FTC – How To Avoid, Spot, and Report Tech Support Scams

"Real security warnings and messages will never ask you to call a phone number."

If you have any doubts as to whether Apple wants to speak with you, look up Apple's official contact information – for yourself – on their Web site. Then contact them. Never trust a phone number or a link that you receive in some "security warning" that pops up out of the blue. Any scammer can put together a pack of lies claiming that they are from "Apple Security" or "Apple Support" or some such, and giving you a number to connect you to their call center for a fleecing.

It's a scam, ignore it. Apple will never send texts advising of purchases like that.

Scam.
