mobile phone jammer

A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between  the cell-phone base station and the mobile phone, effectively disabling mobile phones within the range of the jammer, preventing them  from transmitting signals and from receiving signals . Mobile phone jammer can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues.

Blocking single callers can be an annoying time waster. Mobile Phone Jammer remove that annoyance by blocking all incoming calls at once.
