How to Block Spam Calls on iPhone (No App Required)

Below is the iPhone call blocking settings guide that eliminates unwanted calls and texts. Grab your phone and work through each toggle – it’s fast, free, and stays entirely within iOS.

1. Open Settings → Phone

Launch Settings, scroll down, and tap Phone. This hub holds every call‑related option.

2. Tap “Call Blocking & Identification”

Inside the Phone menu, select Call Blocking & Identification. You’ll see any numbers you’ve already blocked and a few toggle switches.

3. Add Numbers to “Blocked Contacts”

Tap Add New to type a spam number, or choose a recent call from your log.
Once added, the number is sent straight to voicemail.

Pro tip: Keep a short list of the worst spam prefixes and add them here regularly. It’s a tiny habit that blocks dozens of calls.

4. Enable “Silence Unknown Callers”

Toggle Silence Unknown Callers on. This is the core how to block unknown numbers on iPhone setting: calls from numbers not in your contacts, recent calls, or Siri suggestions go directly to voicemail while still appearing in your missed‑call log.

5. Filter Unknown Text Senders

Open Settings → Messages and switch on Filter Unknown Senders. Messages from unfamiliar numbers are moved to a separate tab, keeping your main inbox clean.

6. (Optional) Use “Do Not Disturb” for Unknown Callers

Go to Settings → Focus → Do Not Disturb.
Tap People → Calls From and choose All Contacts.

This ensures only saved contacts can ring through, perfect for meetings or quiet moments.

7. Periodically Review Recent Calls

Spammers sometimes spoof saved contacts. Scan your recent calls list; if a number looks suspicious, tap the i icon and select Block this Caller. A quick habit that adds an extra safety net.
