You then call the device using a telephone from anywhere you like and it will automatically activate allowing you to hear all conversations up to 15 feet away from the device with crystal clarity.

This is the latest model with special high gain pre-amp for excellent sound quality. It can also accept any sim card in any country and the device is supplied with a standard UK sim card but you can change the supplied sim for a different one.

This device can be used in voice activated mode also. Simply send a text to the spy phone and it will call you when it hears any sound.

By a sending different text, it will revert back to normal mode operation where you call the device. It can be connected to the mains or pc to work indefinitely and charge an Iphone as well.

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 Virgin, EE or Vodafone in UK as these have good network coverage.

O2 & the 3 Network sim cards will NOT work with listening devices as they are mainly 3g sim cards, Virgin, EE & Vodafone normally work fine in most areas.

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