Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what steps her Department is taking to improve 4G and 5G mobile connectivity on major motorway routes in areas where there are known signal black spots.

According to Ofcom’s Connected Nations Spring update, published on 8 May 2025, 4G in-vehicle coverage on UK major roads is 96% from at least one mobile network operator (MNO) and 81% from all four MNOs.

The Shared Rural Network has improved 4G mobile coverage along 16,000km of roads. The 10 Year Infrastructure Strategy (June 2025) committed to work with Ofcom and other regulators to assess the telecommunications needs of the transport sector, including the future requirements of roads, by December 2026. My officials are undertaking this assessment alongside the Department for Transport and the National Infrastructure and Service Transformation Authority.
