T-Mobile and SpaceX have announced that Starlink satellites launched next year will be able to connect directly to the carrier’s phones over existing cellular bands. The companies hope to enable global roaming wherever satellite coverage exists, and the service may potentially be added for free to existing T-Mobile plans.

SpaceX’s Elon Musk and T-Mobile’s Mike Sievert announced the “technology alliance” at the space company’s Starbase in Texas.
