The question can be raised by yourself one day, how jamming devices work on mobile phones? We find in most places such as mosques, hospitals and during the passage of a presidential or royal procession, all the phones stop working.

The answer is very simple! But before you answer, let me first explain how your cell phone works.

When running a cell phone, it just makes the analysis of all mobile towers near where the links are connected to the nearest tower and when you move away the area covered by the tower, phone automatically searches for the nearest new tower and so on.
And of course, the phone has an almost frequency between 900 MHz and 1800 MHz, a frequency that allows the passage of data (voice calls). Thus, the devices confused when they work, they publish frequency signals between 900 and 1800 MHz, which force the phone to connect to these devices instead of the tower.
 
 
Of course, there are many types of these devices that interfere with the phones for short distances and are often used in mosques and hospitals, but there are others, not for ordinary citizens, they are often used in the security and in the military field. In addition, some of them may not only interfere with voice calls, but also with video and internet.
