Bharti Airtel expects "tariff repair" to drive a significant improvement in Average Revenue Per User (ARPU), and although there has been organic growth in ARPU, the real progress will come from tariff adjustments. Gopal Vittal, Managing Director of Bharti Airtel, emphasized that it s not a matter of if tariff repair will happen, but rather when. He also highlighted the various organic levers that have contributed to the improvement in ARPU, such as postpaid plans, data monetization, international roaming, and higher price plans.
