A mobile phone jammer is a device that is used to stop text
as well as verbal communication process within mobile phones. It is basically
used to block all available cellular frequency bands in the network. Mobile
Phone Jammers were mainly designed to disrupt and stop communications between
rebels and terrorist groups to stop their illegal and violent operations. When
you use a mobile phone jammer, a low power radio signal is broadcast and this
signal is capable of cutting off communication between the mobile phones and
its cellular base stations. As a result, all the cell phones of the affected
area will show “No Service” and incoming calls are blocked. Once when the
mobile jammer is turned off, all the mobile phones will automatically
reestablish communication with the cellular base stations and those cell phones
affected by the jammer will once again be able to receive cellular services.
