What can block cell phone signal

  • SallyWolf
    I'm a restaurant manager. I want to know how to block cell phone signal. Telephone rings and loud conversations are often heard during meals. So I want to make the customers have a more comfortable dining environment

    Hello, Sally
    Usually in this case, you can write a notice forbidding the use of mobile phones in restaurants.
    Of course, this approach may not work. That's when you need your cell phone signal jammer. Once these devices are turned on, they can quickly block out the signal from nearby phones. Provide a good dining environment for your restaurant.

Howdy, Stranger!
