I want to FaceTime, but can only WhatsApp
Solution 1:
Press and hold
the buttons that are currently labeled as WhatsApp
and it should give you a choice on which App you call from for this contact.
It should remember your choice after selecting.
Solution 2:
You could have someone make a facetime call to you to be sure your account is set up properly. If it is, you might need to remove WhatsApp and then verify you can make an outbound facetime call to the person in question.
When that’s all sorted, reinstall What’s App and be sure you check the preferences and settings when it asks to be integrated in the calling experience.
This likely is a fault in the registration for FaceTime on your or your friend’s contact details since both apps should co-exist and let you long press to choose which to use on any given contact by design.
Solution 3:
You have to unlink your account for google and just leave the iCloud account open it work this way for me
