My phone number being used on a new iphone?

I just got a message saying "Your phone number is now being used for iMessage and FaceTime on a new iPhone. If you recently signed into 'The Wizard' you can ignore this notification." I'm the only person on this apple ID account and I don't know what The Wizard is. Does anyone know what this means or how it happened?

Could be pretty much anything. I would check it out (on a computer) if it gives any sort of website or contact info. But do not for now click on anything in the message with you phone.

Someone probably just hacked your Apple ID, and you should go to the Apple ID help center found on the website.

If you are the only person with that ID, then go change your password As soon as possible. Make it something that can't be guessed like have some numbers at the end or beginning for sure.
