Facebook has faced criticism for launching the platform as it is seen as violating the principle of net neutrality, which is against any priority being accorded to an entity in the Internet traffic flow because of payments to service providers such as telecom companies.
"We have 800,000 Internet.org users in India in just the supported seven circles. Internet.org is helping people connect to the Internet for the first time," a Facebook spokesperson said.
About 20 percent of Internet.org users were previously not active on mobile data and thus, Internet.org is bringing new people online, the spokesperson said.
Internet.org service is available for Reliance customers in seven telecom circles of Mumbai, Maharashtra, Gujarat, Andhra Pradesh, Chennai, Tamil Nadu and Kerala.
Internet.org claims to have made Internet available to over 800 million people in nine countries, including India.
