An increasing number of middle school students in China are using mobile phones. People are debating whether students should have mobile phones. Mobile phone supporters suggest that they should not be forbidden. Mobile phones are very convenient for parents and children to keep in touch with one another.

　　However, some people feel that students can chat with their parents or friends by using public phones instead of mobile phones. This is a cheaper and safer way of communicating as students will have no chance to send dirty jokes or other unhealthy news.
