My FaceTime calls are connected to my wife’s phone

Hello Brswab2009,

Thank you for reaching out in Apple Support Communities. Are you and your wife sharing the same Apple ID account on each of your devices? If so, then this can cause FaceTime calls to appear on both devices. Here is additional details of why you'll want to avoid sharing the same Apple ID:

Avoid sharing an Apple ID

Apple recommends that you do not share your Apple ID. Instead, set up Family Sharing so that each person uses their own Apple ID. This way, your family can share purchases, subscriptions, and more without sharing personal information like email, text messages, or passwords.

If you share your Apple ID with a family member, certain services will treat you as the same person. You might see these issues:

* Apple Music family subscription: Instead of receiving your own membership with your own library, you’ll share a library and recommendations with the other family member.

* App Store, Apple Books, and iTunes purchases: If Family Sharing is ever stopped, the owner of the shared Apple ID will keep all purchases. You might lose access to everything in the account, including purchases you initiated.

* Apple Podcasts, Apple Books: Podcast episodes and bookmarks might sync according to the other family member’s preferences or be accidentally deleted.

* Messages: You might receive text messages that are intended for your family member.

* Fitness: You might see Health details, Workouts, and Fitness+ recommendations intended for your family member.

This information is outlined here: Make sure that each family member has a unique Apple ID - Apple Support

To prevent this from happening, you'll want to make sure to have your own Apple ID account. Here are the steps on how to create an Apple ID: How to create a new Apple ID - Apple Support
