Fintech MVNOs Push UK Mobile Market Toward 30% Virtual Share

UK mobile virtual network operators are on course to take more than 30% of non-machine mobile connections by 2031, Capacity Media covered, as fintech brands turn eSIM distribution into a new route into connectivity.

The forecast points to a retail-market shift rather than a network-build story.

MVNOs still depend on host operators for radio access, but their customer acquisition is moving into apps, loyalty ecosystems and embedded financial services that already have consumer attention.

Fintech Apps Become Mobile Storefronts

FDM CCS Insight's Spotlight: MVNOs, UK, 2026 forecast puts today's MVNO share at about 23% of the UK mobile market, excluding machine-to-machine connections.

By 2031, the group is expected to move above 30%, while service revenue almost doubles from just under £2.4bn in 2025 to more than £4.5bn.

Fintech entrants are the sharpest change in that mix.

Companies can offer connectivity from inside existing customer apps through eSIM activation, using enablement providers such as Gigs and 1Global rather than building a mobile retail stack from scratch.

That route lowers the friction of selling a second service to an existing user base.

A banking, payments or loyalty app can place mobile service beside cards, accounts or rewards, making connectivity part of a broader subscription or customer-retention package.

Host Operators Gain Wholesale Revenue

The operator impact is mixed.

Wholesale demand gives network owners another way to fill capacity and collect revenue from customers they may not acquire directly.

At the same time, stronger virtual brands create more retail competition for O2, EE, Three and Vodafone.

FDM CCS Insight consumer and connectivity director Kester Mann framed the trend as bittersweet for network operators.

New virtual providers can lift wholesale income, but their growth also threatens operators' direct subscriber bases, with losses only partly offset by sub-brands such as giffgaff and Voxi.

The forecast excludes those operator-owned sub-brands, so the projected MVNO expansion is not simply a relabelling of incumbent customers.

The forecast excludes operator sub-brands such as giffgaff and Voxi, keeping the measured expansion focused on independent and adjacent brands.

Scale Still Has A Ceiling

Fintech-led MVNOs are expected to reach more than 3 million UK customers by 2031, equal to roughly 11% of the MVNO market.

That would make financial-services brands a meaningful mobile channel even if their average revenue per user remains below that of network operators.

The growth curve may slow late in the decade.

Host operators still control network access, contract terms and wholesale economics, giving them leverage when virtual providers become large enough to affect retail pricing.

Established MVNOs will therefore need more than cheap tariffs.

Broader product bundles, home broadband, clearer brand positioning and tighter loyalty-programme integration could separate durable virtual operators from price-led challengers.

Control of the access layer remains the ceiling on that shift.

The sales interface can move into fintech apps, but network owners still set the wholesale terms that determine how far virtual brands can grow.
