How to Block Scam Calls: A Guide for Everyday Users

Dealing with scam calls can be frustrating and time-consuming. Fortunately, there are effective strategies and tools available to help you block these unwanted calls and safeguard your privacy.

Summary

  • Understanding Scam Calls: Recognize the types and tactics used by scammers.
  • Built-in Phone Features: Utilize your device's native settings to block unknown or suspicious numbers.
  • Third-Party Apps: Explore dedicated applications designed to identify and block scam calls.
  • Carrier Services: Consider services offered by your mobile carrier for additional protection.
  • Best Practices: Adopt habits to minimize exposure to scam calls.

What Are Scam Calls and How Do They Work?

Scam calls are unsolicited communications from individuals or organizations attempting to deceive you into providing personal information, money, or access to your devices. Common tactics include impersonating legitimate entities like banks or government agencies, offering fake prizes, or creating a sense of urgency to pressure you into compliance.

How Can I Block Scam Calls Using My Phone's Built-in Features?

Both Android and iOS devices offer native features to help block unwanted calls:

  • iOS Devices: Go to Settings > Phone > Silence Unknown Callers. This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions.

  • Android Devices: The process varies by manufacturer, but generally, navigate to Phone > Settings > Blocked Numbers. Here, you can block unknown or private numbers.

While these features can reduce the number of scam calls, they may not block all unwanted calls.

What Are the Best Third-Party Apps for Blocking Scam Calls?

Several applications are designed to identify and block scam calls effectively:

  • Robokiller: This app uses a global database of analyzed calls and machine learning to identify and block spam calls. (antivirus.com)

  • Truecaller: With a large global database, Truecaller identifies unknown callers and blocks spam calls automatically. (antivirus.com)

  • Hiya: Hiya offers spam detection and call blocking features, with a focus on carrier-level protection. (antivirus.com)

These apps often provide both free and premium versions, with premium versions offering advanced features like enhanced spam blocking and an ad-free experience.

Are There Carrier Services That Help Block Scam Calls?

Many mobile carriers offer services to help block scam calls:

  • AT&T: Offers the AT&T Call Protect app, which provides spam call blocking and fraud alerts.

  • Verizon: Provides Verizon Call Filter, which identifies and blocks spam calls.

  • T-Mobile: Offers T-Mobile Scam Shield, which includes scam call blocking and caller ID features.

These services may be included in your plan or available for an additional fee.

What Are Some Best Practices to Avoid Scam Calls?

  • Do Not Share Personal Information: Never provide personal or financial information over the phone unless you are certain of the caller's identity.

  • Register with the National Do Not Call Registry: This can reduce the number of unsolicited calls you receive.

  • Be Cautious with Unknown Numbers: If you receive a call from an unknown number, let it go to voicemail.

  • Educate Yourself: Stay informed about common scam tactics and share this knowledge with friends and family.

What We Recommend

  • Use a Combination of Tools: Implement both built-in features and third-party apps for comprehensive protection.

  • Regularly Update Your Apps: Ensure your call-blocking apps are up to date to benefit from the latest features and databases.

  • Stay Vigilant: Always be cautious when receiving unsolicited calls and report any suspicious activity to the appropriate authorities.

By combining these strategies and tools, you can significantly reduce the number of scam calls you receive and protect your personal information.
