Update, February 20, 2016:

Intex Aqua Fish will be introduced only by Jolla at MWC16. I've confirmed with Intex that their Sailfish OS phone will not be introduced by them during the event. However, Jolla representatives are showing a prototype of this new phone around Intex booth in Hall 7 while focusing on negotiations in an exhibition meeting room of their own in Hall 2. Intex also shared that they are still unsure on the launch date in India, currently aiming for the first week of May, 2016.
