AT&T and AST SpaceMobile Announce Industry-First Terrestrial-to-Satellite Handoff

AT&T and AST SpaceMobile have announced the industry's first successful handoff between a terrestrial cellular network and a direct-to-device satellite connection, completed with a standard smartphone via an AST BlueBird satellite. The milestone was achieved on 21 October 2026 in Granite Falls, Washington, and was publicly announced in early November, as covered by Telco Magazine. It follows the companies' earlier tests of satellite voice, SMS and video calls.

Direct-to-device technology allows ordinary handsets to connect to satellites when terrestrial coverage is unavailable, moving the approach from demonstrations toward practical network architecture. In the same weekly round-up, T-Mobile reported that SIM-swap fraud attempts have fallen more than 99 percent since 2022, crediting biometric verification and port-out protections; this is a company claim.

No commercial beta schedule for the AT&T service has been announced. For archipelago markets such as Indonesia, satellite direct-to-device connectivity is viewed as a potential future coverage option, though no domestic regulatory decision has been made.
