Everyone hates cell phones-movies, classrooms, funerals at inappropriate times (especially for those with happy disco ringtones), and of course religious services. Kenyan Muslims are happy to find devices that interfere with mobile phones: Kenya's Imam has long complained that mobile phones keep ringing.There is also an emergency conference, and you do n’t want to attend any unwanted calls or messages during important meetings, you can use cell phone blocking technology. The technology enables people to avoid calls and text messages without turning off their phones. Enabling the technology will directly block the signal from the base station, making it impossible for people to communicate with others through mobile phones.
