What is a phone jammer?

A phone jammer transmits low power radio signals to cut off communications between cell phones and cell base stations. It does not interfere with any communications other than cellular phones within the defined regulated zone.
Upon activating a phone jammer, all idle phones will indicate ‘NO NETWORK’. Incoming calls are blocked as if the cellular hand phone were off. When the phone jammer is turned off, all cell hand phones will automatically re-establish communications and provide full service.

A phone jammer actively sends broadcast radio signals. Depending on the country you live in, the possession and/or use of a phone jammer might be illegal.
