Ok bro I don't know how much Karnataka you explored i got seamless connectivity because of Jio.Jio have terrible network in Karnataka, I was travelling and experienced worst coverage this week even in cities while airtel still had better connectivity
Seems Jio is loosing it's hand in South India and Airtel is grabbing attention.Same other way round also was there until few weeks ago. Kerala situation is even worse than Bangalore. There VoLTE drops once every 2 hours. I got my mom ported out of Jio into Airtel Black..
Airtel is infinitely better, VoLTE is more reliable and available.
I think Airtel 5G will be more superior than Jio 5G.
