Receiving unsolicited phone calls or text messages? Well, it’s possible to block them.
Open the Phone app and tap Recents. Find the number you want to block and tap the ‘i‘ button next to the entry. From here scroll to the bottom and tap Block this Caller.
This will also stop them from messaging you or trying to start a FaceTime call.
If you change your mind or want to see the list of blocked callers, open the Settings app and select the Phone option. From here, tap Blocked Contacts 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.
