No they have actually discontinued lower priced plan in NCR region.
Same strategy as with mobile sim plans. They r concentrating on limited high value customers for high revenue. They don't want low value customers since they r not giving them enough revenue and at the same time clogging the network. Now they will compete on quality. In any case Airtel knows that these entry level customers will b first to switch to Jio.
This is as per my talk in Airtel..
