“SMS is engaging to the federal government as a result of it is a lowest frequent denominator messaging answer – it might probably reach lots of the most weak individuals in society who solely have a primary characteristic telephone.
“But it is probably not match for function as a result of the texts should be despatched out sequentially, that means individuals get them at completely different occasions.
“What we really need is a wireless emergency system like they have in the US, which would allow the government to get the same message to everyone at once – not just for coronavirus, but for things like major weather disruption, that pose a danger to life.”
One advantage of such a system is that the messages may be geographically focused, that means they are often restricted to a selected zone in a metropolis to – for instance – assist discover a lacking baby.
