My prediction:
Rs.599 - 100mbps upto 500 GB
Rs.999 - 100mbps Unlimited
Unlimited calls, Free Jio apps and services and many more.
It is sure that like telecom they will not start Giga fibre with zero or very cheap plans.
I think they will have iptv. There is no use of broadband without entertainment. They will have iptv, movies, prime, netflix everything. They will destroy the young market in cities. Only small places where there is no fiber, people will pay to get dth/cable.
BASIC PLAN: Rs.599 - 100Mbps upto 100GB and unlimited thereafter at 2Mbps - Jio Home TV Subscription - Access to Jio Apps - Free Landline Phone with Unlimited calls all over India
Basic won't be basic if they give 100 Mbps in it. Rather 50 Mbps looks dencet for entry plan and they also plan like that which is why they launched the Rs 2500 router already.
