If someone had said 50 years ago that people would be walking around with small wireless telephones in their hands, we would have called him or her crazy. But now, almost everyone has at least one of them. People everywhere are walking around talking on their mobile phones. The phones are even being used for more than just communication. People use them to play games, watch television, listen to music, pay money online, and find information. They have beome a very important part of our lives. Mobile phones have not only made our lives more convenient, but they have changed the way we live. Before we had mobile phones, it was hard to reach a friend that was away from home. But thanks to these small devices, people can now get in touch with anyone, at any place, and at any time.
