"We just launched Internet.org in India -- giving people in six Indian states access to free basic internet services for health, education, jobs and communication," Zuckerberg said.

"Over the last year we've rolled out Internet.org free basic services to countries with more than 150 million people total across Africa and Latin America. More than 6 million people are already connected to the internet who previously weren’t, and we’ve started hearing incredible stories about how the internet is changing lives and communities," he wrote.

"But to continue connecting the world, we have to connect India. More than a billion people in India don’t have access to the internet. That means they can’t enjoy the same opportunities many of us take for granted, and the entire world is robbed of their ideas and creativity," he said.

"Today’s announcement is just one step towards changing that. People on the Reliance network in the states of Tamil Nadu, Mahararashtra, Andhra Pradesh, Gujarat, Kerala and Telangana will now have free data access to more than three dozen services, Zuckerberg said.

"We still have a long way to go to connect India. But I'm optimistic that by getting free basic services into people's hands, more change can follow pretty rapidly," he said.
