VodafoneThree’s Satellite-to-Smartphone Service Moves Closer to UK Trials
VodafoneThree has cleared a key regulatory hurdle for a planned satellite-to-smartphone service in the UK, with customer trials expected later in 2026.
VodafoneThree’s planned satellite-to-smartphone service in the UK has moved closer to reality after a regulatory decision cleared the use of 900MHz spectrum for direct-to-device connectivity. The service is not commercially available yet, but VodafoneThree says customer trials are planned later in 2026.
The announcement follows Ofcom’s approval of a licence variation allowing VodafoneThree to use part of its existing 900MHz spectrum for satellite connectivity. In a subsequent regulatory update, Ofcom explained that new licence-exemption regulations would support mobile handsets and SIM-enabled devices connecting to direct-to-device satellite services in specified 900MHz frequencies.
This distinction matters because the regulatory decision is an enabling step, not a consumer launch. VodafoneThree has not announced a commercial release date, pricing, trial registration process or complete list of compatible phones. Those details are expected to become clearer as the operator moves towards testing the service with customers.
VodafoneThree says the planned network is intended to provide more than a limited emergency link. The company describes a service capable of supporting data, voice calls and SMS messages through a connection between compatible mobile devices and satellites. That could give people a way to remain connected in parts of the UK where terrestrial mobile coverage is unavailable or where installing a conventional mast would be impractical.
The satellite connection will use AST SpaceMobile’s low-Earth-orbit satellites. A supported smartphone will connect to a satellite above it, which will then relay the traffic to VodafoneThree ground infrastructure. From there, the connection will pass through VodafoneThree’s core network and reach the wider internet through fibre connectivity. In practical terms, the satellite link is intended to extend the operator’s existing mobile network rather than create a separate messaging application or isolated communications system.
The choice of 900MHz is also significant. Lower-frequency spectrum can travel over longer distances than higher-frequency bands, making it useful for connecting broad rural areas. VodafoneThree says the relevant spectrum was previously used for 3G services and can now be reused as those older networks are retired. Ofcom’s decision allows that existing licensed resource to support a new form of connectivity without requiring every uncovered area to receive a new terrestrial mast.
For rural users, the service could eventually provide an additional layer of coverage in locations that are difficult or expensive to reach with ground infrastructure. VodafoneThree presents the satellite network as a complement to the mobile network already being built on land, including coverage delivered through conventional sites and the Shared Rural Network. It should therefore be viewed as a way to fill selected coverage gaps, not as a replacement for the operator’s wider 4G and 5G rollout.
The exact user experience will depend on the final service design. VodafoneThree has not yet published a definitive list of supported smartphone models, geographic restrictions or the conditions under which calls, messages and data will work. Device compatibility, SIM support, network configuration and the availability of a suitable satellite connection will all need to be confirmed before customers can rely on the service in everyday use.
The company has already demonstrated the underlying idea. Vodafone says it completed its first space-based video call using an ordinary 4G or 5G smartphone in January 2025, in an area without terrestrial mobile coverage. That demonstration showed that satellite-to-device communication can connect with existing mobile technology, but a controlled demonstration should not be confused with a fully deployed consumer service.
Ofcom’s decision gives VodafoneThree and AST SpaceMobile a clearer route towards real-world testing. The next meaningful milestone will be the customer trials planned for later in 2026, when the partners can assess how reliably the service works outside laboratory conditions and across different locations. Until those trials produce more information, the announcement should be read as a regulatory and network-development milestone rather than a promise of immediate satellite coverage for every UK smartphone.
