GSM Phone Charger Listening Plug

This dual-purpose device functions as a standard USB mains charger while housing a sophisticated 4G GSM module for covert, real-time audio surveillance. Designed to be completely indistinguishable from a regular power adapter, it provides an ideal monitoring solution for both residential and professional environments.

Mains Powered Listening Bug – Totally Discreet in Use

Unlike battery-operated bugs that eventually fail, this GSM Phone Charge Listening Plug is mains-powered. Simply plug it into any live wall outlet for permanent, 24/7 operational readiness. Because it draws power directly from the socket, you can dial in from any phone in the world, at any time, without ever worrying about the device dying because of battery limitation.

Complete Stealth & Automation

Security and discretion are at the core of this device’s design:

• Auto-Answer Mode: The unit silently accepts incoming calls without any ringtones, clicks, or flashing lights.
• Undetectable Operation: There are no external indicators to suggest the device is anything other than a standard charger, even while a call is active.
• Global Access: It functions exactly like a mobile phone, allowing you to listen in from across the street or across the globe.

Fully Functional GSM Listening Bug – Charge Any USB Device

To ensure the device remains “above suspicion,” the USB port is fully operational. You can use it to charge smartphones, tablets, or any USB-powered electronics. Whether it is used as a standalone plug or with a charging cable attached, it blends seamlessly into its surroundings.

Superb Clarity Microphone – Wide Listening Radius

Equipped with a sensitive microphone and a digital sound processor, the unit captures audio within a 6-metre radius. The advanced pickup ensures that even if the charger is tucked away behind furniture or plugged in near floor level, normal speech and ambient sounds remain audible whilst listening in over the telephone.

Three Plug Styles Available

There are 3 variations available for this product; A white 3-Pin UK style plug with single USB port outlet; a black 3-Pin UK style plug with single USB port outlet; a black European 2-Pin style plug with a single USB outlet. The type/colour is selectable from the package options menu. Also see images to view excatly the style, etc. you should expect.

Will the GSM listening bug work as a standard USB mains adapter plug?

Yes, it will power devices plugged into it (using USB lead) whilst working as a listening device.

How sensitive is the microphone?

The microphone should easily pick up sounds in a radius of up to 8 metres in quiet environment conditions.

Does the listening bug call me if it hears sound where it is plugged in?

Yes, there is functionality built into the operating system to facilitate this, however this will require the SIM card to have calling credit.

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 the listening device 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.

Can This be actually used to charge a mobile phone?

Yes, in fact it can be used to power or charge up many standard USB/USB2 devices.

Consider the Following When Using this Listening Bug:

• You will need a working phone (mobile or landline) to enable you to listen in to the bug.
• If the supplied EE SIM card is not ideal for your location, then this will need to be replaced with an active SIM card of your choice to suit the location or your own needs as to network suitability.
• If changing the SIM card then you will require a Watch back opening tool to open up the plug to access the SIM card inside – one is normally supplied.
• This GSM listening bug is NOT battery powered and must be plugged into a mains power outlet that is switched on.
• To be able to take advantage of the voice activation facility on this version of the device (if you choose this version) the SIM card inside the Double Adapter will require credit or will need to be a contract SIM. The SIM card supplied in this covert listening device does NOT have credit on it and as such it is not possible to use the voice activation facility unless you put credit on this SIM.
