satellite phones

Satellite phones are mobile communication devices that connect to satellites orbiting the Earth rather than relying on terrestrial cell towers. This allows them to provide voice and data services in remote or underserved areas where traditional cellular networks are unavailable. Satellite phones operate by establishing a link with overhead satellites, which then relay signals to ground stations that are connected to the public telephone network. They are commonly used in situations where reliable connectivity is crucial, such as in emergencies, expeditions, maritime operations, or by professionals working in isolated locations. Due to their satellite-based communication, these phones can often be used globally, regardless of geographical barriers.
