The Indian telecoms giant, Reliance, is offering smartphone users what it says is the cheapest mobile data network in the world.
The arrival of Jio – the new mobile network – has ramped up the battle among Indian telecoms firms to win customers.
High-speed 4G internet is by no means new to the country, but Jio is offering it at prices well below its rivals.
The company says it hopes to reach 90% of India’s population within a year.
The ambitious plan is backed by the country’s largest private sector firm, Reliance Industries.
Chairman Mukesh Ambani recently used the firm’s annual general meeting to announce his plans for Jio’s 4G services.
It has taken them six years to set up the infrastructure for Jio.
