A total of 847 million Chinese people use mobile phones to surf the internet, an increase of 29.84 million from the end of last year.
Mobile phone users accounted for 99.1 per cent of the total netizens, up by 0.5 percentage points.
Faster internet service at lower costs has greatly boosted usage growth, with the average monthly mobile data usage per user reaching 7.2 gigabytes (GB), 1.2 times the global average, the report said, adding the internet availability rate in the country reached 61.2 per cent.
The average download speed of mobile broadband has increased by about six times in the last five years and the fee for mobile internet has dropped by over 90 per cent, state-run Xinhua news agency reported.
While China is the home for the largest number of internet users, it also has the most restrictions in place for use of web-based services.
Global social media outlets like Twitter, Facebook and Google-related services remain banned and the internet is controlled with massive firewalls to weed out the unauthorised content.
The country is preparing for the launch of 5G services which is seen critical because it can support the next generation of mobile devices in addition to new applications like driverless cars.
