As there is many mobile operator in india but Airtel has big part of it befor Jio. I am use Airtel as my primery sim since 4 year’s in 1-2 year’s there was teriable network coverage but have to stike with it because have given this number to my important contact.Since when Jio has came than we got to know that Airtel was lotting up last few year’s .In terms of call quality , network is nice now a day’s
But the internet speed is not that fast on 4g as jio has
