WeChat calls beat telecom companies

WeChat has eclipsed telecom carriers to become the new darling for Chinese people to make calls, a study has found.

The 768 million active WeChat users - more than double the entire population of the United States - made over 100 million voice and video calls everyday via the app in 2016, its developer Tencent Group Holdings Ltd said in a report on Wednesday.
