Airtel is said to have refreshed its Rs. 149 prepaid pack to now offer double the data than its previous revision, in an attempt to take on Jio wreaking havoc in the Indian telecom industry. The Rs. 149 Airtel recharge now gives subscribers a daily limit of 2GB of 3G/ 4G data with a validity of 28 days. This takes the total amount of data offered to 56GB of data at a per GB cost of Rs. 2.68. Airtel also offers unlimited voice calling (local, STD, and roaming) and 100 SMS messages per day.
