How to Block Automated Calls on iOS: A Guide for Everyday Users

Automated calls, commonly known as robocalls, are a persistent nuisance for iOS users in the United States. These unsolicited calls can range from telemarketing pitches to fraudulent schemes, disrupting daily life and compromising privacy. Fortunately, there are effective strategies to block these unwanted calls and regain control over your phone.

What Are Robocalls and Why Are They a Problem?

Robocalls are automated phone calls that deliver pre-recorded messages, often for marketing or scam purposes. They can be intrusive, time-consuming, and sometimes even dangerous if they involve fraudulent activities. In the U.S., millions of robocalls are made daily, making it essential to have reliable methods to block them.

How Can I Block Robocalls on My iPhone?

There are two primary methods to block robocalls on your iPhone:

  1. Enable Built-in Features: iOS offers a native feature called "Silence Unknown Callers." Activating this option sends calls from numbers not in your contacts directly to voicemail, effectively silencing potential robocalls. To enable this:
  • Go to Settings > Phone.
  • Toggle on Silence Unknown Callers.

While this method is straightforward, it may also silence calls from legitimate contacts not saved in your phonebook.

  1. Use Third-Party Apps: Dedicated call-blocking apps can provide more comprehensive protection by identifying and blocking known robocall numbers.

What Is Robokiller and How Does It Work?

Robokiller is a leading call-blocking app designed to stop up to 99% of robocalls and spam texts. It utilizes a global database of over 1.4 billion analyzed calls to instantly protect users from known phone scams. Its patented audio fingerprinting technology uses machine learning to identify and block unwanted calls. Additionally, Robokiller offers a feature called Robocall Revenge®, where spam calls are sent to clever recorded messages called Answer Bots, wasting the scammers' time. (robokiller.com)

How Effective Is Robokiller Compared to Other Apps?

Robokiller stands out in the market for its effectiveness and user satisfaction. With a 4.5 out of 5 rating based on over 413,000 reviews on the App Store, users frequently commend its ability to significantly reduce spam calls. (apps.apple.com) In contrast, other apps like Truecaller and Nomorobo also offer call-blocking features but may not match Robokiller's comprehensive database and unique features like Answer Bots.

Are There Any Drawbacks to Using Robokiller?

While Robokiller is highly effective, some users have reported occasional technical issues, such as the app not blocking certain numbers or requiring updates to function correctly. Additionally, the subscription model may be a consideration for some users. (trustpilot.com)

How Do I Set Up Robokiller on My iPhone?

  3. Grant Permissions: Allow the app to access your contacts and enable call blocking.
  4. Configure Settings: Customize your preferences, such as activating Answer Bots and setting up your block list.

Once set up, Robokiller will work in the background to identify and block robocalls, allowing you to enjoy a spam-free phone experience.

Are There Any Free Alternatives to Robokiller?
