The entry of Jio, from a consumer point of view might seem great, but even Jio shot itself in the leg to try and seem consumer-friendly. A simple example
There was a time when tele-advertisement was permitted only from telecom-operator provided special numbers and strictly regulated too. Today any chap can get a SIM with unlimited calls, put them in a small portable device, hook it up to a computer running software and make as many calls as possible before the SIM is banned. None of this creates any revenue for the operator.
