A global partnership dedicated to making affordable internet access available to the two thirds of the world not yet connected

Internet.org 1.

Apps for the Entire World The Internet.org Innovation Lab, an Ericsson-Facebook collaboration, was designed to help developers understand how their apps will work in different parts of the world. The lab’s elaborate test environment mimics a variety of network conditions, giving developers a way to ensure their apps will run even in very remote areas.Learn more.

Developers will be able to start using the lab, located at Facebook’s Menlo Park, California headquarters, beginning this summer.Contact the lab.

Taking Connectivity to the Next Level The Connectivity Lab at Facebook is developing ways to make affordable internet access possible in communities around the world. The team is exploring a variety of technologies, including high-altitude long-endurance planes, satellites and lasers.

3.

Providing Access to Free Basic Services The Internet.org app provides free basic services in markets where internet access may be less affordable. It allows people to browse selected health, employment and local information websites without data charges. Initially launched to Airtel customers in Zambia, the app will continue to expand into other parts of the world.
