Airtel Night Plan and Airtel Happy hours both continue to exist and have not been withdrawn, contrary to what is mentioned in the story." Remember Airtel's offer of 50 per cent data back announced last year? The service allows customers to get 50 per cent data back for all in-app content downloads scheduled between 3am and 5am. This service allowed customers to get back 50 per cent of the data that they consumed between 12am to 6am. This is in addition to Happy Hours service announced by Airtel last month.
