I think cell phones should be allowed in school because if you forget something at home you could call your parents to bring it to school. Like when you forget your homework. Also when your staying at school and you forget to tell your parents that your staying at school, and or you want to go somewhere after school to hang out with your friends. As in the case of an emergency, a cell phone can be very useful to contact family members or the authorities. In the schools case, it would help in studying and researching alone. There is even an program in which students can bring their phone or tablet to school to use for educational purposes, And most importantly, I think students need to take care of the phone and should be used in proper time
