Tenby, one of Wales' most popular seaside towns, is facing significant frustration from both locals and tourists due to a lack of mobile phone signal. The Pembrokeshire town's postcode was named by consumer group Which? as the worst in the UK for mobile connectivity, according to a survey of over 4,000 members.
The survey, conducted in 2025, found that Tenby had the highest proportion of respondents reporting a 'very poor' or 'no signal' experience. This has impacted local businesses, with some reporting lost revenue due to customers being unable to make contact or use mobile payment systems.
Residents have expressed concerns about safety, particularly in emergencies, as the lack of signal can delay calls to emergency services. The issue is exacerbated during peak tourist seasons when the town's population swells.
Mobile network operators have acknowledged the problem, with some citing the town's geography and historic buildings as challenges. Plans for improved infrastructure, including new masts, have been proposed but progress has been slow.
