Unicom, China's #2 mobile-phone service, has "started offering a 66-yuan-a-month ($10) plan for the iPhone after previously setting the lowest-priced package at 96 yuan," in competition with larger rival China Mobile Ltd., Bloomberg reports here.

"Unicom, the only carrier in China offering the iPhone with a service contract, added 1.82 million 3G subscribers for a total of 20.4 million in April, the company said this month.

"That lagged behind the 29.4 million 3G users for China Mobile, whose total customer base of 606.2 million is almost double Unicom’s 323.6 million. China Telecom, the country’s biggest fixed-line carrier, is in talks with Apple to offer a CDMA version of the iPhone...

"China Mobile said last week it cut call rates by an average of at least 15 percent for some customers."

How come mobile service is so much cheaper in China than here?
