Vodafone Idea reported a smaller loss of Rs 7,176 crore in the September quarter, helped by tariff increases that boosted revenue to Rs 10,932 crore. Despite an 8% rise, its ARPU of Rs 166 still trails rivals Jio and Airtel. The company’s user base shrank to 20.5 crore, leading to a network expansion drive to improve 4G coverage and speeds.
