200 million dual-SIM phones?

I wrote a post about the new crop of dual-SIM handsets a couple of months ago, and since then it's been a slow undercurrent, with a few new ones at Barcelona, but otherwise it's been a fairly quiet trend.

Or so I thought.

According to this article, over 200 million were produced in China last year!

Given the whole of the handset market is only 1.1 billion, and a big chunk is taken up by "normal" Nokia, Samsung etc phones, that figure sounds implausibly enormous to me - but if anyone from China or elsewhere could comment, I'd be fascinated to be proved wrong.
