How to Block Unknown Callers on iPhone


With the rollout of iOS 13, Apple is helping you put an end to the constant barrage of spam calls on your iPhone. The Silence Unknown Callers feature automatically silences all phone numbers from a number not found anywhere in your Mail, Messages or Contacts apps, and sends those unknown callers straight to voicemail. Examples of all instructions in the steps can be seen in the YouTube video below.
