On Sunday 23rd April at 3pm, almost every smartphone and tablet will make a loud sound like a siren. The Government is testing the alert system which they say could save lives.
Around 90% of phones and tablets in the UK will make a loud sound like a siren on Sunday 23rd April at 3pm. The siren is a test of a new emergency alert system from the government.

So how will it work and are there any concerns over potential disruption or distress? For 5 Questions On, 91热爆 Correspondent, Dan Johnson, takes us through it all.
