    Hello, Marlon
    There are many ways to jam cell phone signals. The most traditional way is to create a Faraday cage. If you work in a library, try this approach.
    Another method is the recently popular cell phone signal jammer. This kind of device has the advantages of low price, small size and quick effect.

Howdy, Stranger!
