The UK mobile market has changed more in the last eighteen months than in the decade before it. There are now three mobile network operators instead of four, and the first satellite services are reaching ordinary smartphones. For any business that depends on mobile, both shifts bring risk and opportunity.
Four networks become three
The merger of Vodafone and Three completed in 2025, creating VodafoneThree with around 27 million mobile customers, alongside EE and Virgin Media O2. To secure approval, the Competition and Markets Authority required a joint network plan and commitments that include £11bn of investment over ten years, caps on selected tariffs for three years, and pre-set wholesale terms for virtual operators.
The opportunity
- Better networks. Significant investment in 5G coverage and capacity should improve service for business users over time.
- A moment to renegotiate. Integration brings new tariffs, new plans and competitive pressure between three larger players.
The risk
- Fewer choices. With one fewer operator, buyers have less leverage, and the price protections are time-limited.
- Change on the ground. Integrating two networks takes years. Migrations and changes to coverage can affect business users along the way.
- Single-network dependence. Many organisations rely on one operator for every handset. Consolidation makes that concentration more significant.
Mobile reaches for the sky
In February 2026, Virgin Media O2 launched O2 Satellite with SpaceX’s Starlink, connecting standard smartphones directly to satellites in areas with no mast coverage. In April 2026, Ofcom approved VodafoneThree to offer a similar service with AST SpaceMobile, with customer trials planned from this summer.
The opportunity
- Coverage where it was missing. Field teams, engineers and rural sites can stay reachable in places that have never had a signal.
- A new layer of resilience. Satellite offers a fallback when terrestrial networks fail, supporting lone-worker safety and business continuity.
- Connected assets. Remote equipment and sensors can report from locations that were previously out of reach.
The risk
- Early days. Today’s services are limited in speed and features, and depend on compatible handsets and tariffs.
- Not a replacement. Satellite complements terrestrial networks. It does not yet replace a proper resilience plan.
- Governance. Regulated firms must consider how messages sent over new channels are captured and retained, just as with any other business communication.
What leaders should do now
- Review contracts and renewal dates against the new market, before the price protections expire.
- Map where your people and assets lose signal, and decide where satellite could make a difference.
- Design for resilience rather than relying on one network for everything.
- Keep communications compliant, so new channels are covered by your capture and retention policies.
