Can teachers use cell phone jammers?

I'm a techer. Although I know that using mobile phones can help students learn more knowledge. But I still can't stand it when students use mobile phones to chat or surf social software in class. I've heard that there's a device called a cell phone signal jammer that can jam cell phone signals. Can I buy and use it?

Hi, Nora.
Cell phone signal jammer can block cell phone signal effectively indeed. When such devices are turned on, they can effectively block cell phone signals around them.
Whether you can buy and use it depends on the policies of your country. Most southeast Asian countries and parts of Europe now allow education institutions to use such equipment. North America is also trying to introduce such equipment.
