The first important advantage of mobile phones is that they save valuable time and space. When we have to tell emergency information, we can tell quickly and easily through the mobile phones specially in distant space. A additional advantage of using mobile phones is that they are useful for us. Nowadays more and more people are becoming users of smart phones. We download many kind of educated application such as lingual dictionaries, test practice, book reader...etc in order to use our lessons and homework.
The main disadvantage of mobile phones is that they are one reason of isolation. Instead of real communication , we only press the buttons. Another point against them is that they might be harmful to our health. Because of many electrical waves, they influence our brain and body.
All in all, I believe that mobile phones are useful, helpful tool in our lives, but only when used sensibly. We should remind that mobile phones never replace a human being or real communication.
