Unwanted calls, commonly known as robocalls or spam calls, are a persistent nuisance for iOS users. These unsolicited calls can disrupt daily life and compromise privacy. Fortunately, there are several effective strategies to mitigate this issue on your iPhone.
What Built-in Features Does iOS Offer to Block Unwanted Calls?
iOS provides several built-in features to help users manage and block unwanted calls:
-
Silence Unknown Callers: This feature automatically silences calls from numbers not saved in your contacts, recent calls, or Siri Suggestions. The calls are sent directly to voicemail, and you can view them in your recent calls list. To enable this, go to Settings > Phone > Silence Unknown Callers.

Call Blocking and Identification: iOS allows third-party apps to integrate with the Phone app to identify and block spam calls. You can enable these apps by navigating to Settings > Phone > Call Blocking & Identification.
