I am not talking about that. I am talking about Jio focusing on ARPU. Evil face of Jio will start coming infront of people. If Airtel is evil, then Jio is double evil. That's what I wanted to convey.
Coming back to your point, if Jio doesn't allow for users to do outcoming calls without recharge, why should Airtel remain behind in this regard? As simple as that. Airtel has most number of active customers and it will increase from this point, no matter what Jio keeps the tariffs for 4G after Airtel hikes the tariffs at the end of the year or no matter what Jio keeps tariffs for 5G. If Jio doesn't provide unlimited data at capped speeds on 5G,then people will shift to Airtel/Vi within no time. Jio network will be empty then and Jio will have to bring various attractive plans again to poach high value customers and this will create problems for investors. No monetization of apps yet. Let's see how much far Jio can go.
