On the one hand, I strongly agree with the idea that the use of mobile phones is harmful in some ways. There are many people who use this device with immoral purposes that harm other individuals. Specifically, they can use social networks to steal money on banking applications or spread inaccurate information to trick everyone into doing bad things. As a result, smartphones must be used under the control of the government.

   On the other hand, I believe that mobile phones should not be prohibited like smoking. From my perspective, smartphones bring to people' lives numerous benefits that smoking does not have, including contact with other individuals, entertainment with a huge category of video games, film and so forth. Moreover, mobile phones also play a virtual role in the career of somebody because this device can assist many people to earn money. Consequently, we need to use mobile phones in the proper way rather than disallow using them. 

   On the whole, mobiles phones can influence human lives in some unhelpful ways but we need not have forbidden the use of them due to its huge advantages to society.
