学生可以带手机到学校吗？为什么？

Absolutely you can. It's sth about your personal rights.I believe you can't find any rule on your student regulations that you can't own a mobile phone. Perhaps your teachers will oppose because they are worried about the virulent consumptive competition among students.

if you are middle school student, i think it is not suitable to take phone to school.if you are college student you can have your phone .
when yor are having lesson i suggest you'd better turn off your phone.it is a polite way for you.

可以哦 因为国家也没有规定学生不让用手机哦
