This report also said that the number of Chinese SMS users are 765 million people in 2012. The number of Chinese mobile user was about 1100 million people in the end of 2012, hence it follows that about 70% of mobile users use SMS in China.
Actually SMS is the most popular method of communication by mobile phone in China, and many people use it to send the greeting at holiday or memorial day, such as Chinese new year.
But going back to the subject, the number of SMS messages was increasing only 2.1% compared to 2011. And the number of mobile phone users in China was increasing about 11% compared to the previous year, so it can be said that the number of SMS messages was substantially negative growth in 2012.
One of this reason was the rapid progress of WeChat or Weibo. Mainly young people shifted the communication method on mobile phone from SMS to WeChat or Weibo. WeChat and Weibo already each have over 300 million users, and this growth will continue in 2013. So the number of SMS messages may be truly negative growth in 2013.
