AST SpaceMobile: Space-Based Internet for Every Phone

87% of Earth's surface has no mobile coverage. AST SpaceMobile is building the world's first space-based cellular broadband network that connects any standard smartphone, anywhere on Earth, without modification.

The Coverage Gap Nobody Fixed

Five point eight billion people use mobile phones. Two point two billion of them cannot access cellular broadband. Not because they do not have phones. Because 87 percent of Earth's surface has no mobile coverage at all. Oceans, mountains, deserts, rural communities, and remote regions sit completely outside the reach of traditional cell towers. The infrastructure required to close that gap through ground-based networks would take decades to build and cost more than any commercial model can support. AST SpaceMobile is building the answer from space instead.

BlueBird Satellites: Broadband Direct to Your Phone

The SpaceMobile Network is built around BlueBird satellites that deliver full broadband directly to standard smartphones. No special device. No hardware modification. No new app. The phone already in a person's pocket connects to the SpaceMobile Network exactly as it would connect to a ground-based cell tower, at 4G and 5G speeds, from anywhere on Earth. Video calls, web browsing, and everyday apps all work normally. The network is designed to integrate seamlessly with existing mobile operator infrastructure, meaning coverage gaps disappear for subscribers without any change to how they use their phone or which operator they use. AST SpaceMobile has partnered with over 50 mobile network operators representing nearly three billion combined subscribers, including AT&T, Verizon, Google, Bell, Rakuten, and STC.

One Network, Every Environment

The applications of space-based cellular broadband extend across every environment where ground-based coverage fails. Remote rural communities gain access to healthcare, education, financial services, and employment opportunities that connectivity unlocks. Emergency response teams coordinate rescue and relief operations when terrestrial networks are damaged or destroyed. Maritime crews stay connected and operate safely throughout journeys that take them far beyond coastal coverage. Agricultural operations in remote areas have access to real-time data on weather, crops, and market prices. In-flight passengers connect from takeoff to landing without dedicated aircraft Wi-Fi systems. Defence operations coordinate securely in challenging environments where traditional infrastructure cannot reach. The same network serves all of these simultaneously.

A Mission Built Around the Unconnected

AST SpaceMobile's stated mission is to eliminate the connectivity gaps faced by today's mobile subscribers and bring broadband to the billions who remain unconnected. The BlueBird satellite constellation is designed to achieve global coverage, with each generation of satellites expanding both capacity and reach. The Next Gen BlueBird programme advances the network further, increasing performance and coverage density as the constellation grows.
