The first advantage is that people can get in touch with friends whenever they want. Secondly, you won't need to go back home or go use a public telephone to call people. Thirdly, it is very small and light so we can take it anywhere.
On the other hand, there are also disadvantages. For example, people won't talk together so much and use email. Also, we are not allowed to use them on the train or in places where there are lots of people. Additionally, mobile phones need to get charged and batteries don't last long.
In conclusion, there are some advantages and disadvantages, so I think that we should not use them too much if it is not necessary, and talk together face to face instead. I think mobile phones are a great invention, but I haven't got one yet.
