NEW YORK (TheStreet) -- China, the world's largest mobile phone market, recently crossed the one billion mobile connections mark in March. To put this number in perspective, the U.S. currently has just over 330 million active connections in all.While the Chinese figure may not be reflective of the actual number of mobile users in country, as some of these connections are currently inactive, it is still a compelling statistic that shows the huge growth opportunity that China presents for many smartphone manufacturers. At the same time, it is also a huge opportunity for the incumbent Chinese telecom providers such as China Mobile ( CHL, China Unicom ( CHU - Get Report) and China Telecom ( CHA - Get Report)to tap their huge 2G subscriber base and drive the demand for the more lucrative 3G data services. Of the three Chinese carriers, China Telecom may be the smallest but its subscriber base of over 135 million (135.83 million as of March) easily puts most wireless carriers in the developed world to shame. The largest wireless carrier in the U.S., Verizon, has about 110 million total connections currently and it operates in an increasingly saturated market.
China Telecom has also been helped by the fact that China Mobile currently runs its 3G network on a homegrown proprietary TD-SCDMA standard that is not compatible with many smartphones. That may soon end, however, as Qualcomm recently launched a wireless chipset that supports the standard, making it likely that many popular smartphones, including the iPhone 4S, could be making their way to the carrier before the year end. However such a deal has not been officially announced yet and China Telecom will be looking to make the most of its iPhone opportunity before that happens.
