for installation to ensure safety and compliance with electrical regulations.
• While an EE SIM is provided, you may replace it with any active Micro SIM that offers the best signal strength in your specific deployment area.
• The SIM does not require credit to receive calls, but Pay-as-you-go providers often deactivate SIM’s that show no outgoing activity (calls or texts) for extended periods (typically 3–6 months).
• We only supply this unit with a plastic faceplate. We cannot build these using brass or chrome metal fronts, as metal creates a ‘Faraday Cage’ effect that blocks GSM signals and renders the listening device inoperable.
• For the strongest possible cellular reception, we recommend using a plastic back box. If your current wall cavity uses a metal back box, you may experience reduced signal strength.
• Ensure the location where the socket will be installed has a stable cellular signal. Just like a mobile phone, the device requires a network connection to answer your calls.

• Call the number of the SIM from any phone (mobile or landline) to listen to live audio in the room where the socket is installed
• The internal GSM module is programmed to auto-answer incoming calls silently without any ringing or clicking
• Both plug sockets remain 100% functional, providing standard 240V AC power to appliances plugged into them
• The integrated microphone picks up standard conversation levels within a 6 metre radius
• Operates over the cellular network, meaning there is no distance limit – monitor the location from a different city or country
• Because the unit is hardwired into the mains circuit, it functions indefinitely without the need for recharging or battery replacements
• While supplied with an EE SIM, the GSM module is unlocked to accept any micro SIM from any provider, allowing you to choose the strongest local signal
