Major mobile network improvements are set to eliminate dead zones on key UK motorways, making navigation, EV charging, and in-car connectivity more reliable. Virgin Media O2 has announced upgrades across 590 miles of roads, including the M1, M4, M6, and M8, with further expansion planned for the M20, A14, and A75.
The Problem of Patchy Coverage
For years, drivers in the UK have faced inconsistent mobile signal on major routes. Even in 2025, approximately two percent of A and B roads still lack 4G coverage. The lack of reliable signal affects crucial services like sat-nav apps (Apple CarPlay, Android Auto) and EV charging, where many charge points require app-based payments or offer better rates through mobile apps.
How the Improvements Were Made
Virgin O2 identified weak coverage areas through real-world testing. Teams drove across the UK to pinpoint problem spots and prioritize upgrades. The result is optimized 4G and 5G coverage on key routes, backed by a £700 million investment in the company’s Mobile Transformation Plan.
EV Drivers’ Concerns
The move addresses rising concerns among EV drivers. A Virgin O2 survey found that 76 percent worry about mobile connectivity when driving, as reliable signal is essential for using chargepoint apps and accessing the best charging rates.
Strategic Synergy
The mobile upgrade aligns with Liberty Global’s broader investment in EV infrastructure. Virgin Media O2’s parent company also owns Believ, a chargepoint operator installing 30,000 new chargers in the same locations where mobile coverage is being improved. This coordinated approach ensures drivers have both reliable connectivity and accessible charging options.
“Connectivity underpins a huge part of the driving experience today, but particularly for EVs,” said Jeanie York, Virgin Media O2’s chief technology officer. “By optimizing coverage…we’re helping make every journey safer and more reliable.”
The upgrades mark a significant step towards modernizing the UK’s motorway network, enhancing safety, convenience, and accessibility for all drivers, especially as electric vehicle adoption continues to rise.
