Cell phone jammers in schools are becoming more popular, and for good reason. Many teachers are fed up with trying to stop students from texting in class, and want to know how to stop cell phone use in the classroom. Students ignore lectures while they surf social networks. Some send texts, and even do research online, in order to cheat on exams.
