India's telecom tariffs are among the lowest in the world as a percentage of per capita gross national income (GNIpc), with telcos having the potential to raise prices by at least 1.5x over the next 4-5 years. India's tariffs are the second lowest among countries with a GNIpc of less than $10,000, after Brazil's 0.92%. Analysts predict sharp tariff hikes by telcos like Reliance Jio, Bharti Airtel, and Vodafone Idea in 2024, as they are preparing to roll out their 5G services.
