Scam calls are a pervasive issue in the United States, with Americans receiving over 50 billion robocalls in 2024 alone. (whocalledus.net) These unsolicited calls can range from fraudulent offers to phishing attempts, making it essential to have reliable tools to block them. Fortunately, several free apps are available to help you combat this problem effectively.
What Are the Best Free Apps to Block Scam Calls?
Several free applications have been developed to identify and block scam calls, leveraging extensive databases and advanced algorithms. Here are some top recommendations:
RoboKiller
RoboKiller is a comprehensive call-blocking app that uses a combination of blacklisting, whitelisting, and identification methods to prevent robocalls and spam calls. Beyond call blocking, it offers versatile features like call screening, forwarding, and voicemail transcription.

Hiya

How Do These Apps Compare to RoboKiller?
While RoboKiller offers a comprehensive suite of features, including call screening and voicemail transcription, it is a paid service. In contrast, Hiya and Truecaller provide robust call-blocking capabilities for free, making them accessible options for users seeking to block scam calls without incurring additional costs.
Are There Carrier-Provided Solutions Available?
Yes, several mobile carriers offer free tools to help block scam calls:
-
T-Mobile Scam Shield: This service identifies and blocks suspicious calls before they reach your phone. T-Mobile customers can activate Scam Shield by dialing #ONB# (#662#). (consumerreports.org)

Verizon Call Filter: Verizon automatically enrolls eligible customers in the free version of Call Filter, which detects spam and blocks high-risk calls. Users can activate Call Filter by dialing #ACPT# (#2278#). (consumerreports.org)

How Do These Carrier Solutions Compare to Third-Party Apps?
Carrier-provided solutions like T-Mobile Scam Shield, Verizon Call Filter, and AT&T Call Protect offer basic protection against scam calls. However, third-party apps like Hiya and Truecaller often provide more comprehensive features, such as detailed caller information and community-driven spam reporting, which can enhance the accuracy and effectiveness of scam call blocking.
How Can I Protect Myself from Scam Calls?
In addition to using call-blocking apps and carrier services, consider the following steps to protect yourself:
-
Register with the National Do Not Call Registry: This free service allows you to opt out of receiving unsolicited marketing calls. You can register at donotcall.gov.

Conclusion
While scam calls remain a significant concern, utilizing free apps like Hiya and Truecaller, along with carrier-provided solutions, can significantly reduce the number of unwanted calls you receive.
