 Mobile phones were for business people twenty years ago, a lot of people prefer to talk face to face, but nowadays all people have one and prefer to talk on their mobiles.

Teenagers use it for a lot of things, they communicate with their family and friends at any time, play video games, study with some apps, send text messages quickly and more. But it is so bad too, because they are in their mobile phones all time and don't talk with people face to face, moreover there are social networks where teenagers spend a lot of time watching  what their friends upload. Moreover there are bad people use it to hurt other people with comments.

To conclude, I think mobile phones are definitely essential for teenagers, but they have to use them less time and go out to talk with real people.
