Four of Europe's largest mobile network operators have moved to build a carrier-led alternative to SpaceX's Starlink direct-to-cell service. Deutsche Telekom, Orange, Telefónica and Vodafone signed a letter of intent on October 19, 2026, saying they are considering a joint bid for spectrum that would underpin European direct-to-device satellite competition. The arrangement deliberately splits the stack: the operators would own and run the ground segment, while a separate, as-yet-unnamed satellite partner supplies the constellation.

A split ground-and-space architecture

The division of labour is the most consequential technical detail. Under the plan, the four operators would establish key ground network infrastructure in Europe along with the coordination and monitoring functions needed to operate a direct-to-device service. They would not invest directly in a satellite constellation; that would come from a satellite partner still to be selected. The group argues the pairing combines European governance and market access with proven satellite deployment expertise.

The stated ambitions are broad: meeting customer demand for universal coverage in underserved areas, strengthening the resilience of public networks, protecting critical communications, and supporting the development of a European constellation. For engineers, that framing points to a service designed to complement terrestrial coverage rather than replace it — filling rural gaps and providing fallback capacity when ground networks are degraded or unavailable.

Why spectrum is the battleground

Direct-to-device service depends on radio spectrum that can serve both satellites and ordinary handsets, making the joint bid the commercial heart of the announcement. In May, the EU said it was considering a plan to reserve part of the 2 GHz band for local companies to offer satellite services. SpaceX has criticised that idea, claiming it would worsen service in Ukraine. The four-carrier initiative appears positioned to take advantage of exactly that kind of European spectrum reservation, tying market access and governance to the continent's own operators.

That is also where the hardest engineering questions sit. Direct-to-device links must close against the power, antenna and thermal limits of unmodified smartphones while satellites move overhead at orbital speed, requiring tight coordination between constellation design, ground stations and the operators' core networks. Handing the ground segment to carriers that already run national radio access and core infrastructure is a credible way to manage that complexity — but it makes the choice of satellite partner decisive.

A transatlantic pattern

The move mirrors a similar collaboration in the United States, where AT&T, T-Mobile and Verizon announced earlier this year that they would combine spectrum in rural areas and dead zones to increase capacity, improve customer experience and help satellite providers reach more customers through a unified platform. In both cases, terrestrial operators are trying to avoid being reduced to resellers of a single satellite provider's connectivity, instead controlling the spectrum, the ground network and the customer relationship.

What happens next

The letter of intent is a statement of intent rather than a binding commitment, and the satellite partner has not been named. The immediate milestones are the spectrum bid and the selection of a constellation operator capable of rivaling SpaceX's scale. Europe's broader goal — a homegrown constellation backed by European governance — remains the long pole, since a satellite partner must bring both proven technology and deployment capacity. For developers and IT teams, the practical signal is that direct-to-device connectivity is converging on a hybrid model: carrier-owned ground infrastructure, satellite-provided radio access, and European spectrum policy shaping who gets to compete.
