Charting the concerns of the customers, Mr Vittal said: "First, unused data that expires at the end of the month is seen as a painful waste. Second, customers are looking for a relationship with the service provider for all of their connections. Third, the security of their devices and the privacy of their data is critical. Finally, an upgrade from prepaid to postpaid is a cumbersome experience."
"Airtel postpaid customers no longer need to worry about losing unused data at the end of the month. In an industry first, starting August 1, 2017, all Airtel postpaid customers will now be able to carry forward their unused monthly data quota to the next billing cycle," he added.
The company said postpaid customers can now create customised solutions for the family by adding multiple postpaid connections to their account, and enjoy savings of up to 20 per cent.
The company also introduced 'Airtel Secure' - a digital smartphone protection suite - through which customers can now protect their smartphones against accidental/liquid damage.
Airtel Secure also comes with Norton Mobile Security Suite, which includes anti-malware protection, and an App Advisor that flags privacy risks such as intrusive behaviour.
As part of the project, the company will revamp all its 2,500 stores across the country. The next-gen Airtel stores have been conceptualised by the UK-based 8 Inc. The first two stores are in Gurgaon.
The company's shares in the BSE closed at Rs 405.40, up 5.39 per cent, on Monday.
