China’s three mobile operators added another 26.5 million 4G customers in October, taking the country’s 4G user base to more than 700 million.

China Mobile continued to widen its lead on rivals, adding 16 million 4G subscribers last month, while China Telecom added 5.5 million and China Unicom picked up 5.1 million.

China Mobile announced last week its 4G subscriber base surpassed the 500 million mark in early November. China Telecom has 113 million 4G users and China Unicom has 94 million.

The three operators have collectively added more than 288 million 4G subscribers in 2016.

At the end of October, China Mobile had 846 million total mobile subscribers (a net gain of 19.5 million this year), China Unicom had 262.6 million subs (10.3 million net additions) and China Telecom had 214 million (up by 16 million).

At Huawei’s Mobile Broadband Forum in Tokyo last week, Li Yue, China Mobile president and CEO, said it has built out 1.4 million 4G base stations in just three years, which represents a third of the global total. It also deployed the largest VoLTE network in the world, reaching 313 cities in the country.
