China Mobile, the largest mobile carrier in the world, still does not have an agreement with Apple to sell the company’s iPhone its 655 million customers. Despite that, the company has announced that it has surpassed 15 million iPhone users on China Mobile’s network, Sina Tech reported on Monday. The carrier has added more than five million users since October, a rate of more than 35,000 users per day. Those customers can use text, voice and only 2G data, however China Mobile has built out a nationwide Wi-Fi network to make up for its 3G shortcomings. Apple’s exclusive deal with China Unicom is coming to an end as the nation’s third largest operator, China Telecom, will begin selling the iPhone 4S on Friday. Analysts at Morgan Stanley predicted earlier this year that if a deal with China Mobile were reached, the carrier could sell an additional 60 million devices by the end of 2013.
