Receiving unnecessary calls or text messages? Well, it’s possible to block them.
Open the FaceTime app and tap the i next to the unwanted caller. From here scroll to the bottom and tap Block this Caller.
If you change your mind or want to see the list of blocked callers, open the Settings app and select the FaceTime option. From here tap Blocked to see the full list. Now tap Edit in the top right followed by the minus icon, then Unblock. They’ll now be able to make contact once more.
