text: They also allow kids to contact their parents if needed. Me and my friends take a trolley home sometimes, but i don't always get to take it because someone is already at school to pick me up. If i could use my phone at a break though I would be able to call my mom and ask her if i could take the trolley before she would have left. Or, what if a kid accidentally left a project or paper at home and it was due the next period. All he would have to do is call his mom or someone at home to come to the school and drop it off. As you can see, cell phones allow kids to contact their parents in times of need.
