Although I haven't got a mobile phone myself, I think it's necessary for a
student to use a mobile phone. Students use their mobile phones mostly for
communicating with each other. In my opinion, its a must for students to mobile
phones. First, it's very helpful when you are in danger, you can call 110 for
help or ask others for help by phone. Second, when you are in a school where far
away from your home, but you miss your parents very much, you can use mobile
phone to call them. It's very convenient. In brief, it's necessary for a student
to use a mobile phone.
