text: Students may also need their cell phones for after school rides. Like if their parents won't pick them up and they need to tell them, or a different relative is going to take them home. If the students were not allowed to bring cell phones at all, what would happen if one of them was the last one to go home and somebody held a gun to their face and told them to get in their car? These students would need to call 911, but if they don't have their cell phones, they would be in some big trouble.
