fundamental function of cell phones is to communicate your message frequently.everyone has cell phone without any discrimination of age group.it is my notion that students should be allowed for cell phones at high school because if their parents would be stuck in traffic or late due to unforeseen circumstances then they could contact with their parents via cell phone.beside all above reasons cell phone could be used for research works and to find way or routes as well as weather forecasting.so all in all students should be allowed cell phones at high schools but it should be conditional.
