Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, whether any assessment has been made of the number of mobile phones where the users have turned off government and emergency alerts in their phone settings.

Emergency Alerts operate on cell broadcast technology, which does not require or gather any information from individual handsets. Therefore, it is not possible to validate which handsets have opted out in their phone settings.

Emergency alerts contain life-saving information and should be kept switched on for safety. However, individuals can opt out. For example, victims of domestic abuse with concealed phones may find it appropriate to opt out of receiving Emergency Alerts. Information on opting out can be found at https://www.gov.uk/alerts.
