This paper is the latest report of research on high school students and mobile phone use. Mobile phones are extremely popular with high school students who seem to be able to master them more easily than adults. The mobile phone brought big influence to the structure of high school students' life time and how to make relationships with their friends. However, investigating high school students' mobile phone use indicates that students have little or no awareness of the fees and costs related to owning a mobile phone. At the same time, consumer education about mobile phones is not provided by schools. In response to this, the author presents teaching materials which can be used to educate students about the consumer awareness of mobile phone fees and costs, and proposes that such education should become part of the consumer education curriculum.
