Bharti Airtel reported a strong 12% revenue growth in the September quarter, outpacing peers and gaining 70 basis points in market share due to a better subscriber mix and improved pricing. Average revenue per user (ARPU) rose 10% year-on-year. While Reliance Jio grew 10% driven by subscribers, Vodafone Idea saw slower growth and continued subscriber losses. The sector is seeing a shift in growth from urban to B/C circles.
