What happened
In 2016 mobile data in India was expensive and most users rationed it. Reliance Industries built Jio as an all-4G network from scratch, investing well over ₹1.5 lakh crore, and launched commercially in September 2016 with free data and calls until March 2017.
Jio signed up about 100 million subscribers in roughly 170 days. Even after it began charging, data prices were far lower than before; average data cost per GB in India fell steeply and data use per user multiplied. Voice calls became free for good. Rivals were forced to cut prices; several smaller operators exited, and Vodafone and Idea merged in 2018.
In 2020 Jio Platforms raised about ₹1.5 lakh crore from investors including Facebook (about $5.7 billion) and Google (about $4.5 billion). Jio became India's largest telecom operator, with over 450 million subscribers.
