As much as the 32 to 64 gigabytes of internal storage in the standard HTC One might be enough for most users in the West, different markets sometimes call for different features. And a feature difference is exactly what we're seeing in the first leaked shots of what seems to be a Chinese HTC One variant going by the model name 802w. That's right -- there's dual SIM support, in addition to a microSD slot.
Spotted by Engadget Chinese over on Sina Weibo, the 802w hides all extra stuff behind a removable back cover. That's something not found on the European and American HTC One models, which pack everything into a sealed unibody enclosure with only a pop-out microSIM tray along the left edge. The Chinese handset, said to be headed to China Unicom, has one SIM slot for WCDMA/GSM (data and voice) and another for GSM (voice only), a trait common to many dual-SIM devices.
Even if it's a legit HTC-made product and not a knock-off, we wouldn't hold our breath for HTC One variants like this outside of the Far East. What's more, the prospect of using such a device without Google services might not make the 802w a particularly attractive prospect for import. But at least we'll always be able to fawn over the picture above.
