What can I do to fix facetime not working on iPhone?

If you face the issue of why is my facetime not working on iphone, check that your internet connection is stable and FaceTime is enabled under Settings > FaceTime with your Apple ID signed in. Restart your phone, update to the latest iOS version, and ensure your date and time settings are correct. Sign out and back into FaceTime, reset network settings, and check if the person you're calling is blocked. You can also visit Apple’s System Status page to see if FaceTime is down. If the issue persists, contact Apple Support.
