Hacked or not?

Subject: Urgent Help Needed: Unrecognized Phone Number Added to my Apple ID for iMessage and FaceTime

Hello everyone,

I'm reaching out to this forum today because I encountered a concerning situation with my Apple ID and I'm in need of some guidance. Here's what happened:

While using my phone, a message suddenly appeared on my screen, stating the following:

"Add +91 ***** for ¡Message and FaceTime? This phone number was associated with the Apple ID."

I want to clarify that I never added this particular number to my iMessage or FaceTime contacts, which raises some serious concerns.

My immediate thought is whether my mobile device or Apple ID has been compromised by unauthorized access. I'm quite puzzled as to how someone could add a number to my Apple ID without my knowledge, and now I find myself unable to remove it. This situation has left me feeling uneasy, and I'm unsure about the appropriate steps to take.

Given the expertise and helpfulness of this community, I was hoping someone could shed some light on the situation and provide guidance on what I can do to resolve this issue. Has anyone experienced a similar situation before? If so, I would greatly appreciate any advice or recommendations you can offer.

Here are a few specific questions I have:

1. How can I determine whether my mobile device or Apple ID has indeed been hacked or compromised?

2. Is there a way to remove the unauthorized phone number from my Apple ID?

3. What additional security measures can I implement to prevent future incidents of this nature?

4. Should I contact Apple Support directly, or are there any steps I can take on my own before reaching out to them?

I understand that the situation may be complex, but any assistance or insights you can provide would be incredibly valuable to me. I rely heavily on my Apple ID for various purposes, and I want to ensure that my personal information remains secure.

Thank you all in advance for your time and support. I'm grateful to be a part of this forum, and I'm confident that with your collective knowledge, we can work towards a resolution.
