But they did not pay me for this post
It's different story in some other places, Jio is better and Airtel is worst. Some areas have great Airtel speeds but worst Jio speeds.
I use both Jio and Airtel, Jio speeds did decrease as more users started using Jio but on other side Airtel which has been here from decades still is unable to provide consistent service. So both are not perfect for me.
In some other places Vodafone comes winner among all like in Bengal where Vodafone provide best speed 15-20 Mbps then comes Airtel 8-10 Mbps . Jio comes last with 4-7 Mbps . Coverage wise rank is also same. Vodafone leads whereas Jio comes last
