It was not a great plan
@shawl_who bro? Really? Unlimited data for free? OMG bro, which network are you using right now and what's your plan. I'm really interested to know that.
And, I don't think anyone who tried Jio when it was free ported their primary number to Jio. In fact, It wasn't even available. In fact even now, 90% of the consumers use Jio only as a secondary sim. Consumers are not as dumb as you are thinking, they will ditch Jio if they need to ANYTIME. Don't compare whole of India to poor fishes. Nobody lost concentration and got fooled here as you are saying bro. They got what they needed, first for free and then at dirt cheap rates. You might have forgot what we used to pay for data before Jio. And I'm sure you'll never pay those amounts again in future.
