Legality of cellphone jammers

In the last two years the Radiocommunications Agency has become aware of devices, being marketed around the world, that can block mobile phone calls. These devices transmit radio signals that prevent communications between cellular handsets and cellular base stations.

It is illegal to install or use these devices in the UK. Use of these devices constitutes an offence contrary to sections 1 (unlicensed use) and 13 (deliberate interference) of the Wireless Telegraphy 1949 Act. Any outlets marketing such devices in the UK may be prosecuted for inciting the public to commit offences.

The cellular operators are licensed to provide a mobile telephone service throughout the UK. Cellular phones are used for a variety of business and public applications, and cellular customers expect to be able to make and receive telephone calls within the coverage areas provided by the operators. The Agency will take all necessary steps to ensure that cellphone jammers are not used in the UK.
