Blocking someone on iPhone is straightforward, but people often wonder what the other person actually experiences. Here's exactly what happens on both ends.
What Happens to Calls
When the blocked person calls you:
- Their call goes straight to voicemail after one ring (or no ring)
- They can leave a voicemail, but it goes to a separate "Blocked Messages" folder you can check if you want
- You receive no notification of the call
- They have no way of knowing they've been blocked versus you just not answering
What Happens to iMessages and Texts
When the blocked person texts you:
- iMessage (blue bubble): their message shows "Delivered" on their end — it never actually reaches you
- SMS (green bubble): they get no delivery confirmation at all
- You never see any of their messages
- They receive no notification that they've been blocked
This is the part that trips people up — the sender has no clear signal that they're blocked. iMessages will still show "Delivered" in many cases, which is deliberately ambiguous.
What Happens to FaceTime
FaceTime calls from blocked contacts go unanswered — the blocked person's phone rings endlessly (or until they give up) with no indication the call is being ignored or that they're blocked.
What the Blocked Person Sees
The short answer: nothing definitive. They don't get a message saying "You've been blocked." Calls seem to go to voicemail (could be you're busy), texts seem to send (but you never receive them), FaceTime rings but isn't answered. It's designed to be ambiguous.
How to Block Someone on iPhone
From a call or message:
- Open the contact or conversation
- Tap the name or number at the top
- Scroll down → Block this Caller
From Contacts:
- Open the Contacts app → find the person
- Scroll to the bottom → Block this Caller
From Settings:
- Settings → Phone → Blocked Contacts → Add New
Does Blocking Work Across Apps?
Blocking someone on iPhone only affects calls, texts, and FaceTime. It does not block them on WhatsApp, Instagram, Snapchat, or any other app — those have their own separate blocking systems.
Can You Still See Old Messages?
Yes. Blocking someone doesn't delete any previous conversations. All old messages remain visible in your Messages app. If you want to remove them, you need to manually delete the conversation.
How to Unblock Someone
Settings → Phone → Blocked Contacts → swipe left on the contact → Unblock. Or go to the contact in your address book → scroll down → Unblock this Caller.
