A survey report released on Thursday said 70.9 percent of primary and middle school students in China use the WeChat instant messaging App.
At the same time, 75.9 percent of Chinese children have their own mobile phones, according to the China National Children's Center.
The figures were based on a survey of nearly 9,000 children across China.
However, 28.8 percent of them never read news online and 43.2 percent have never touched newspaper.
The center called for efforts to address the digital divide between urban and rural education and protect children's privacy as Internet users.
