BEIJING—With 5 million inhabitants using mobile phones, Shanghai has more users than any other city in China. Around 4 million are customers of Shanghai Mobile; the others are connected to Shanghai Unicom’s network.
Shanghai Mobile has invested US$750 million to expand network capacity to 9 million by the end of the year, 5 million of which are supplied by an Alcatel joint venture. The annual growth rate of mobile-phone users in Shanghai is 85 percent, but many of the newcomers are low-income customers, such as students.<
