VodafoneThree has strengthened its partnership with CityFibre as part of its ambitious plan to expand 5G Standalone (5G SA) coverage across the United Kingdom.

Under the new agreement, CityFibre will provide network transmission services for selected VodafoneThree mobile sites, helping the telecom giant deliver faster, more reliable, and future-ready 5G connectivity nationwide.

The deal builds on a long-standing relationship between the two companies. CityFibre already supports VodafoneThree’s broadband services through its extensive full-fibre infrastructure, which currently covers millions of homes and businesses across the UK.

Supporting the Next Generation of 5G

The partnership plays a key role in VodafoneThree’s wider £11 billion network investment strategy, aimed at delivering 99% population coverage with 5G Standalone technology by 2030.

Unlike traditional 5G networks that still rely partly on older 4G infrastructure, 5G Standalone is built entirely on next-generation architecture. This allows for lower latency, higher network efficiency, improved reliability, and better support for technologies such as AI, IoT, smart cities, autonomous vehicles, and industrial automation.

VodafoneThree plans to increase its current 5G SA coverage significantly over the next few years, bringing faster mobile experiences to tens of millions of users.

CityFibre’s Growing Full-Fibre Network

CityFibre recently announced that its full-fibre network now passes nearly five million premises across the UK. The company aims to expand that figure to more than eight million premises in the coming years.

Its infrastructure already powers broadband services from major providers including Vodafone, Sky, and TalkTalk.

More than 330,000 Vodafone broadband customers currently use CityFibre’s network, including access to Vodafone’s high-speed 2.2 Gbps symmetrical broadband service, powered by advanced XGS-PON fibre technology.

Building a Future-Ready Telecom Network

VodafoneThree says the expanded partnership will help support both its mobile and broadband growth plans.

The company has already worked with Ericsson and Nokia on major network upgrades and has deployed Multi Operator Core Network (MOCN) technology, allowing customers to automatically connect to the strongest available signal across the combined Vodafone and Three networks.

The operator also reports that recent upgrades have reduced thousands of square kilometers of mobile coverage gaps while improving access to high-speed 5G services.

Why This Matters

As demand for cloud services, AI applications, streaming, gaming, and connected devices continues to grow, telecom operators are investing heavily in fibre and advanced wireless infrastructure.

The VodafoneThree-CityFibre agreement highlights how fibre broadband and 5G networks are increasingly working together to create the digital foundation needed for next-generation services.

Industry analysts believe that widespread deployment of 5G Standalone networks will be critical for supporting future innovations in artificial intelligence, edge computing, smart manufacturing, and connected transportation systems.
