Helllo everyone I have been using airtel since last one year and I found it normal .not excellent but able to satisfy the needs .the networks are availaible almost the entire areas where you go that is the best part of the service however connection is still not so strongs .also the airtel 4g lte is quite expensive than others. also the speed is not good as expected as compared to airtel 3g. I recommend you for airtel 4g lte but not people of remote areas.
