Which is better for you, an Airtel SIM or a Jio SIM?

It depends on the place you have been living. Both are good but jio is purely 4G whereas Airtel is a unified network service means whichever the type of sim, 2G,3G,4G,5G you are using in your phone, it works accordingly. But Airtel prepaid plans recharge rates are High compared to the jio and in cities and towns jio works much faster than Airtel.
