How VodafoneThree Connects 50 Million Customers to Faster 5G

Britain’s mobile networks are under growing pressure as operators race to keep up with demand.

To the packed commuter trains, crowded stations and the constant stream of video calls straining networks, VodafoneThree believes it has found an answer.

The newly merged operator says it has completed what it describes as a world-first national network upgrade, integrating core and radio sharing technology across a multi-vendor 4G and 5G environment while also unlocking shared spectrum access for millions of users.

The result has been immediate and highly visible for customers.

VodafoneThree says up to 28.6 million Vodafone and Three subscribers are now automatically connecting to the strongest available signal across the combined network, helping remove 16,500km² of mobile not spots while improving speeds, reliability and capacity.

At the same time, roughly 71% of the UK population (50 million people) can now access the operator’s fastest 5G services through expanded use of shared C-band spectrum.

For the UK telco sector, the announcement marks one of the first major integration milestones following the Vodafone and Three merger and offers an early indication of how operators are increasingly using network orchestration and spectrum pooling to manage rising mobile traffic.

Building a shared national network

VodafoneThree has combined elements of both Vodafone and Three so customers can move dynamically between them depending on signal strength and congestion levels.

That means a customer connected to an overloaded site during rush hour can be shifted automatically to another nearby site with more available capacity.

According to the company, the process happens seamlessly without users needing to change settings or plans.

The operator says more than 10,000 sites across the UK have now been integrated as part of the programme.

Andrea Donà, Chief Network Officer at VodafoneThree, says: “This world-first network upgrade shows how VodafoneThree is using cutting-edge technology to transform the UK’s digital infrastructure.

“By unifying core and radio sharing at a national level, while also introducing intelligent orchestration and dynamic capacity management, we’re setting a new benchmark for network performance.”

The scale of the integration is significant because it combines both core network functions and radio access technologies across equipment supplied by multiple vendors.

Ericsson recently outlined the project in a whitepaper, describing it as the first deployment of its kind at national scale.

How C-Band is significant

Much of VodafoneThree’s 5G strategy centres on its C-band spectrum holdings between 3.4GHz and 3.8GHz.

The mid-band frequencies are viewed by operators as the sweet spot for 5G deployment because they balance wide-area coverage with the higher capacity needed for bandwidth-heavy applications.

For consumers, that translates into smoother streaming, more stable video calls and faster mobile gaming. For enterprise customers, the spectrum supports services requiring lower latency and higher throughput, including IoT deployments, connected devices and real-time monitoring applications.

VodafoneThree says it now holds more C-band spectrum than any other UK operator, allowing it to scale deployments more aggressively across towns, cities and business hubs.

The operator has also targeted high-footfall locations including stadiums, airports and event venues where temporary demand spikes often strain mobile infrastructure.

£11bn Integration Push

The network upgrade forms part of VodafoneThree’s wider £11bn (US$14.7bn) investment programme, which aims to expand and modernise infrastructure across the UK over the next decade.

In September 2025, the operator selected Ericsson as a strategic build partner to help deploy next-generation radio access and core network technologies nationwide.

VodafoneThree says the long-term objective is to provide 5G Standalone coverage to 99% of the UK population by 2030 before extending that figure to 99.96% by 2034.

Alongside faster speeds, the operator is positioning the investment as a resilience and coverage programme designed to strengthen connectivity in areas that have historically struggled with patchy service.

Andrea says: “This upgrade means customers are already experiencing improved reliability and coverage, as well as access to our fastest 5G speeds today.

“But this is just the beginning. As we continue rolling out upgrades through our £11 billion investment, customers can expect even better performance, with even faster speeds.”
