I am using vodafone when I got my first mobile about to 5 or 6 year now.that days you have only 2g connectivity so everyone had manage on that and they are pretty statisfied with that we can use rarelly 100mb data a day, but nowadays 100data is nothing whem here come the jio which have completly ruin other operators with there great plan services.
But vodafone not inproving there networks and give us only 3g and its barelly get speed upto 1mb but compare to jio , jio now giving there services and install there towers in very rural area and villages but vodafone is doing nothing and not giving any good offers and just trying copy jio if jio increase there price then vodafone also increase there price but not giving offer like jio.
