He noted that products related to the 5G network, including systems, chips and terminals, are almost ready for commercial use, and the technology will be extensively（广泛地）used in key areas such as industrial Internet and connected car technology that ties computers on the vehicles to WiFi.‎ Chen Zhaoxiong, vice-minister of industry and technology, said that the development of the 5G network could give rise to massive opportunities in industrial growth and job creation.The ministry will make continuous efforts to promote the use of 1000Mb broadband connections and expand the coverage of fiber-optical broadband services, he said. Meanwhile, the ministry will upgrade telecom networks and operation systems by the end of November to ensure that mobile phone users nationwide can switch service carriers without changing phone numbers, he said.

Carriers are also required to make public all their service packages and make them all available for the users, he added. “We will step up investigations on wrongdoings so that consumers can see their telecom bill plain and clear,” he said.‎ China has expanded the download speed of mobile broadband sixfold compared with five years ago, while the charges for broadband connections and mobile Internet were down by 90 percent, according to the Ministry of Industry and Information Technology.‎ China’s digital economy reached a total volume of 31 trillion yuan ($4.5 trillion), or 34.8 percent of its GDP, in 2018, according to the ministry.‎ ‎1.
