Apple texted me stating there was a problem with my ID and had to change it. I don’t know why. Is my ID ply?

Apple doesn’t text folks with that, and you’ve probably logged in here using that same Apple ID so it works, which would mean this would seem to be phishing; somebody trying to acquire your Apple ID credentials.

My first inclination is to think it may be phishing.

Scams (e-mail, text messages, and phone calls) are getting very good at closely imitating true Apple communications. Always be cautious. Here are some guidelines:

If you are uncertain about a message and a resource provided in that message, do not click on any links in the message. Try to independently verify the resource by going to a support page on apple.com and use that to contact Apple or to use the service the message is telling you to use.
