If you blocked a number by mistake, or if you repaired a relationship with someone who you blocked, you can unblock that number or contact and start receiving calls, texts, and FaceTime invitations from them once again.
How Do I Unblock A Number?
- Open the Settings app on your iPhone.
- Scroll down and tap Phone.
- Tap Blocked and you'll see a list of blocked numbers and contacts appear on the screen.
- Swipe right to left on the contact you wish to take off your list of blocked callers, then tap Unblock when the option appears.
