Usually, the cost of reading a novel on a mobile phone depended on the price of the mobile reading software or platform. Different platforms and software might have different charging standards. Generally speaking, the charging standard would be calculated according to the length of the chapter and the number of words. For example, in some free novel reading applications, each chapter may be free to read, but you may need to pay to view more complete chapters. In paid applications, you may pay for each chapter or you may need to pay according to the total number of words in the chapter. In addition, some novels might offer a monthly or weekly fee for a certain amount of time. This way, one could always read the relevant content of the novel without worrying about the cost. In short, the specific fee would depend on the genre of the novel, the platform and software, as well as the number of chapters and words read.
