An unlocked Desire 816 is offered for $405 (1,299 RON) in Romania. The version that's available has dual SIM support - which might not be the case with the variants sold in other markets.
Announced at MWC 2014 in late February, the HTC Desire 816 is a large mid-end smartphone that measures 6.17 x 3.10 x 0.31 inches (156.6 x 78.7 x 7.99 mm) and runs Android 4.4 KitKat. That aside, it offers a 5.5-inch 720p display, quad-core 1.6GHz Snapdragon 400 processor, 13MP rear camera, 5MP front-facing camera, 1.5GB of RAM, and 8GB of expandable internal memory. The handset comes with a 2600 mAh battery.
It’s said that the Desire 816 will also be released in the UK and the US, most probably starting May. AT&T might carry the new Desire in the US, but that hasn’t been confirmed yet.
