Mr. Ambani's Jio company is targeting both ends of the pyramid. It is investing $25 billion on a 5G network coming in late 2023. At the lower end a new $12 mobile phone calld JioBharat by India's largest telecom provider aims to reach 250 million people who use 2G mobile phones. Mobile phone penetration in India is about 46% in 2021, up from 17% in 2016, according to World Bank. This is largely due to the efforts of Mr. Ambani who built a 4G network from scratch and has 440 million subscribers with some of the lowest data rates in the world. The new phone has a smaller screen, physical keyboard, camera and runs on 4G.
