In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person each month.

How Do Carrier-Provided Services Compare?
Major U.S. carriers offer their own call-blocking services:
-
AT&T Call Protect: Displays a “V” (for verified) on your caller ID for legitimate calls and blocks potentially fraudulent ones. (consumerreports.org)
-
T-Mobile Scam Shield: Identifies and tags suspicious calls, with Scam Block blocking calls before they ring. (consumerreports.org)
-
Verizon Call Filter: Detects spam and blocks high-risk calls, with a more robust paid version available. (consumerreports.org)
While these carrier services are convenient, third-party apps like Robokiller often provide more comprehensive protection and additional features.
Conclusion
For everyday users seeking to protect their U.S. phone numbers from sales calls, Robokiller offers a robust solution with high blocking accuracy and user-friendly features. While free alternatives exist, they may not offer the same level of protection or privacy. Carrier-provided services are convenient but may lack the comprehensive features found in dedicated apps. Ultimately, the choice depends on individual preferences and the specific features desired.
