What blocking does on an iPhone

When you block someone on an iPhone, that person can no longer call you, text you, or reach you through FaceTime. Their calls go straight to voicemail without ringing your phone. Text messages they send disappear — you won't see them, and they won't get a delivery confirmation. If they try to FaceTime you, the call won't go through. They also can't see when you're online in iMessage, and they can't add you to group chats.

Blocking is permanent until you unblock the person. It works across all Apple services on your phone — Messages, Phone, FaceTime, and iCloud. The person you block won't receive a notification that you blocked them, but they may figure it out when their calls stop connecting and their messages don't deliver.

Key Takeaways

  • Open the Phone, Messages, or FaceTime app, find the contact, and tap the info icon to reach the block option.
  • Blocked calls go straight to voicemail, and blocked texts disappear without a delivery confirmation.
  • You can unblock someone at any time through the same contact info screen.
  • Blocking someone on your iPhone does not delete your conversation history with them.

How to block someone using the Phone app

Open the Phone app and go to the Recents tab at the bottom. Find the person you want to block and swipe left on their name. A red "Block this Caller" button appears. Tap it, then confirm by tapping "Block Contact" in the popup window.

If you want to block someone who isn't in your recent calls, open the Contacts app instead. Find their name, tap the info icon (a circle with an "i" inside), scroll down, and tap "Block this Caller". The same confirmation popup appears.

How to block someone in Messages

Open the Messages app and find the conversation with the person you want to block. Swipe left on their name or message thread. A red "Block" button appears. Tap it, then tap "Block Contact" to confirm.

You can also open the conversation, tap the contact name or number at the top of the screen, tap the info icon, scroll down, and select "Block this Caller". Both methods do the same thing — they block the person across all Apple services, not just Messages.

How to block someone in FaceTime

Open FaceTime and find the person in your recent calls or contacts. Swipe left on their name, and a red "Block" button appears. Tap it and confirm. Alternatively, tap the info icon next to their name, scroll down, and tap "Block this Caller".

Blocking in FaceTime blocks the person from calling you through any Apple service, not just FaceTime. They won't be able to reach you by phone, text, or video call.

How to unblock someone

Open the Phone app, go to the Contacts tab, and find the person's name. Tap the info icon, scroll down, and you'll see "Unblock this Caller" instead of the block option. Tap it and confirm. The person is now unblocked and can call, text, and FaceTime you again.

You can also unblock someone through Messages or FaceTime using the same method — find their contact, tap the info icon, and select "Unblock this Caller". Unblocking restores their ability to reach you through all Apple services when ready.

What happens to old messages and calls

Blocking someone does not delete your conversation history with them. If you had text messages, calls, or FaceTime records with that person before you blocked them, those remain in your phone. You can still see them in the Messages app or call history.

However, once you block someone, you won't receive any new messages or calls from them. If you unblock them later, new messages will come through normally, but they won't see the old conversation history on their end — only what they sent and received before the block.

Blocking someone who isn't in your contacts

If someone calls or texts you and they're not saved in your contacts, you can still block them. In the Phone app, go to Recents, find the number, and swipe left. Tap "Block this Caller". In Messages, swipe left on the conversation and tap "Block".

When you block a number that isn't in your contacts, future calls and texts from that number won't reach you. If the person later saves themselves under a different number, that new number won't be blocked — you'd have to block each number separately.

Frequently Asked Questions

Will the person I block know that I blocked them?

No, they won't get a notification. However, they may realize it when their calls go to voicemail every time, their texts don't deliver, and they can't reach you on FaceTime. There's no way for them to confirm it through the phone itself.

Can I block someone and still see their messages?

No. Once you block someone, their messages won't come through at all. You won't see new texts, and they won't get a delivery confirmation. Your old messages with them stay in your phone, but new ones from them are blocked.

What if someone blocks me on their iPhone?

Your calls will go straight to voicemail without ringing their phone. Your texts will appear to send normally on your end, but they won't deliver. You won't get a notification that you're blocked, but the pattern of calls going to voicemail and texts not delivering is usually a sign.

Can I block someone from a group chat?

Blocking someone removes them from group chats you're in and prevents them from adding you to new ones. However, if they create a group chat and add you, you'll still receive those messages unless you block them first. Blocking is the most complete way to prevent contact.

If I unblock someone, will they see old messages?

No. Unblocking just restores their ability to reach you going forward. They won't see any messages you sent or received while they were blocked. Old conversation history on your phone stays the same whether someone is blocked or not.
