text: In the environment of an emergency, I believe that if students have their cell phones, that they can call their parents. Not during school hours regularly, but in the case of an emergency. If they did not have their phones with them and their was an emergency, then their parents might not be able to contact them and they will be worried. Also, if they were sick, and the school didn't have any phones, they could call and tell their parents to pick them up from school.
