Mobile phones have become an indispensable part of our daily lives. Discuss

example, when we are outdoors, where there are no telephones, we can use our handy mobile phone. Secondly, mobile phones enable us to call for help during times of emergency. For instance, if you are involved in an accident or if you witness a crime taking place, you can call the police immediately using your mobile phone. There have been some cases in which the police made use of the victims' cell phones' networks to locate the kidnappers. Some people feel uncomfortable or handicapped without their mobiles as they have become a necessity in our daily lives. This is mainly due to the convenience of mobiles and their varied functions such as MP3 players, radios and games. Mobiles are not only a great time-saving device, but they are a source of entertainment too.On the other hand, there are disadvantages of using mobile phones, too. Although mobile phones are convenient, they can belost easily since they are quite small. Talking on mobile phones can also be expensive because we need to pay high roaming costs when we are overseas. In addition, mobiles are believed by some people to give out radioactive waves and some scientists believe that this radioactivity can cause brain tumors or damage our ears. There is still no solid evidence to prove that mobile phones are safe to use. Another problem is that people can easily become addicted to mobile phones since they are now multi-purposed with different functions. The convenience of mobile phones can also cause a lot of problems such as cheating in tests as it is now easy for students to access the Internet at any time. People start to abuse mobile phones. This may affect the students at school as they may play games and send messages during lessons. Also, there are some places where there is no signal for the mobile phones so you can only make emergency calls, which is sometimes very inconvenient.In conclusion, I think that mobile phones are indispensable tools that we cannot live without, but we should avoid abusing them. Therefore, we should think carefully about the advantages and drawbacks before purchasing a mobile phone, and ask ourselves why we need a mobile phone and whether we will be able to use it responsibly.
