Block all calls at once using Do Not Disturb

The fastest way to stop all incoming calls on your iPhone is to turn on Do Not Disturb. This silences calls, texts, and notifications without blocking individual numbers. When Do Not Disturb is on, callers hear a busy signal or are sent to voicemail, but they do not know you have blocked them.

Open Settings, tap Do Not Disturb, and toggle it on. You can set it to stay on all the time, or schedule it to turn on and off at specific times — for example, every night from 10 p.m. to 7 a.m. If you want certain people to reach you even when Do Not Disturb is active, scroll down to "Allow Calls From" and select Favorites, Recents, or Contacts.

Do Not Disturb does not permanently block anyone. You can turn it off whenever you want to receive calls again. This makes it useful if you need a break from calls but do not want to block specific people forever.

Key Takeaways

  • Do Not Disturb silences all calls and sends them to voicemail without the caller knowing they are blocked.
  • You can schedule Do Not Disturb to turn on and off automatically at times you choose, like during work hours or sleep.
  • Block individual numbers permanently in the Phone app by tapping the info icon next to a contact and selecting "Block This Caller."
  • Blocked callers cannot reach you by phone, FaceTime, or Messages, and their calls go straight to voicemail without ringing your phone.
  • You can view and unblock numbers anytime in Settings under Phone or Messages, depending on where you blocked them.

Block individual numbers permanently

If you want to stop calls from specific people rather than everyone, open the Phone app and find the number or contact you want to block. Tap the info icon (a circle with an "i" inside) next to their name or number, scroll down, and tap "Block This Caller." The person is now blocked on calls, FaceTime, and Messages.

You can also block someone from a text message or FaceTime call. In Messages, swipe left on the conversation and tap the trash icon, then tap "Block This Caller" from the menu that appears. In FaceTime, tap the info icon during or after a call and select "Block This Caller."

Blocked numbers cannot call you, text you, or reach you on FaceTime. Their calls go straight to voicemail, and they do not receive a notification that they are blocked — the call straightforward fails on their end. You will not see their calls, texts, or FaceTime requests on your phone.

Use Focus modes to block calls by category

Focus modes let you block calls from everyone except people you choose, organized by what you are doing. Open Settings, tap Focus, and select an existing mode like Work, Sleep, or Driving, or create a new one by tapping the plus icon.

In the Focus settings, tap "Allow Calls From" and choose who can reach you — Favorites, Recents, Contacts, or specific groups. Everyone else is blocked from calling you while that Focus is active. You can set each Focus to turn on automatically at certain times or locations, so your phone switches modes without you having to do anything.

Focus modes are different from Do Not Disturb because they let you stay reachable to specific people while blocking everyone else. For example, you could create a "Family Only" Focus that allows calls from your family contacts but blocks all other callers, and set it to turn on after 6 p.m.

Silence unknown callers and spam

If you receive many calls from numbers not in your contacts, turn on "Silence Unknown Callers" in Settings. Open Settings, tap Phone, and toggle on "Silence Unknown Callers." Calls from numbers not saved in your contacts go straight to voicemail and do not ring your phone.

This setting does not block anyone — it just silences the ring. Callers can still leave voicemails, and you can call them back if you check your voicemail. Calls from people in your contacts, Favorites, and recent calls still ring normally.

You can also report spam calls directly in the Phone app. After a call ends, tap the info icon next to the number and select "Report as Junk." This helps Apple identify spam patterns, though it does not block future calls from that number automatically.

Unblock numbers you have blocked

To see all the numbers you have blocked, open Settings and tap Phone. Scroll down to "Blocked Contacts" and you will see a list of every number you have blocked on calls. Tap "Edit" in the top right, then tap the red minus icon next to a number and tap "Unblock" to remove them from your blocked list.

You can also unblock someone from Messages or FaceTime. In Messages, go to Settings, tap Messages, scroll to "Blocked Contacts," and tap Edit to remove someone. In FaceTime, go to Settings, tap FaceTime, scroll to "Blocked Contacts," and tap Edit.

Once you unblock a number, that person can call, text, and FaceTime you again, and their calls will ring your phone normally. There is no notification sent to them when you unblock them.

What happens when you block a call

When you block someone on your iPhone, they cannot reach you by phone, text, or FaceTime. Their call goes to your voicemail, but your phone does not ring and you do not see a notification. They do not receive a message saying they are blocked — the call straightforward fails on their end, usually with a message like "call failed" or "the person is not available."

Blocked callers can still leave voicemails, which appear in a separate "Blocked Messages" section in your voicemail. You can listen to them if you want, but you will not be notified when they arrive. Text messages from blocked numbers do not appear in your Messages app at all.

If someone you have blocked tries to call you using a different number, that call will ring normally because the block applies only to the specific number you blocked. They would need to use a completely different phone to reach you.

Combine blocking methods for maximum control

You can use multiple blocking methods together to control your calls more precisely. For example, you could turn on "Silence Unknown Callers" to block spam, create a Work Focus that allows only your boss and team to call you, and block specific people who have harassed you.

Do Not Disturb and Focus modes work together — if both are on, the Focus mode settings take priority. If you have a Sleep Focus that allows only Favorites to call, and Do Not Disturb is also on, only your Favorites can reach you.

Test your settings by having someone call you from a number you have blocked or silenced. Their call should go to voicemail without ringing your phone. If it rings, check that your blocking method is actually turned on in Settings.

Frequently Asked Questions

Can someone tell if I have blocked them?

No. When you block someone, their call goes to voicemail without any notification that they are blocked. They may suspect it if calls consistently fail, but your iPhone does not send them a message or alert saying they are blocked.

Will blocked callers still reach my voicemail?

Yes. Blocked callers can leave voicemails, but they appear in a separate "Blocked Messages" section and you will not receive a notification when they arrive. You can listen to them anytime by opening Voicemail in the Phone app.

Can I block calls but still receive texts from someone?

No. Blocking someone in the Phone app blocks them on calls, FaceTime, and Messages all at once. If you want to block only calls but allow texts, you would need to block them in Messages separately, though this is not a standard option — you would instead need to manage the conversation manually.

What is the difference between Do Not Disturb and blocking?

Do Not Disturb silences all calls and sends them to voicemail, but you can turn it off anytime. Blocking is permanent until you unblock someone. Do Not Disturb affects everyone; blocking affects only specific numbers or people you choose.

If I turn on Silence Unknown Callers, will I miss important calls?

Possibly. Silence Unknown Callers blocks calls from numbers not in your contacts, so if someone new tries to reach you, their call goes to voicemail. Callers in your contacts, Favorites, and recent calls still ring normally, so people you have talked to before can still reach you.
