Direct-to-Device Satellite Mobile in the UK: What Ofcom’s VodafoneThree Approval Tells Operators About the NTN Authorisation Path
In short: Ofcom approved a second licence variation on 15 April 2026 allowing VodafoneThree to deliver direct-to-device satellite services over its 900 MHz mobile spectrum using AST SpaceMobile. It is the second UK non-terrestrial network authorisation after Virgin Media O2 in 1800 MHz. Consultation on the paired handset exemption Regulations closes 18 May 2026.
Ofcom’s approval on 15 April 2026 of VodafoneThree’s second direct-to-device satellite licence variation takes the United Kingdom from a framework-in-principle to a working authorisation path. The decision covers VodafoneThree’s 900 MHz mobile spectrum, paired with AST SpaceMobile’s BlueBird low earth orbit constellation. It is the second non-terrestrial network clearance under Ofcom’s framework, following Virgin Media O2’s 1800 MHz Regulations made on 16 February 2026. Ofcom’s companion consultation on the amended handset exemption Regulations is open to 5pm on 18 May 2026.
The direct-to-device satellite authorisation mechanism Ofcom has settled on
Ofcom set out the regulatory design in its December 2025 Statement and gave it operational form in the 17 February 2026 Statement on the first Regulations. The Statements are summarised in our earlier analysis, Satellite Direct to Device: Ofcom Opens Mobile Spectrum to Space, which sets out the framework mechanics and the power-flux density and coordination conditions in more detail.
The authorisation is a two-limb instrument. The first limb is a variation to the mobile network operator’s existing Wireless Telegraphy Act 2006 licence, issued under section 8(1) of the Wireless Telegraphy Act 2006, permitting ground-to-space and space-to-ground transmission inside the operator’s licensed band. The second limb is a set of Regulations made under section 8(3) and consulted on under section 122(4), exempting user handsets from individual licensing when receiving the satellite signal. Without the exemption every user device would require a separate licence: the Regulations are what make the consumer product workable.
Electronic communications network and service obligations under the Communications Act 2003 Part 2 general authorisation apply by operation of law to the terrestrial operator offering the service. The General Conditions, including emergency call handling under GC A3 and information provision to consumers under GC C1, bind the MNO regardless of whether the underlying radio path is terrestrial or satellite. Ofcom has not created a separate consumer regulatory track for non-terrestrial delivery. The framework treats it as terrestrial mobile with an additional radio path.
How the VodafoneThree approval differs from Virgin Media O2
The two approvals share the same legal architecture. Each uses a licence variation under existing sub-3 GHz mobile holdings, paired with handset exemption Regulations made under WTA 2006 section 8(3). Each carries power-flux density and coordination conditions designed to protect adjacent terrestrial use. Each leaves GC obligations on the MNO intact.
They differ on four material points. Band: VodafoneThree uses 900 MHz, Virgin Media O2 uses 1800 MHz. Satellite partner and architecture: VodafoneThree has contracted with AST SpaceMobile, whose BlueBird satellites carry large unfolding phased-array antennas designed to close the link to unmodified handsets at sub-1 GHz; Virgin Media O2 uses SpaceX’s Starlink Direct-to-Cell service, which operates a lower-altitude constellation with different in-flight beamforming characteristics. Regulations status: the 1800 MHz Regulations were made on 16 February 2026 and are in force; the 900 MHz amendment Regulations are consulted on to 18 May 2026 and are not yet made. Coordination load: lower bands carry stronger propagation and higher interference cost per bit, which drives tighter PFD conditions on the 900 MHz variation than on the 1800 MHz instrument.

What operators should read into the second approval
The second authorisation confirms what the first suggested: Ofcom will approve NTN variations where the applicant is an existing terrestrial licensee in the relevant band, the partner satellite operator is willing to accept PFD and coordination conditions, and the MNO retains consumer-facing accountability. The question for an MNO considering a D2D launch is no longer whether the path exists. It is which band to use and on what commercial terms.
Band selection drives most of the commercial decision. Low band (700 MHz, 800 MHz, 900 MHz) carries further into buildings, handles foliage and weather better and is the only band where handsets already installed in the field will acquire the satellite signal without modification. The cost is coordination: lower bands have tighter PFD limits and more adjacent-use interference. Mid band (1800 MHz, 2100 MHz) offers greater capacity and lower coordination load but more limited physical penetration. 2.6 GHz is available in principle but carries the radar protection conditions flagged in Ofcom’s December 2025 Statement. Operators running on 700 MHz and 800 MHz have a similar conversation to start with their prospective satellite partner.
Coverage obligations attached to existing sub-1 GHz awards interact with the authorisation. The 700 MHz coverage obligations, and the legacy 800 MHz obligations inherited from the 2013 auction, are defined by geography and speed thresholds. Satellite delivery can contribute to geographic reach but does not count against throughput obligations unless Ofcom so determines. Operators bidding NTN capacity into official coverage reporting should expect scrutiny.
Consumer duties do not change. GC C1 (information provision), GC C3 (sales and marketing practices) and GC C5 (switching) apply in the ordinary way to a D2D service offered by an MNO. A proposition described as “always connected” carries the same advertising regulation risk as any other coverage claim. GC A3 (emergency calls) requires that 999 and 112 routing, caller location and priority handling work over the satellite path. Operators should expect Ofcom to ask for assurance that emergency call handling has been tested over the satellite radio path, not just the terrestrial one. Handset availability is the third practical constraint. Even with the exemption Regulations in force, the service only works on devices whose modems support the band and AST SpaceMobile’s air interface. The operator’s product timetable is a function of OEM firmware rollout, not only regulatory approval.
We advise MNOs and satellite operators on the authorisation path, coverage-obligation interactions, and consumer-facing terms. See Telecoms Product Launch Advice.
Investor implications
Two UK-specific investor theses follow from the second approval. First, the towerco thesis. D2D shifts the coverage-expansion cost curve: each kilometre of added reach no longer requires a tower. That is a negative for greenfield mast economics in rural gaps and a modest negative for tower rental growth, but it strengthens the case for dense urban towerco assets where D2D does not compete. Second, satellite operator exposure. UK MNO adoption gives AST SpaceMobile its first live, paying UK base and reinforces Starlink Direct-to-Cell’s. Lynk Global and Sateliot remain candidates for the next UK approvals. Private equity investors in European MNO assets should now price D2D as a commercial option, not a regulatory uncertainty.
Viewpoint
The second approval is important less for its own commercial terms than for what it establishes about the pattern. In December 2025 the question was whether the framework would deliver. On 16 February 2026 the question was whether Virgin Media O2 was a one-off. On 15 April 2026 the answer is clear: Ofcom will approve qualifying applications, and the gating questions are now commercial rather than regulatory. For operators the conversation has moved to band, partner, handset timing and contracting. For investors the discount for regulatory uncertainty should come out of the model.
