Everything depends on the onboarding cost. If they launch it at a correct price with some lucrative trial offers(which is unlikely), they will be able to get a lot of users atleast to try it even if not retaining customers. My guess is that pricing will be similar to Jio Fiber plans, slightly less maybe but the cost of CPE and external unit will be on the higher side. Let's see what strategy Jio has this time.
Might try it out if the pricing is right. It may act as a secondary ISP/backup for me.
