Is a cell phone jammer installed at the gas station?

  • Recently, I discovered that every time I drive to a gas station, I find that my mobile phone has no signal, and I cannot use my mobile phone to make payments. I need to pay for gas now.

    The crossover of mobile phone signals will produce sparks, which may lead to serious events such as explosions. Therefore, gas stations have installed mobile cell phone jammer to prevent calls. This is a necessary tool to provide a safe environment. It usually also appears in school classrooms to prevent students from using mobile phones in class, and on the other hand to prevent them from cheating in exams. But I think this is for safety reasons, because we often see warnings that gas stations do not make any calls. This may give you an idea of why you need to install jammers at gas stations.

Howdy, Stranger!
