You should block numbers on your iPhone if you constantly receive spam calls. However, sometimes, you may accidentally block the wrong person and will need to unblock them to start receiving calls and texts from them again. The following article will show you how to do it!
How to view and unblock blocked numbers on iPhone
When you block someone on iPhone, they can't call, text, or FaceTime you. Your iPhone will send the blocked contact directly to voicemail without notifying you of any missed calls or messages from them.
Your iPhone uses the same blocked list for phone calls, text messages, iMessage, and FaceTime. If you want to unblock someone, all you have to do is remove their number or contact information from this list. Here's how:
- Open the app Setting on iPhone.
- Enter Apps > Phone > Blocked Contacts to see all blocked contacts on your iPhone.
- Swipe left on a contact you want to unblock.
- Press Unblock to remove that person from your blocked list.

How to prevent iPhone from blocking unknown callers
Still missing phone calls or messages even though your “Blocked Contacts” list is empty? This can happen if the “Mute Unknown Calls” feature is active on your iPhone. When this feature is turned on, your iPhone will automatically mute calls from anyone who is not in your contact list.
To prevent iPhone from blocking unknown callers:
- Open the application Setting on iPhone.
- Enter Applications > Phone.
- Scroll down and tap options Mute unknown calls.
- Turn off the toggle button Mute unknown calls.

Tips: If you're worried about receiving spam calls, you can install an app like TrueCaller, which helps identify unknown callers and tells you when to pick up the phone.
Whether you want to unblock a specific contact or unblock all unknown callers on your iPhone, the process is quite simple. Additionally, there are ways to find out if someone has blocked your phone number if you can't reach them.
