What blocking actually does on an iPhone

When you block someone on an iPhone, that person cannot call you, text you, or reach you through FaceTime. Their calls go straight to voicemail as if your phone is off. Their text messages and iMessages do not arrive at all. If they try to FaceTime you, they will see a message saying the call failed.

Blocking does not delete past conversations or hide you from social media. It only stops new contact attempts through the phone, Messages, and FaceTime apps. The blocked person can still see your public social media profiles, and old text threads stay in your Messages app — you just will not receive new ones from them.

One thing many people do not realize: if you block someone and then unblock them later, they do not get a notification that you blocked them in the first place. There is no alert sent to them when you block or unblock.

Key Takeaways

  • Blocking stops calls, texts, and FaceTime from reaching you, but does not delete past messages or hide you from social media.
  • You can block someone from the Phone app, Messages app, or by going to Settings and selecting the person's contact.
  • A blocked person will not receive a notification that you blocked them, and their calls will go to voicemail without ringing your phone.
  • You can unblock someone at any time through the same apps or through Settings, and there is no record left behind for them to see.

How to block someone from the Phone app

Open the Phone app and find the person's number in your recent calls list or contacts. Tap the information icon (a small circle with an "i" inside) next to their name or number. Scroll down and tap "Block this Caller." A confirmation message will appear — tap "Block Contact" to confirm.

If you want to block someone whose number is not in your recent calls, open Contacts, find their name, tap the information icon, scroll down, and tap "Block this Caller" the same way.

How to block someone from the Messages app

Open Messages and find the conversation with the person you want to block. Swipe left on their name (or long-press on it, depending on your iOS version). A menu will appear with options including "Block." Tap it, then confirm by tapping "Block Contact" in the popup.

Alternatively, open the conversation, tap the person's name or number at the top of the screen, then tap "Info." Scroll down and tap "Block this Caller."

How to block someone through Settings

Go to Settings, then scroll down and tap "Phone" (or "Messages" if you want to block them from texting specifically). Tap "Blocked Contacts" or "Blocked Messages" depending on which app you chose. Tap "Add New" or the plus sign, then search for and select the person you want to block.

This method is useful if you want to block someone before they have called or texted you, or if you want to block them across multiple apps at once.

How to block someone on FaceTime

Open FaceTime and find the person in your recent calls or contacts. Tap the information icon next to their name, scroll down, and tap "Block this Caller." You can also block them from the FaceTime app by swiping left on their name in your recents and tapping "Block."

Blocking someone on FaceTime does not automatically block them on Phone or Messages — you have to block them separately in each app if you want to stop all contact.

What happens after you block someone

Once blocked, that person's calls will go straight to voicemail. They will not hear a busy signal or any indication that you blocked them — it will sound like your phone is off or you are not available. Their text messages will not arrive, and if they try to send an iMessage, it will appear to send on their end but will never reach you.

If they try to FaceTime you, they will see a message saying the call failed. They may try again and get the same result, but they will not know for certain that you blocked them — they might assume you are just not answering.

You will still see their contact in your phone, and any old messages from them will remain in your Messages app. You can read old conversations whenever you want, but you will not receive new messages from them unless you unblock them.

How to unblock someone

To unblock someone, go to Settings, tap "Phone" (or "Messages"), then tap "Blocked Contacts" (or "Blocked Messages"). Find the person's name in the list, swipe left on it, and tap "Unblock." Confirm the action if prompted.

You can also unblock someone from within the Phone, Messages, or FaceTime apps by finding their contact, tapping the information icon, and looking for an "Unblock" option instead of "Block."

Once you unblock someone, they can call, text, and FaceTime you again. They will not be notified that you unblocked them, and there is no way for them to know you had blocked them in the first place.

Frequently Asked Questions

Can a blocked person see that I blocked them?

No. A blocked person will not receive any notification. Their calls go to voicemail and their texts do not arrive, but they have no way to know for certain that you blocked them rather than straightforward not answering.

If I block someone, can they still see my location or my profile picture?

Blocking only affects calls, texts, and FaceTime. It does not hide your location from Find My Friends or change what they can see on social media. If you want to hide your location or profile picture from someone, you need to adjust those settings separately in each app.

What if I block someone and then they call from a different number?

Blocking stops calls from that specific phone number or contact. If they call from a different number, you will receive the call normally. You would need to block the new number separately.

Does blocking someone delete our old text messages?

No. Old messages stay in your Messages app. You can still read past conversations with a blocked person, but you will not receive new messages from them until you unblock them.

Can I block someone without them being in my contacts?

Yes. You can block a phone number or contact even if you have not saved them to your contacts. You can block from recent calls in the Phone app, or add them through Settings without having them saved as a contact.
