Can someone help me?! I've just had a pop up notification saying a phone number that's not mine is using my Apple ID/iMessage. I've gone to my settings and my actual number is greyed out. It isn't a new phone/SIM card. How do I fix it and remove the telephone number that's not mine?
iPhone 6, iOS 9.2
Hi melzduff,
Welcome to the Apple Support Communities! I'm sorry to hear you are having these issues with Messages. I'm a bit unclear on the exact alert message you saw, but if it appears that an incorrect or unknown phone number is using your iMessage account, you may want to double-check that your iPhone's phone number is correctly linked with your Apple ID, as outlined in the following article:

I had the same issue, my iMessage is already tied to my phone number. But today a secondary number popped up wanted to be added to my iMessage and FaceTime. How does this happen?
