Protect Your iPhone from Spam Calls: Top Apps and Features

Spam calls are a persistent nuisance for iPhone users, often disrupting daily life and posing 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. They can range from harmless promotions to fraudulent schemes aiming to steal personal information. According to a report by the Federal Communications Commission (FCC), Americans received over 4 billion robocalls in 2020 alone. (tomsguide.com)

How Can I Block Spam Calls on My iPhone?

Apple offers built-in features and supports third-party apps to help block spam calls. Here's how you can utilize both:

1. Enable "Silence Unknown Callers"

This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions. To activate it:

  1. Open Settings.
  2. Tap Phone.
  3. Toggle on Silence Unknown Callers.

While effective, be aware that this may also silence important calls from unknown numbers. (tomsguide.com)

2. Use Third-Party Spam Call Blocking Apps

Several apps are designed to identify and block spam calls:

  • Robokiller: Blocks 99% of robocalls and texts, offering customizable call filters and fun anti-spam audio replies. (avnexo.com)
