This is clearly someone pushing their luck
By chance, I received one of these texts earlier today completely out of the blue. I also had a missed call, I never answer calls on my punting phone unless I'm going on a meet.
It would appear that my number has obviously been saved by a WG/pimp/maid etc as I haven't messaged anyone on it in a couple of months. I have been in touch with two ladies in the last 3-4 weeks but this was through the AW messaging system and numbers were not exchanged as those didn't turn into meets.
I blocked and deleted the text I received today, it was a very amateurish scam IMO and it hasn't phased me in the slightest, its just annoying as I'll probably get spammed again. May have to change the number/sim when the monthly credit expires.
Like others have mentioned on here, there's no chance they've got your details apart from your number, and even if they did know where you lived they won't come knocking.
