How to Block Unwanted Sales Calls: A Guide for Everyday Users

Unwanted sales calls, commonly known as robocalls, are a persistent nuisance for many phone users. These unsolicited calls can disrupt daily life and, in some cases, lead to fraudulent schemes. Fortunately, there are effective solutions available to help you 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 telemarketing purposes. They can be intrusive, time-consuming, and sometimes deceptive, leading to potential scams. In the United States, consumers reported losing approximately $150 million to phone scams in 2022 alone. (ir.iac.com)

How Can I Block Unwanted Sales Calls?

To effectively block unwanted sales calls, consider the following strategies:

  • Register with the National Do Not Call Registry: This free service allows you to opt out of receiving unsolicited sales calls. While it reduces the number of such calls, it doesn't eliminate them entirely.

  • Use Call-Blocking Apps: These applications can identify and block robocalls in real-time. They often maintain databases of known spam numbers and can filter out unwanted calls.

  • Manually Block Numbers: Most smartphones allow you to block specific numbers. However, this method is time-consuming and may not be effective against constantly changing spam numbers.

What Is Robokiller and How Does It Work?

Robokiller is a leading call-blocking app designed to eliminate 99% of unwanted phone calls. It utilizes advanced algorithms and a global database of over 600 million spam numbers to identify and block robocalls. (ir.iac.com)

Key Features of Robokiller:

  • Real-Time Call Blocking: Intercepts and blocks spam calls as they arrive, preventing interruptions.

  • Answer Bots: Engages with spam callers using pre-recorded messages, wasting their time and resources.

  • Spam Text Blocking: Filters out unwanted text messages, reducing potential scams.

  • Customizable Settings: Allows users to adjust blocking preferences and manage blocked numbers.

How Does Robokiller Compare to Other Call-Blocking Apps?

When compared to other call-blocking apps, Robokiller stands out due to its comprehensive features and effectiveness. For instance, a study found that Robokiller was able to block 9 out of 10 spoofed robocall numbers, demonstrating its reliance on both blacklists and call content analysis. (repository.gatech.edu)

In contrast, some competitors may rely solely on blacklists, which can be less effective against new or spoofed numbers. Robokiller's combination of real-time blocking, answer bots, and spam text filtering provides a more robust solution.

Are There Any Drawbacks to Using Robokiller?

While Robokiller offers many benefits, some users have reported issues:

  • Technical Glitches: Some users have experienced problems with the app's blocking feature, where certain numbers are not blocked as expected. (apps.apple.com)

  • Customer Service Concerns: There have been complaints about the responsiveness and helpfulness of Robokiller's customer support. (trustpilot.com)
