2010165438+122 October, the Ministry of Industry and Information Technology will carry out the pilot work of mobile phone number portability in Tianjin and Hainan. Users can apply for mobile phone number portability from Telecom or China Unicom for free without changing their original numbers. According to the reporter's understanding, the pilot period of inter-network number portability is 6 months, which provides useful experience for the next stage of national implementation of number portability business. As two pilot projects in China, Tianjin and Hainan adopted different models. Tianjin adopts two-way network transfer, that is, mobile 2G users and users between China Telecom and China Unicom can transfer to each other. However, Hainan implements one-way network transfer, and only mobile 2G users can transfer their numbers to telecom or Unicom.

Although the high-end group of China Unicom's 6,543.8+0.52 billion GSM users may switch to China Mobile for higher call quality and lower cost, China Unicom will benefit the most from the port number transfer because the company's profit in 2065,438+0 is highly sensitive to the monthly net growth of 3G users.

As the network provided by China Telecom is the best in the industry, the company will also benefit from users with high ARPU (average income per user), but the cost of mobile phone replacement (from GSM to CDMA) may offset some benefits.

China Mobile seems to be the only company adversely affected, because the cost of maintaining users will rise, and some high-end users will give up the current 2G network in order to seek better data and voice service quality, resulting in the loss of customers.
