In a blog post released to mark the first year of the initiative, Facebook said it will open a portal allowing any mobile operator to offer the service under its Internet.org platform. Facebook currently partners with specific operators to launch the service in different countries.
Internet.org has brought over 9 million people online over the past year, Chris Daniels, vice president of product for Internet.org, told on Monday. Facebook developed the platform with six technology partners to bring an estimated 4.5 billion unconnected people online, mainly in Latin America, Asia and Africa.
It offers pared-down web services for free to users, along with access to Facebook's own social network and messaging services.
Facebook's blog post said that over the past year, the service had bought new users onto mobile networks on average over 50 percent faster and that more than half the people using Internet.org are paying for data to access the wider Internet within 30 days.
"This is really a customer acquisition tool for mobile operators where the benefit to them of offering a very light amount of free data is to bring on more paying subscribers to their networks," Daniels said, speaking over phone from Nairobi, where he is attending a summit.
Facebook was not paying for any of the data being used to access the service, he said.
The Internet.org application, launched in India in February in partnership with Reliance Communications, faced backlash with a number of leading technology and Internet firms pulling out of the service after activists claimed it violated the principles of a neutral Internet.
"I would say India is unique in that respect and very much an outlier. In other markets, Internet.org has been embraced as a pro-connectivity initiative that has garnered a lot of support," Daniels said.
A committee of the telecoms ministry set up to examine the issue of net neutrality earlier this month recommended that collaborations between mobile operators and content providers that enable "gatekeeping" roles should be discouraged.
