It also states that, as you might expect, rural Scotland and Wales have the UK’s worst coverage and that just 67% of the UK has complete 4G coverage from the big four networks. Only 23% of English constituencies have complete 4G.

This is at odds with the mobile industry’s much-hyped recent jump to 5G, a network technology that promises better speeds and bandwidth in comparison to 4G. But as Which? Director of Advocacy Caroline Normand says, ““Millions of people are finding it difficult to get a reliable mobile connection and risk missing out on digital services we increasingly rely on like online banking, maps and NHS information – while some even struggle to receive important calls and messages.”

The latter comment points to the 8% of the country that has no 4G coverage at all, though those unlucky few should still manage to pick up a 2G cellular network for basic calls and SMS services.

A separate Which? survey found that a huge 49% of people asked said they get patchy mobile signal at least once a month. Alex Tofts at Broadband Genie addressed this issue by commenting, “Smartphone customers frustrated by the lack of signal can vote with their wallets by switching to a network which can provide service. If one 4G provider is not available in your area, chances are another will be. All the major providers have coverage information or a checker on their website, or you can use the OpenSignal mobile app to view crowd-sourced coverage data.”

It shows that while many people in major cities and towns enjoy blisteringly fast 4G for streaming music and video, a substantial number of the UK population is still underserved by the UK’s mobile networks.
