It's quite common that students use mobile phones in many middle schools. Though some schools don't allow students to use them at school, many students still think they have the right to have mobile phones. They think it's easier for them to communicate with each other.
I don't think it is necessary for students to use mobile phones to keep in touch with each other. We all know mobile phones give unpleasant noise when we are having a lesson.Besides, using mobile phones costs a lot of money. We are students and our main task is to study. So we should put away our mobile phones and focus on our study.

One possible version：
Dear Jim，
Now, I'm writing a letter to you on Mars. It's really wonderful to live on Mars.
I think life on Mars is more comfortable and more interesting than that on the Earth. We have online schools instead of real ones. We have lessons, do our homework, take exams and talk with teachers and classmates through the computer connected to the interplanetary network at home. It is not so crowded here so we have more space. Most of our housework is done by robots so that we can have more time for our hobbies. Mars is very beautiful. There are green trees and beautiful flowers everywhere, and there is no pollution here. We have supermarkets in our neighbourhood. They make our life more convenient.
Yours，
Eric
