China has achieved a major breakthrough by completing a real-time 5G video call directly between a satellite and a standard smartphone. This milestone allows for high-speed data transmission without relying on mobile towers, ground stations, or external antennas. The technology utilizes a Non-Terrestrial Network (NTN) to connect regular devices to Low Earth Orbit (LEO) satellites. These satellites act like "cell towers in space," providing broadband-level connectivity even in the most remote are
