Spy Review

This bug is small and discreet, but allows you to listen in to any conversation within a five metre radius of wherever it is placed. It is the size of a small matchbox and works as a transmitter. You merely have to insert a sim card into it to become operational.

As the transmitter works with sims on all three bands, it can be used in almost all places in the world. Its activation is extremely simple, you just place the sim in the bug and it is ready to use.

When you call from any landline or mobile phone, your call gets connected and you can listen in to all conversations around the bug on your mobile phone.

You can even put this bug in a car if you want to monitor conversations when people are on the move (though the sim should be able to receive the signal for it to work).

There may be better ways to listen into conversations as there are more discreet ways to do so, but this little device has one advantage – its size and versatility and the use of use. What’s more, its not covered with a fancy exterior, it could easily look like a device used for any purpose and not necessarily a bug.

Of course, given that its not a listening device specifically designed for a fixed location, it cannot run on electrical power so there is going to be a limit to how long it can be used for in a single session. For this reason, the recommendation is to use very long lasting batteries if its expected the listening in could be done over a period of several days at least.

The major disadvantage is the size of area it covers with only a 5 metre radius so it needs to be very precise where the device is located.
