Yes, some apps offer free versions with basic features:

How Do These Apps Work?

These applications function by integrating with your iPhone's call system to identify and block unwanted calls:

  1. Database Matching: They maintain extensive databases of known spam numbers.

  2. Call Identification: When a call comes in, the app checks the number against its database.

  3. Blocking or Alerting: If a match is found, the app either blocks the call or alerts you, depending on your settings.

How to Set Up Call Blocking on Your iPhone

To enable call blocking and identification:

  1. Install the App: Download your chosen app from the App Store.

  2. Grant Permissions: Allow the app to access your contacts and enable call blocking.

  3. Configure Settings: Adjust the app's settings to suit your preferences.

Are There Built-in iOS Features to Block Unwanted Calls?

Yes, iOS offers a built-in feature called "Silence Unknown Callers":

  1. Navigate to Settings: Open the Settings app on your iPhone.

  2. Select Phone: Tap on "Phone."

  3. Enable Silence Unknown Callers: Toggle on the "Silence Unknown Callers" option.

This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions, sending them directly to voicemail. (techradar.com)

Conclusion

Blocking unwanted calls on your iPhone is essential for maintaining privacy and reducing interruptions. While built-in features like "Silence Unknown Callers" offer basic protection, third-party apps like Robokiller provide more comprehensive solutions with advanced features.
