While we know that BLU was planning an official launch of sorts in India, the devices have made its way on Snapdeal.com already. Headquartered in Miami, Florida, BLU has sold over 25 million unlocked mobile devices in over 40 countries. Both 4G Windows Phone 8.1 devices are targeted at the budget market, and will receive the Windows 10 Mobile upgrade when it arrives. While both phones are powered by similar internals, the major difference is in the display and camera departments. Both Win HD LTE and Win Jr LTE are dual SIM devices.
