On the evening of Sunday, April 23 the UK government will be sounding the alarm by carrying out an emergency alert test on all 4G and 5G mobile networks.
Emergency Alerts is a UK government service designed to warn you if there’s a danger to life nearby, so that in an emergency, your mobile phone or tablet will receive an alert with advice about how to remain safe.
Phone users are being warned that using mobile phones during the 'Armageddon' alert could cause huge disruptions if you're shopping, banking or using popular mobile apps such as Whatsapp.
