Airtel best prepaid plans with extended validity, unlimited calling for less than Rs 500 — check full list

Airtel has silently launched a new Rs 279 prepaid plan with extended validity and unlimited calling in India. It comes with up to 45 days of validity. Not just extended validity, the Rs 279 plan has the benefit of unlimited voice calling. The catch is, just like other prepaid plans with extended validity, the Rs 279 plan, too, comes with very little data. Airtel will give you only 2GB of lump sum data with this plan. If you want to get more data, you’ll have to invest in separate data vouchers.
