This amazing GSM listening bug unit delivers simply fantastic audio quality, strong deployment magnets in a nice such compact enclosure. 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 because that SIM is not actually making them any money. When the number of the inserted SIM is contacted, the device will, without alerting attention in any way, auto-answer the call and open up its in-built sensitive microphone which will enable the caller to listen into the surroundings up to 10 metres away from where the GSM bug has been placed. Superb Microphone – Discreet Auto-answering with this Listening DeviceĪs with all GSM Bugs, the GSM Enduro Live Listening Bug requires a mobile phone SIM card inserted within so that it can be called from anywhere in the world, if required. The GSM Enduro Live Listening Device is a longterm audio bug, with deployment magnets, that can provide the ability to listen ‘live’ to what is happening in the environment where it has been placed without the need to have a permanent mains power supply.
