AST SpaceMobile is potentially a telecom infrastructure company hiding in the space sector, with a far bigger market than rocket makers like Rocket Lab. It is building a space-based cellular network that could connect the billions of phones already in use directly to satellites almost anywhere, from rural areas and oceans to dead zones and disaster areas, with no dish, special hardware or new phone. Rather than compete with telecom companies, it partnered with AT&T, Verizon and Vodafone. x.com
