#662#and press the call button. - Wait for a confirmation message indicating that Scam Block is now active. (t-mobile.com)
3. Enable Silence Unknown Callers
This built-in iPhone feature sends calls from unknown numbers directly to voicemail:

This method ensures that only calls from your contacts and recent outgoing calls will ring through. (macobserver.com)
4. Block Specific Numbers Manually
To block individual numbers:
- Open the Phone app and tap on Recents.
