Even though it is free, the pack has a 4G data cap for 30GB due to Fair usage policy, after that speed will be reduced.
Last month Airtel launched Mega Saver Packs for prepaid customers across India that offered customers enjoy 1GB 4G/3G recharges for just Rs 51 over a period of 12 months by paying Rs. 1498.
The new pack is currently available in Delhi and will be launched across other circles over the next few days.
