📡 Introduction to Mobile Phone Signal Jammers
A mobile phone signal jammer (also known as a cell phone signal blocker or signal disruptor) is an electronic device designed to interfere with and block mobile communication signals within a certain area. This prevents mobile phones from making or receiving calls, sending messages, or connecting to mobile data networks.

🔧 How It Works
Mobile phones communicate with nearby cell towers via radio frequency (RF) signals such as GSM, CDMA, 3G, 4G, and 5G. A signal jammer emits radio noise or interference on the same frequencies, effectively disrupting the communication between the phone and the network tower by overpowering the legitimate signals.

🏫 Common Usage Scenarios
Examination halls (to prevent cheating)
Government/military facilities (to prevent information leakage)
Prisons (to block unauthorized inmate communication)
Hospitals (to avoid interference with equipment)
Theaters, libraries, and churches (to maintain silence and focus)
