Airtel, Idea and Vodafone seems to have killed unlimited/long-term validity prepaid recharges

In my opinion, Airtel, Voda and Idea should stop advertising on billboards, TV, etc. and instead use that money on strengthening their network with more towers. The best advertisement these days is thru word of mouth. Clearly Jio is getting more users because they keep strengthening their network
