Emergencies: Mobile Phones
The question
To ask the Minister for the Cabinet Office, with reference to the publication entitled UK Government Resilience Action Plan published on 8 July 2025, what steps his Department is taking to ensure the adequacy of emergency alert systems in rural areas with (a) poor and (b) no mobile signal.
Answered by Ms Abena Oppong-Asare
Emergency Alerts are broadcast through mobile phone masts, and will be received by phones connected to the targeted masts. 95% of the UK landmass has 4G/5G coverage.
The Department for Science, Innovation and Technology is continuing to work with the UK telecommunications industry to deliver 4G and 5G mobile connectivity to places where there is limited or no coverage.
Emergency alerts are part of a collection of warning and informing systems that we use in the UK for emergency response scenarios. Other methods include local sirens and knocking door-to-door when safe, as well as providing advice through media such as TV and radio.
