text: Students now a days think its cool to be carrying a cell phone so of course they're gonna be showing it to there friends or giving each other numbers. Usually they be showing and using them in class when teachers are giving directions and cause of the rules it sometimes gets more tempted to use your self phone. So if you change the rules there's a probability that students mite be using there cell phones at time when teachers aren't giving directions or at times when they have to finish there work before they do anything else.
