O2 launched its next-generation 5G standalone network across Wales in May 2026, bringing faster and more reliable mobile broadband to more than 800,000 homes and businesses. For the many Welsh households still waiting for full-fibre broadband, 5G offers a faster alternative - available the next day, with no engineer visit needed.
5G in Wales got a major boost in May 2026 as O2 launched its next-generation 5G standalone network across the country. That's welcome news for hundreds of thousands of Welsh households - particularly those in areas where traditional wired broadband providers have been slow to install full-fibre.
Mobile broadband provides a practical solution for anyone tired of waiting for fibre to reach their street. Here's what the O2 rollout means for homes across Wales.
O2 rolls out standalone 5G in Wales
O2 confirmed in May 2026 that its 5G+ (Standalone 5G) service is now available across Wales. More than 800,000 homes and businesses can now connect to a dedicated next-generation network, with improved download and upload speeds and better reliability than standard 5G.
The areas covered include Welsh capital Cardiff, Newport, 26 other towns and cities, and more than 100 villages. O2 only launches its 5G+ service in areas with more than 90% outdoor 5G coverage, so customers in covered locations can expect consistently strong signal.
800,000+ homes and businesses across Wales can now access O2's 5G+ standalone network - covering Cardiff, 26 towns and cities, and more than 100 villages, with a minimum of 90% outdoor coverage in each area.
Virgin Media O2 customers in these areas can take advantage of average speeds of 150-200 Mbps through a dedicated 5G mobile broadband router - in both rural and urban locations.
Wales lags behind in traditional broadband rollout
While the availability of fibre broadband in Wales has improved in recent years, it still trails behind other UK nations. According to Ofcom's Connected Nations report, around 68% of homes in Wales have access to full-fibre broadband - compared to more than 93% in Northern Ireland.
Traditional broadband availability also varies widely across Welsh constituencies. In some of the most rural areas, coverage gaps are significant.
In Rhondda and Ogmore, just 36% of households have access to full-fibre broadband. In Brecon, Radnor and Cwm Tawe, the figure is 41% - leaving thousands of households dependent on slower connections, according to Ofcom's December 2024 Connected Nations report.
The gap matters because ultrafast full-fibre broadband requires physical cabling running to every property. The rollout is slow and costly, and there's limited commercial incentive for mainstream providers to extend coverage to isolated or rural homes.
How 5G could help more Welsh homes get fast broadband - faster
5G in Wales offers a practical alternative for the thousands of households still waiting for fibre. Unlike full-fibre broadband, 5G mobile broadband only needs a strong mobile signal broadcast from a nearby mast. Once 5G coverage is available at your address, getting connected is straightforward.
A 5G mobile broadband router can be delivered and set up in minutes - no engineer visit, no long installation wait. Most customers are online the same or next day.
For rural Welsh households that have waited years for a fibre connection, 5G mobile broadband is increasingly the fastest route to superfast speeds - not a stopgap, but a genuine long-term solution.

What you need to know
What is 5G standalone (5GSA)?
5G standalone - also called 5G+ by O2 - is a next-generation mobile network that runs entirely on 5G infrastructure, rather than using older 4G technology as a backbone. This gives it faster speeds, lower latency and more reliable performance than standard 5G, especially in busy areas or at peak times.
Which areas of Wales now have O2 5G+?
As of May 2026, O2's 5G+ network covers Cardiff, Newport, and more than 26 other towns and cities across Wales, as well as more than 100 villages. Coverage extends to more than 800,000 homes and businesses. O2 only launches in areas with at least 90% outdoor 5G+ coverage.
Can I get 5G broadband if I can't get fibre in Wales?
Yes. 5G mobile broadband is available wherever there's a strong 5G signal, regardless of whether fibre cables have been installed in your area. It's an increasingly popular alternative for rural Welsh households, with speeds of 150-200 Mbps available through a home broadband router.
How fast is 5G mobile broadband?
Typical speeds on O2's 5G+ network in Wales are 150-200 Mbps for home broadband connections. That's fast enough for 4K streaming, video calls, online gaming and working from home simultaneously across multiple devices.
How quickly can I get 5G broadband set up?
Unlike full-fibre broadband, 5G home broadband requires no engineer visit or installation. A mobile broadband router is delivered to your door, and most customers are online within minutes of it arriving - often the same or next working day after ordering.
What is Connectivity's multi-network broadband?
Connectivity's multi-network plans give you access to whichever mobile network has the strongest signal at your address - including O2's 5G+ network. If coverage improves or changes in your area, you can switch networks without changing provider.
