I have both the sim jio and airtel but I noticed that jio give less speed than airtelAnd jio have less network than airtel. Their are many place were jio network not reach in that places .And I am also belong to that place were jio network not reach .That why I have to use airtel and Iam noticed that airtel network reach all about every part of India airtel have more faster internet speed than jio . Jio have less recharge price than airtel .For good and high speed internet network you should use airtel
if they want to buy jio sim so they can buy. I want to say airtel is better than jio .but jio is not a bad sim you can use
