Its been seven months I am using Jio sim& not even a single day I had any network issue, Netspeed issue, not even in Roaming, but as far as Airtel is concerned I had this problem consistently, Network is some how considerable, but Netspeed being 4G, I had regular speed drop issues, Again I am not saying after Fair usage policy, within the deadline of Fair usage policy& I never ever got right network connectivity in Roaming, As I am regular traveller, I needed a network with the strong connectivity in roaming.
postpaid services of Airtel is another Major issue with them, I had no clearity of what I was getting Charged for.
