Unblock A Number

1. Open the Settings app on your iPhone.
2. Scroll down and tap Phone.
3. Tap Blocked and you’ll see a list of blocked numbers and contacts appear on the screen.
4. Swipe right to left on the contact you wish to take off your list of blocked callers, then tap Unblock when the option appears.

Why this works:

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.
