An LTE phone can connect to a satellite
SpaceX is developing Starlink Direct to Cell, a service in which satellites equipped with an eNodeB modem act like a cellular base station in orbit. A compatible LTE phone does not need an extra antenna or a special app to send a message from an area without traditional coverage.
Early tests included text messages, video calls, and data transmission. The service is being introduced with mobile network partners, and availability depends on the country, operator, and local approvals. It is an important step toward reducing mobile dead zones, although it does not yet replace terrestrial networks for every use case.
This draft is based on technical information published by Starlink about the Direct to Cell service.
