Why Monzo Mobile is Entering the UK's Telco Market

Monzo is moving beyond digital banking with the launch of Monzo Mobile, a new eSIM-based mobile service that will operate on Virgin Media O2’s network.

Set to launch this summer, the service marks the fintech’s first major expansion into the telco market and reflects a broader push by digital platforms to combine financial and connectivity services within a single app experience.

The move gives Monzo access to nationwide 5G infrastructure while offering customers mobile plans integrated directly into the banking app already used by 14 million personal customers in the UK.

Monzo is focusing on flexibility and visibility over telco spending, bringing mobile management into the same interface customers use for budgeting, payments and savings.

Virgin Media O2 powers Monzo’s network

The service is being launched through a multi-year exclusive partnership with Virgin Media O2, which will provide the underlying mobile network infrastructure.

The agreement strengthens Virgin Media O2’s position in the UK mobile virtual network operator market, where operators support brands looking to launch telco services without building their own infrastructure.

Paul O’Sullivan, Director of Wholesale Mobile at Virgin Media O2, says: “This partnership underlines the strength of the O2 network and our position as the UK’s trusted host of choice for MVNOs.

“Our unrivalled record helping partners launch and scale, alongside continued investment to upgrade and expand our mobile network, will enable us to support Monzo Mobile with ever-improving services.”

Virgin Media O2 is continuing a £700m (US$937.2m) investment programme into network upgrades this year, supporting demand for higher-capacity 5G services as digital-first brands seek to bundle connectivity with other consumer services.

For Monzo, the partnership offers a faster route into telecoms while avoiding the costs associated with deploying its own network infrastructure.

Building global roaming through 1GLOBAL

Alongside domestic coverage, Monzo has partnered with telco platform provider 1GLOBAL to deliver international roaming capabilities.

The partnership gives Monzo Mobile customers access to more than 600 networks across over 200 destinations, allowing roaming services to be managed directly through the Monzo app.

Hakan Koç, Founder and CEO of 1GLOBAL, says: “This partnership shows that mobile offerings can be key differentiators and growth drivers for digital businesses.

“At 1GLOBAL, we help digital champions like Monzo turbocharge their customer experience by embedding global connectivity directly into their service.

“Through our expansive international roaming infrastructure, Monzo customers can stay connected across more than 200 destinations – managed entirely within the Monzo app.”

The roaming partnership reflects growing demand for eSIM services that remove friction for frequent travellers, particularly customers who want to avoid switching providers or managing separate roaming products abroad.

By integrating international connectivity directly into its app, Monzo is aiming to position mobile services as another core utility alongside banking.

Flexible plans target digital-first users

Monzo Mobile will launch with three flexible plans, allowing customers to upgrade or cancel without long-term contracts or exit fees.

Users will also be able to monitor data usage, roaming costs and mobile spending from within the Monzo app itself.

The model mirrors wider changes across the telco market, where app-based operators and MVNOs are using digital account management and flexible billing as a competitive differentiator against traditional contract structures.

Duygu Yenidogan-Schmidt, General Manager of Core Banking at Monzo, says: "Monzo Mobile is a natural extension of our mission to make money work for everyone.

"By bringing mobile connectivity into the Monzo app through a simple eSIM experience, we’re giving customers more visibility and control over another essential part of their everyday spending.

"Partnering with 1GLOBAL and Virgin Media O2 allows us to deliver a reliable, flexible and high-quality service, while continuing to build products that are simple, transparent and designed around our customers’ needs."

The launch also highlights how telco infrastructure providers are enabling non-telco brands to offer connectivity services under their own identity.

For operators such as Virgin Media O2 and connectivity platforms like 1GLOBAL, partnerships with fintechs and digital consumer brands create new wholesale revenue opportunities while extending the reach of their networks into adjacent sectors.

Monzo’s move into mobile services suggests the boundary between fintech and telco is narrowing, as eSIM technology makes it easier for digital platforms to embed connectivity directly into existing customer experiences.
