Key Takeaways
- Tenby, a popular Welsh seaside town, has been identified as the UK’s worst location for mobile phone signal, with a “good” connection only 54.3 % of the time.
- The poor coverage stems largely from the decommissioning of a local mast in early 2026, affecting O₂, Vodafone and Three customers.
- Local businesses report lost sales and operational delays because card payments frequently fail, forcing many to rely on cash.
- Tourists experience frustration, including difficulty contacting services, checking weather, and arranging transport, which may deter repeat visits.
- Network operators acknowledge the issue, cite mast replacement work, and mention temporary measures and infrastructure optimisations to improve coverage.
- Other poorly performing postcodes include Llandrindod Wells, parts of Somerset, Cornwall, Worcestershire and Carmarthen, while the best signals are concentrated in southeast London and Nottingham.
Overview of Tenby’s Tourist Appeal
Tenby is renowned across the United Kingdom for its picturesque seafront, historic harbour, and vibrant mix of traditional pubs, acclaimed eateries, and scenic beaches. Each summer, tens of thousands of visitors flock to the Pembrokeshire town to enjoy its sandy shores, coastal walks, and cultural festivals. The town’s charm lies in its ability to blend centuries‑old architecture with modern amenities, making it a favoured destination for families, couples, and solo travellers alike. Despite its allure, a growing concern has begun to overshadow the visitor experience: unreliable mobile phone connectivity.
Mobile Coverage Rankings and Statistics
According to the consumer advocacy group Which?, Tenby’s postcode SA70 recorded the lowest mobile network quality in the UK for 2025, with users experiencing a “good” signal just 54.3 % of the time on average. This figure places Tenby at the bottom of the national rankings, narrowly outperformed only by Llandrindod Wells (LD1) at 54.8 %. Carmarthen (SA31) follows as the sixth‑worst area, while the remaining spots in the top ten are all located in England. In stark contrast, the best‑performing postcodes—such as SE11 in Kennington, London, and NG3 in Nottingham—enjoy reliable coverage exceeding 90 % of the time. The disparity underscores a significant regional divide in telecommunications infrastructure.
Impact on Local Businesses
Local traders and service providers describe the poor signal as a direct threat to their livelihoods. Steven Roberts, a taxi driver who has worked in Tenby for three years, explained that the intermittent connection often forces him to keep his phone pressed against a door or window just to maintain a rudimentary link. “You can be there for 10 minutes trying to get a signal and then that delays you for your next call,” he said, noting that failed card payments have led him to advertise his services as cash‑only on social media. Guy Manning, proprietor of an art shop, echoed these sentiments, stating that the inability to process card transactions has definitely cost him customers, particularly tourists who prefer not to carry cash and may opt to visit competitors with better connectivity.
Tourist Experience and Frustrations
Visitors echo the frustrations of residents, citing the signal loss as a hindrance to everyday conveniences. Paul Wiston, a self‑employed traveller from Cheshire, described the difficulty of staying in touch with clients and even checking the weather forecast while in Tenby. “I can’t even get the weather forecast up — it’s frustrating. I mean it’s a lovely place but just terrible signal. We walked home last night because we couldn’t call a taxi,” he recounted. The inability to summon transport, access online maps, or share holiday moments in real time diminishes the overall enjoyment of the stay and may influence decisions about returning to the town in future seasons.
Statements from Mobile Network Operators
In response to the criticism, O₂ acknowledged the signal issues, attributing them to the decommissioning of a local mast and confirming that its infrastructure partner, Vodafone, is working to locate and install a replacement as quickly as possible. Vodafone and Three issued a joint apology to affected customers, stating they are collaborating with their infrastructure partner on a longer‑term solution while exploring temporary options to restore coverage. EE, which does not own the removed mast, said it is actively assessing ways to enhance connectivity in Tenby and the surrounding area, including upgrading an existing mast site in nearby Penally. Collectively, the operators emphasize their commitment to minimizing disruption, though concrete timelines for full restoration remain unspecified.
Broader Context: UK Mobile Coverage Rankings
Tenby’s predicament fits within a wider pattern of uneven mobile coverage across the United Kingdom. The Which? list of the ten worst‑performing postcodes includes locations such as TA5 (north‑west Somerset), TR4 (Cornwall near Truro), DY13 (parts of Worcestershire), and several Cornish towns like TR27 (Hayle) and TR18 (Penzance). Notably, the best‑performing areas are largely confined to urban centres in southeast London and parts of Nottingham, highlighting a rural‑urban divide. This disparity raises questions about the economics of mast deployment, the challenges of providing reliable service in geographically complex coastal regions, and the regulatory pressures on providers to meet universal service obligations.
Potential Solutions and Outlook
Addressing Tenby’s connectivity shortfall will likely require a multi‑faceted approach. Short‑term measures could involve deploying temporary mobile cells or signal boosters to bridge the gap while a permanent mast is constructed. Long‑term solutions may include sharing infrastructure among operators to reduce duplication, investing in newer technologies such as 5G small cells that are better suited to varied topography, and encouraging local authorities to facilitate mast planning processes. Stakeholders—including businesses, residents, and tourists—have voiced a clear demand for reliable service, arguing that the cost of mobile contracts should be matched by consistent network performance. Whether the promised upgrades will arrive before the next peak tourist season remains to be seen, but the issue has undoubtedly placed Tenby at the forefront of the national conversation on mobile equity.
