  2. Find the spam call you want to report.
  3. Tap the “i” icon next to the number.
  4. Scroll down and select “Report Junk.”

Blocking Unknown Callers

For those who want to take an even more aggressive approach, it’s possible to block all calls from unknown numbers. However, be cautious, as this may result in missed important calls.

To block all calls from unknown numbers:

  1. Open the “Settings” app on your iPhone.
  2. Scroll down and tap “Phone.”
  3. Toggle on “Silence Unknown Callers.”

Regularly Updating iOS

Apple continually releases updates to its iOS operating system, and these updates often include improvements to spam call protection. It’s crucial to keep your iPhone up to date to benefit from the latest security enhancements.

Additional Tips and Tricks

Here are some additional tips and tricks to enhance your spam call protection:

  • Use a Call Screening Service: Some carriers offer call screening services that can automatically identify and block spam calls.
  • Avoid Answering Unknown Numbers: If you receive a call from an unknown number, let it go to voicemail and return the call if it’s legitimate.
  • Be Wary of Caller ID Spoofing: Scammers can manipulate caller IDs, so don’t rely solely on caller ID information.
  • Educate Yourself: Stay informed about common spam call tactics and scams to recognize potential threats.

The Future of Spam Call Blocking

The battle against spam calls continues to evolve, and as technology advances, so do the methods used by spammers. The future of spam call blocking may involve even more sophisticated AI-based solutions and improved regulation to crack down on spam call operations.

While blocking spam calls is essential for personal privacy and security, it’s important to be aware of the legal implications. Different countries have varying laws regarding call blocking and telemarketing. It’s advisable to familiarize yourself with local regulations to ensure compliance.


Blocking spam calls on your iPhone is not only possible but also essential for maintaining your privacy and peace of mind. By utilizing built-in features, exploring third-party apps, and staying informed about the latest spam call tactics, you can significantly reduce the annoyance and potential risks associated with spam calls.
