The short answer.

How to stop spam calls on iPhone

Open Settings, tap Apps, then Phone. Set Screen Unknown Callers to Ask Reason for Calling (iOS 26 Call Screening) or Silence, and under Call Filtering turn on Spam. Then turn on your phone company’s free filter and add your number to the Do Not Call Registry.

Some spam still gets through, because a scammer can show any number. Vicem is an AI on its own number that answers the calls you miss and turns scam callers away.
