In a new report, Airtel is offering unlimited calls and 1GB/day at Rs 399 for prepaid users. This offer is not open to all users though, and is available for a selected bunch. Activating the offer is rather easy.

Update: There’s another related pack at Rs 499 which offers 1.25GB per day instead of 1GB per day as on the Rs 399 pack.

The offer enables users to make unlimited calls to all mobile networks in India, local and STD, for 70 days and bakes in 1GB/day 4G data for free. The data is not divided between day and night. Users can redeem the 1GB value anytime through the day. Free SMS and free outgoing calls on national roaming are revoked though on this plan.

To activate this offer, launch the MyAirtel mobile app on your smartphone to see if this offer is listed on the app. You can use the app to checkout this deal, or you can dial *121# on the same Airtel mobile number to get it activated.
