The country introduced virtual operator. According to relevant public information, the Ministry of Industry and Information Technology has introduced virtual operator, and virtual operator is the same communication company as China Mobile, China Unicom and China Telecom. By distributing parcels, it can settle its own expenses. Therefore, the overall communication market tends to be stable, and so many virtual operator companies join in, which leads to the decline of Unicom's market share. China United Network Communications Group Co., Ltd. was established on June 6, 2009 on the basis of the former China Netcom and the former China Unicom.
