I had a NU 256Kbps and my usage was not metered.Now when I updated to same NU @2Mbps, the usagewas metered leading to confusion.After i contactedNodal Nu 0900PM to 0800AM at @2mbps is not metered.Bangalore CC called me and said it is a simple matterand may be set the counter not to record during NU. I wonder , whether they could be recording it now, and very unlikely.Record unlimited usage, take print out, analyse the dataand then setting limit seems far fetched.I think U/L users need not worry.Till date , Airtel has not changed the usage conditionsof EXISTING customers. Very few are getting NU ,that too at@2Mbps now.
