How satellite-to-phone services work
Direct-to-device satellite service aims to make an ordinary 4G or 5G phone connect when no terrestrial mast is reachable. The satellite acts as part of the mobile radio network, while the customer's usual operator can retain the subscription, identity, core network, and spectrum relationship. This is different from carrying a dedicated satellite phone or installing a Starlink-style dish.
One strongly European path pairs Luxembourg-based OQ Technology with Telefónica Germany. In June 2026, the companies announced work in Mecklenburg-Western Pomerania using Telefónica's frequencies and OQ's low-Earth-orbit payloads. The planned demonstration targets two-way text and voice messaging with conventional, unmodified smartphones. Telefónica described live testing over the following year, so the announcement should not be mistaken for a nationwide commercial service already switched on.
OQ brings satellite and 5G non-terrestrial-network experience; Telefónica brings licensed spectrum, customers, terrestrial infrastructure, and network operations. That pairing illustrates why mobile operators are central. A satellite signal must coexist with national frequency rights, avoid harmful interference, authenticate customers, hand over to ground networks, route emergency communications, and produce a service operators can support and bill.
Other networks, demonstrations and standards
A second path is Vodafone's joint venture with US-based AST SpaceMobile. The partners created a European satellite service company, commonly described as SatCo, intended to sell a turnkey direct-to-device service to mobile operators across Europe. Vodafone supplies European network and operations expertise; AST supplies the space-based cellular system. The venture has a European operating structure, but its satellite technology partner is American, so it is not a wholly European constellation.
The technology has passed meaningful demonstrations. Vodafone and AST reported a space-based video call in January 2025 from an area without terrestrial mobile coverage using an ordinary commercial handset. Commercial coverage, capacity, indoor performance, emergency integration, pricing, regulatory approval, and service availability are different milestones. A successful call proves a link; it does not prove that millions of phones can receive dependable broadband at once.
ESA and the mobile industry are also building common capability. In March 2026, ESA and the GSMA Foundry opened calls offering access to up to €100 million from participating ESA member states for projects covering artificial intelligence in non-terrestrial networks, direct-to-device systems, 5G/6G testing hubs, and 6G innovation. This is ESA-member-state funding, not automatically an EU budget line or one procurement for a single operator consortium.
Spectrum, IRIS² and the practical limits
The European Union's role is particularly important in spectrum. In May 2026, the Commission proposed an EU-level process to select providers allowed to use the harmonised 2 GHz mobile-satellite band after current licences expire in 2027. The proposal is meant to make cross-border authorisation more consistent. As of this review, it remains a proposal: providers have not won future EU-wide rights merely by announcing a service.
IRIS² is related but distinct. The EU's secure-connectivity programme has a 12-year concession with the SpaceRISE consortium of SES, Eutelsat, and Hispasat, supported by telecom and aerospace companies including Deutsche Telekom and Orange. It is designed for secure governmental and commercial connectivity through more than 290 satellites across several orbits, with governmental services targeted by 2030. It should not be described as an ordinary-phone D2D service already available today.
The near-term value is targeted coverage: emergency messages, rural roads, mountains, islands, maritime areas, disaster zones, and temporary terrestrial outages. Satellites will complement fibre and mobile masts rather than replace them. They have constrained radio power and shared capacity, need a view of the sky, and cost far more per delivered bit than dense terrestrial networks.
Europe can be proud that its operators, satellite companies, institutions, regulators, and standards engineers are working on the full stack instead of treating connectivity as only a spacecraft problem. The next honest scorecard should ask which trials happened, which frequencies were authorised, which satellites launched, which operators signed commercial contracts, what standard phones can do, and where a normal customer can actually buy the service.
