"Facebook isn't a company that hits a roadblock and gives up," he said at the Mobile World Congress in Barcelona on Monday. "We take the hits that we get and try to learn from them and just do better."
Zuckerberg outlined the progress of the Internet.org initiative, through which he hopes to expand Internet to billions of people who lack access. Free Basics, a key package that offers only select services including Facebook, operates in 38 countries and has brought access to about 19 million people, Zuckerberg said.
Regulators in the world's second-most populous country banned the service this month in a blow to Facebook. Free Basics has taken criticism for its potential to block out smaller content providers and start-ups who do not participate.
