Not necessarily.
I agree that these scams do pray on those who genuinely do have iffy things on their phones, bt they also rely on the fact that e.g. knowing the name and the email address of someone causes them to panic because they think that the scammer must know them/that they’re being watched.
My DP had one at work years ago which was similar, he ignored it, but work took it very seriously wrt why someone would contact him, even though it’s a well known scam.
I block and delete all manner of this crap
Although if you reply to the “hi mum I’ve lost my phone” text with something along the lines of “you’ll have to be more specific as to which child you are given I have more than one,” they block you 😂.
