We had exclusively reported about Microsoft planning to bring Lumia 640 DS LTE in India, but we didn’t hear anything about this since then. But seems Microsoft may be planning to do so after all. Recently Lumia 640 DS LTE variant RM-1075 has been imported in India buts Microsoft has yet to made an announcement officially with regards to availability.
In Fact the Product page for Lumia 640 DS LTE has been up for a while now with coming soon status. Lumia 640 DS version RM-1077 has also been out of stock for quite sometime in India and you can still not get one from official stores and even online it is available from one retailer only.
Thanks Sudipt for the tip. Cheers!!
