These calls can range from fraudulent offers to phishing attempts, posing significant risks to personal and financial security. In this guide, we'll explore effective strategies to block these unwanted calls, highlighting Robokiller as a top solution.

The prevalence of such calls has escalated, with Americans receiving over 52.5 billion robocalls in 2025, averaging roughly 13–15 spam calls per person per month. (antivirus.com)

How Can Built-in Phone Features Help Block Scam Calls?

Modern smartphones come equipped with features designed to filter out unwanted calls:

iPhone Users: Activate "Silence Unknown Callers" by navigating to Settings > Phone > Silence Unknown Callers. This feature sends calls from numbers not in your contacts directly to voicemail. (onlinethreatalerts.com)
Android Users: Enable spam protection by opening the Phone app, selecting Settings > Caller ID & spam, and toggling on "See caller and spam ID" and "Filter spam calls." (onlinethreatalerts.com)
