Mobile phones may be cool but they can also be extremely dangerous.
The first reason why is because people can bully each other.
The second reason is that they text and talk to each other without even focusing on what they suppose to be doing.
Another reason is that because they are just wasting their money or their parent;s money on a phone when they could be buying something thats needed.
I think children shouldn’t own a mobile phone until they're older enough to manage own self.
