Do you think that mobile phones should be switched off during the lesson?

Nowadays a lot of people are using mobile phones as a means of communication. it results that not only older people are using them, the younger generation also uses them. We can see that now primary school students have mobile phones. In my opinion, mobile phones should not be switched off during lessons. Firstly, mobile phones should not be switched off because you never know when parents can call you to say something important or inform you about something. Also, someone else can call you and say that something horrible has happened to your parents. You will never know what they have to say to you until you pick up a phone. Secondly, I think that students have to switch off the sound of their mobile phones or turn on only the vibration. As a result, they will less disturb their classmates and teachers during the class. On the other hand, if students do not switch off their mobile phones, it will distract from work not only themselves, but their classmates too. As a result everyone will have lack of concentration. To sum up, I can say that students themselves have to be responsible for their mobile phones and not to think only about themselves but also about people who are around them.
