The message will be received on 4G and 5G mobile phones, along with sound and vibration for up to 10 seconds.
Phone users will be prompted to acknowledge the alert by swiping or clicking the message before being able to continue using their device. Officials said they have worked with the Football Association and the Marathon’s organisers to make sure the impact of the test will be limited.chairman Mark Hardingham said: “For 10 seconds the national test may be inconvenient for some, but please forgive us for the intrusion because, the next time you hear, it your life, and the life-saving actions of our emergency services, could depend on it.
