I just hope, RJio won't repeat their (only) mistake during CDMA launch, that is forcing to buy Handset from them only. Even now Moto X Play and Moto X Style has VoLTE support natively (just like Moto G3), but RJio doesn't allow them to be used in their network for VoLTE. They allowed Moto G3, but NOT Moto X Play and Style. Why? It may affect the sales of their relatively higher end Water and Earth models. There can't be any other reasons..
They should just close down LYF phones co and join hands with other phone makers to have infinite options for customers, imho... ELSE, forget Airtel, they can't even beat Idea in telecom business..
