Protect Your iPhone from Spam Calls: Top Apps and Features

Spam calls are a persistent nuisance for iPhone users, often leading to interruptions and potential security risks. Fortunately, there are effective strategies and applications available to mitigate this issue.

How Can I Block Spam Calls on My iPhone?

Apple offers built-in features and supports third-party applications to help users block unwanted calls.

Built-in Features: Silence Unknown Callers

iOS includes a feature called "Silence Unknown Callers," which sends calls from unknown numbers directly to voicemail. To activate this:

  1. Open Settings.
  2. Tap on Phone.
  3. Select Silence Unknown Callers and toggle it on.

While this feature is effective, it may also silence calls from legitimate contacts not saved in your address book. (techradar.com)

Third-Party Apps: Enhancing Call Blocking

For a more robust solution, third-party apps can provide advanced spam call blocking capabilities. These apps utilize extensive databases and real-time reporting to identify and block unwanted calls.

What Are the Best Apps to Block Spam Calls on iPhone?

Several applications stand out in the realm of spam call blocking:
