“We are at a premium (in terms of tariff hike). In the telecom space, you can have a premium but it becomes unsustainable after a point. We do not want to slow down our growth,” Vittal was quoted as saying by Mint. Also Read - Reliance Jio Says Receiving Port Out Requests, Alleges Airtel, Vodafone Running False Propaganda

Saying that the telecom operator will continue to focus on serving quality 4G customers, Vittal said Airtel is studying the low-cost smartphone space and added that the telco is yet to decide on an approach and is focusing on migrating its 2G/3G customers to 4G network.

As per updates, Airtel recorded a growth of 14.4 million in 4G user base at 152.7 million during the quarter, up 48% from a year ago.

Notably Airtel now has 440 million users in 16 countries. Airtel’s Arpu has gone up to Rs 162 during July-September from Rs128 a year ago, and Rs 157 in the June quarter.

During the conference call, Vital highlighted that the rollout of 5G technology will take a few more years as India has an underdeveloped ecosystem.

He further added that the reserve prices for spectrum enabling 5G services are unaffordable, and act a deterrent for 5G implementation.
