We were forewarned that our mobile phones would signal a buzz and display a message at 3PM BST yesterday.
It went off a minute early.
Going in, they claimed that this emergency messaging thing would be used to warn people about potential dangers within the users' vicinity. For example, in the case of flooding.
I personally think it is being done for a more serious reason like if the country finds itself in another war. A modern-day air raid siren, if you will.
This is not something new. Many countries have been doing these phones for years.
