Ookla data: UK becomes the third largest D2D satellite market as O2 Satellite scales

Six weeks into O2 Satellite's commercial launch, Ookla's signal scan data reveals a market that is broad but shallow and a regulatory template that the rest of Europe is watching closely.

When Virgin Media O2 launched O2 Satellite on February 26, 2026, it made the UK the first country in Western Europe where a smartphone could connect directly to a satellite without specialist hardware or a separate SIM. A few weeks later, independent data suggests the market has moved faster than almost anyone anticipated and slower than the headline numbers imply.

Analysis of Ookla’s background signal scan data from UK Android handsets between July 2025 and March 2026 shows the UK has risen to third place globally by unique D2D user count, behind only the United States and Australia, accounting for 11% of all tracked D2D users worldwide. For a densely urbanised island nation six weeks into a commercial service, that is a remarkable result.

But the same data ranks the UK ninth by scans per detected user, with an average of four scans per user in March 2026 against Canada’s 29. That gap is the most analytically significant number in the report.

Broad reach, shallow engagement

What Ookla’s data describes is a market where many users are briefly crossing into satellite-eligible conditions at the edge of O2’s terrestrial network, rather than relying on D2D for extended periods.

The UK’s population density of around 283 people per km² means terrestrial mobile already covers most outdoor premises. D2D in this context is not about reaching vast unserved interiors in the way it is in Australia, Canada, or Chile. It is about filling residual gaps: upland walking routes, coastal roads, operator-specific not-spots, and the rural fringes where O2’s 89% landmass coverage runs out.

O2 itself framed the service around hiking, climbing, water sports, sailing, and rural travel. The early geospatial data fits that proposition precisely. Ookla detected D2D signal clusters in the Scottish Highlands and Outer Hebrides, the Welsh uplands of Powys and Gwynedd, the Southwest peninsula across Exmoor and West Cornwall, and the Yorkshire Dales and North York Moors. These are almost exactly the locations Ofcom’s Connected Nations 2025 report identifies as all-operator coverage blackspots and the same areas the £1.3 billion Shared Rural Network is committed to reaching by January 2027.

D2D is delivering a first layer of connectivity to those locations ahead of the SRN deadline. The caveat matters, however: O2 Satellite does not currently support standard voice calls, SMS, 999 texts, or emergency alerts. It is not interchangeable with Ofcom’s quality 4G standard, and satellite coverage cannot yet substitute for terrestrial mobile in any regulatory or commercial sense.

Regulation shaped the market before technology did

The UK moved first, not because of a technology advantage but because Ofcom moved first. Its December 2025 framework, authorising D2D in mobile spectrum through a handset licence exemption and operator licence variations, was the earliest in any European country. VMO2 received its licence variation on February 17, 2026. The Exemption Regulations came into force on February 25. O2 Satellite launched the following day. The sequencing was that precise.

Ookla’s data captures that regulatory trigger directly. UK D2D activity was negligible until November 2025, when a sharp inflection coincided with VMO2’s employee trial period. A second step-change arrived in February with the licence variation and commercial launch. Regulation, not technology, determined the timing.

A competitive market is already forming

O2’s first-mover advantage is unlikely to hold for long. On April 15, 2026, Ofcom granted VodafoneThree a second D2D licence variation on 900 MHz Band 8, authorising a service over AST SpaceMobile’s BlueBird satellites through the Satellite Connect Europe joint venture. Customer trials are targeted for summer 2026, with commercial launch by the end of the year.

The two services will differ in meaningful ways. VodafoneThree is positioning its proposition around data, voice, and SMS, a more complete offering than O2 Satellite’s current app-based data service. The spectrum positions also differ: O2 on 1800 MHz Band 3, VodafoneThree on 900 MHz Band 8. Real-world performance will depend on satellite payloads, beam design, and device support as much as frequency, but the UK is on course to become one of the first markets where two competing satellite-to-smartphone architectures operate under the same national regulator simultaneously.

BT’s EE, the UK’s largest mobile network, has taken a different path entirely, partnering with Starlink for fixed home broadband rather than handset D2D. That leaves EE without a consumer D2D product as its two largest competitors move, though it positions the operator as a natural candidate for any satellite overlay on the UK’s Emergency Services Network.

What Europe is watching

The EU faces a structurally harder problem. D2D in harmonised mobile bands is not currently permissible under existing member state licences, which were built for terrestrial use. The Radio Spectrum Policy Group has recommended that the European Commission mandate CEPT to develop harmonised technical conditions, but progress is tied to WRC-27’s Agenda Item 1.13, which will set the global framework for satellite-to-handset services in bands between 694 MHz and 2.7 GHz.

Until that process concludes, EU operators cannot move at the speed the UK has. Cross-border roaming, interference management, emergency service obligations, and lawful intercept all require consistent handling across borders before D2D becomes a pan-European mass-market feature.

The UK is therefore running a live experiment that the rest of Europe cannot yet replicate, and the next 12 months of data, covering spring and summer outdoor usage seasons and the arrival of VodafoneThree’s competing service, will be closely watched by regulators and operators well beyond these shores.
