Just received a text message from a mobile No, not one in my contacts.
'You have (1) missed message from Apple.
di bla. 199/uk'
Bit of research on web, and loads more are getting same, and a few have clicked on the link, only to be directed to a site, that looks like Apple's, but asking for details.
I actually sent a text back to the mobile number, but cannot repeat what I wrote on here.....
