The mobile phone is one of the latest editions of modern communication technology. It is handy and portable as the term ‘mobile’ signifies. It is a small telephone that can be carried in a hand or pocket. The effective speaking range of man is only a few yards. But with the help of a mobile phone, he has increased the range to hundreds of miles. Is it not a miracle that a man walking along a street or riding on a vehicle can speak to his friends or relatives hundreds of miles away? Is it not useful for a man while shopping in the market to pass or valuable information to people at home or at the distant place? A man traveling a distant part of the land is talking to his friends or relatives at home. And all these are done at a nominal cost! A mobile phone is very useful for important persons such as politicians, artists, doctors, businessmen, and high officials. But like all other gifts of science, it is not an unmixed blessing. The mobile phone is a useful instrument and it can be used by both good and bad people. The police can use it in committing crimes. The mobile phone is, however, an indispensable annexation to the modern lifestyle.
