Network’s users report en masse that SMS, accompanied by piercing 10-second tone, never arrived
The mobile network Three said it was investigating why many of its users failed to receive an emergency alert from the government, the first nationwide test for the UK’s new national warning system.
The alarm was scheduled to sound at 3pm on all mobile devices connected to the UK’s 4G and 5G networks, but while the piercing, 10-second tone did arrive for millions of people, and up to a minute early for some, Three users reported en masse that they did not receive it.
