As can be seen from the chart, great changes have been taking place in the ownership of mobile phones in china. At the end of 2002, there were 25 million mobile users, but two years later, the number has reached up to 35 million.
People have found mobile phones very convenient. They can get in touch with each other whenever they like and wherever they are. There are many different functions for different needs, such as sending short messages and surfing the Internet. However, it may also bring us more trouble. For example, you will have to pay for a wrong dialing, and the radiation from the phone may do harm to our health. In spite of this, the number of people having mobile phones is still increasing greatly.
