Copying is helping them. Almost all plans they have copied from Jio and they haven't invested anything, like double data offers in Vi prepaid in 2021, night unlimited. Later Vi brought same thing to postpaid as well. Vi brought unlimited 4G data plan in postpaid and Jio copied it. Now before 5G, it was selling well and later with unlimited 5G, people downgraded their plans to 199 plan. Airtel haven't done anything copy in postpaid segment. But they have literally copied since last three four years in prepaid segment and keeping 50-100 rupees higher plans, because their 4G was best in 2019-2022 era. Now, they have not copied unlimited plan in postpaid because Airtel doesn't have capacity to serve customers. Airtel gained, not because Vi was bad, Airtel gained because Airtel focussed on network from 2017-2019 and after 2019, their customers just shoot up like nobody else. Airtel already had band 3 spectrum more than Jio and has leverage of using band 1 to their full potential. Today Airtel is lacking four things. First of innovation, if they could slash fiber prices to 30%, then their FTTH customers will double. But simply they are not doing it. Airtel customer service is worse for single postpaid user(It's still better than Jio postpaid/Jio fiber), but it's not good enough. That's where Airtel black remained behind. In my city, Mumbai, People still using Vi Postpaid and Tata Fiber in South Bombay, when Airtel fiber is actually lot better. Jio ecosystem is good, but once fiber cuts happen, Jio isn't quick to fix things up. Airtel quickly resolve things if you are on 200-300Mbps plan(atleast my personal experience in Mumbai). Airtel just messed up everything since two years since 5G launch. Now they are focussing on 4G expansion(actually that's the thing they should have done two years back when 5G was not necessary). Now 4G would have been perfect by Airtel with more 4G coverage and would have ended Vi completely. There was spectrum cap on N78. Jio would have taken maximum of 150Mhz only. There was simply no need to rush. I hope Airtel fixes everything in next three years along with slashing FTTH prices and fiber backhaul to their 4G/5G towers. But I feel it's too late now.
