The company has withdrawn discounts that it was offering for online purchase of mobile data packs, bringing the prices at par with Internet packs sold offline through retailers.
"There is a slight change in few of our online prepaid data packs owing to the discontinuation of discounted offers on these," an Airtel spokesperson told PTI.
Also, sources said that Airtel has raised prices of 10 data packs.
For instance, earlier, the company used to offer 2GB of 2G data for Rs. 199 with a validity of 30 days if the recharge was done online. It has now been changed to 1.25GB of data with 28 days validity.
In case of 3G, the company is now offering 1GB of 3G data with 28 days validity for Rs. 255 against charge of Rs. 249 for the same data usage with 30 days validity.
Last week, Idea Cellular hiked mobile data rates for prepaid customers in the NCR region, becoming the first telecom operator to raise the tariff after the Rs. 1.1 lakh crore spectrum auction in March.
In a bid to improve profitability, telcos have been cutting back on discounts and freebies. Last year also, firms including Bharti Airtel, Vodafone and Idea had increased data as well as call tariffs.
After the March spectrum auction, industry associations had said there would be hike in tariffs as operators have to meet the commitment to the government.
