I have received a text message saying that I've been in a venue where there has been an outbreak of covid. The message doesn't say when it was or where the venue is. Other than one visit to the supermarket, I haven't been anywhere though.
I'm confident that the message is legit as it has come from the same sender as when I booked a pcr test in the past.
But where did they get my number from? I have the app but contact tracing is switched off. Would somebody have had to give my phone number as part of track and trace?
