AST SpaceMobile is developing a space-based cellular broadband network using large phased-array satellites in low Earth orbit that can connect directly to unmodified smartphones without requiring specialized equipment. The company partners with mobile network operators rather than selling directly to consumers, offering voice, text, data, and video services to customers outside terrestrial coverage through a revenue-sharing model in which operators market the service as an add-on to their existing plans. AST SpaceMobile generates revenue through service agreements with mobile operators, government contracts for satellite testing and mission-critical applications, and gateway equipment sales to operators for ground infrastructure integration.
