^ You're right. Completely slipped my mind that the jio sim needs to be in lte mode as well as the active data sim. In my redmi 2 prime, even if you set the alternate slot to 2g only mode, as long as it is the active data slot, the other slot (jio) will remain on 2g. this is more of a phone/chipset implementation issue than jio or lte.
Not sure how a dual 4g sim slot phone would play this scenario out.
