Unable to make FaceTime calls from my iPhone

Re: "i just changed my phone to 15 Pro Max"

If you haven't already done so:

✽ You may want to first update your new iPhone to the newest IOS update:

Eg: About iOS 18 Updates - Apple Support says: iOS 18.3.2

"This update provides important bug fixes, security updates,

and addresses an issue that may prevent playback of some streaming content."

NB: It is always wise to back-up your data before updating iOS:

how can i solve this? it's frustrating"

Your Apple ID is the account you use to access Apple services, such as the App Store, Apple Music, iCloud, iMessage, FaceTime and more.

✽ Check you are signed in (to your iPhone) with you correct Apple ID and password you use for FaceTime:

See how to: Sign in to your Apple Account - Apple Support

✽ Check you have a "Contacts card" for yourself listed in the Contacts app:

Eg: Add or edit your contact info and photo on iPhone - Apple Support

✽ Check you have set-up FaceTime so you can be reached:

Get started with FaceTime on iPhone - Apple Support

Eg: says:

"To get started with FaceTime, go to Settings  > Apps > FaceTime, then sign in to your Apple Account or turn on FaceTime. If more than one contact method appears below “You can be reached by FaceTime at,” you can tap to select or deselect it."
