In Houston area, my wife heard another test of the Emergency Broadcast System early this morning.
She commented that this was the 3rd test of the EBS she's heard in the last 24-hours. She asked me how many tests do they need?
I mentioned that you only get ONE chance to re-take a country and save it from destruction... so you do as many tests as you need to get it right. If SHTF in a month or so, they want as few civilians in the way as possible.
The UK has never used the emergency broadcast system in the past; it was pretty much a US thing. I believe in the US the various types of broadcast can be optionally enabled, except for Presidential Alerts which are obligatory to receive. They moaned at Trump for that in fact.
Because we never used it, many UK phone firmwares covered it up by removing from settings. My phone has the global firmware because imported it myself from China.
Look in your phone settings to see if you can turn on alerts. More info at

Not having 'test & trace' is a good reason for not having a smartphone.
