As I have already mentioned, people consuming good amount of 5G data without reliable Wifi access will move to higher end plans. The ones needing less data will have to look elsewhere. Again India is not limited to Navi Mumbai.I agree with second para, but I don't agree with first para.
Those who used to recharge with 1599 or 1449, unlimited voice calls and 24GB data have shifted to 3599 after July tariff hike. I think @Esmail had that plan in his OnePlus Nord 3, he might have shifted to 3599 as well. That's my experience at distributors of Airtel prepaid in Navi Mumbai.
Everyone has a different usecase and not everyone needs Unlimited 5G.
