How to Stop Spam Calls on iPhone (Settings That Work)
Car warranty offers, fake bank alerts, “your package is delayed” and calls that hang up the second you answer. Spam calls are one of the most common complaints iPhone owners have, and they never seem to stop on their own.
The good news is that your iPhone has strong built-in tools for this, and newer iOS versions can even ask unknown callers why they are calling before your phone rings. This guide covers every option, from settings that take 30 seconds to carrier tools and the Do Not Call Registry, plus tips from Reddit users who finally got their phones quiet again.
Quick answer: To stop spam calls on iPhone, go to Settings, then Apps, then Phone. Under Screen Unknown Callers, choose Ask Reason for Calling or Silence, and under Call Filtering turn on the spam and unknown caller filters. Block repeat numbers from the Recents list by tapping the info icon and choosing Block this Caller. Turn on your carrier’s free spam blocking, add your number to the National Do Not Call Registry, and never answer or call back unknown numbers.
Method 1: Screen or Silence Unknown Callers
This is the most effective setting. According to Apple Support:
- Open Settings, tap Apps, then Phone.
- Find Screen Unknown Callers.
- Choose Ask Reason for Calling to have callers explain who they are before your phone rings, or Silence to send unknown numbers straight to voicemail.
On older iOS versions, look for Silence Unknown Callers under Settings, then Phone. Important: save doctors, schools, delivery services and anyone you expect to hear from to your Contacts so their calls still ring.
Method 2: Turn On Call Filtering
In the same Phone settings, scroll to Call Filtering and turn on the spam filter and the Unknown Callers filter. Missed calls and voicemails from spam and unknown numbers are moved into separate lists, so your main Recents stay clean. Tap the Filter button in the Phone app to check them.
Method 3: Block Specific Numbers
- Open the Phone app and go to Recents.
- Tap the info (i) icon next to the number.
- Scroll down and tap Block this Caller, then confirm.
Blocking works best for repeat callers. Many spammers switch numbers constantly, which is why the screening and filtering settings above matter more.
Method 4: Use Your Carrier’s Free Spam Blocking
| Carrier | Free tool |
|---|---|
| AT&T | ActiveArmor |
| Verizon | Call Filter |
| T-Mobile | Scam Shield |
These services flag or block suspected spam before it reaches your phone. Turn them on in the carrier’s app or account settings.
Method 5: Install a Call Blocking App
Apps like Hiya, Truecaller or RoboKiller add larger spam databases. After installing, go to Settings, then Apps, then Phone, then Call Blocking & Identification, and switch the app on. Check each app’s privacy policy, since some read contact data.
Method 6: Join the Do Not Call Registry
Add your number for free at donotcall.gov. Legitimate telemarketers must stop calling, though scammers ignore it. The same site lets you report unwanted calls, which helps regulators track down bad actors.
