The 920T will be the first Windows Phone operating on China Mobile’s 3G service, and has anticipated for some time, especially after the carrier accidentally broke the news with a post on Sina Weibo (China's Twitter-like service) last month.
Stephen Elop, President and CEO of Nokia said,
We are delighted to partner with China Mobile, the world’s largest operator, to introduce China’s first Lumia based on Windows Phone 8. People around the world are responding positively to the new Lumia devices, and we’re confident that the enthusiasm will extend to China with the Lumia 920T.However, Nokia isn't expected to make much of a dent with the new phone. A recent report said Android had a 90 percent market share, and the iPhone is carried by No. 2 and No. 3 carriers China Unicom and China Telecom.
The Lumia 920 itself was unveiled in September, but the T addendum exists because this device supports TD-SCDMA, China Mobile’s unique 3G service, as well as its burgeoning TD-LTE protocol.
These unique technologies are believed to be the main reason why Apple hasn't partnered with the operator, which is easily the largest carrier in China, and the largest single carrier in the world, with 703 million subscribers.
