How to jam mobile phone signals in school

    With more and more applications of mobile phones, more and more people pay attention to mobile phones. As a result, many students are still paying attention to their mobile phones in classroom. Our school has been looking for an effective way to prevent students from being distracted. Can you give me some advice?

    Hello, Trista
    In response to this situation, there is currently an effective solution in Asian countries. They will install cell phone signal jammer around the school. Turn on these devices during class and block all cell phone signals

Howdy, Stranger!
