Spam calls are a persistent nuisance for iPhone users, often leading to interruptions and potential security risks. Fortunately, there are several effective solutions available to help you block these unwanted calls.

What Are Spam Calls and Why Are They a Problem?

Spam calls, also known as robocalls, are unsolicited calls made by automated systems or telemarketers.

How Can I Block Spam Calls on My iPhone?

There are two primary methods to block spam calls on your iPhone: using built-in features and third-party apps.

1. Built-in iPhone Features

Silence Unknown Callers

iOS offers a feature called "Silence Unknown Callers," which automatically silences calls from numbers not in your contacts, recent calls, or Siri Suggestions. To enable this:

Open Settings.
Tap Phone.
Toggle on Silence Unknown Callers.

This method ensures that unknown numbers are sent directly to voicemail, reducing interruptions. However, it may also silence important calls from unknown numbers. (techradar.com)
