Do gas stations need to install cell phone jammers?
-
Recently, I found that every time I drove to a gas station, I found that the mobile phone had no signal and could not be used normally. It turned out that the gas station installed a mobile phone jammer. Why is this happening?

Gas stations need radio waves to make calls, which may cause serious incidents such as explosions, so gas stations have installed cell phone portable jammer to prevent calls. This is a necessary tool to provide a safe environment.
