Automated calls, commonly known as robocalls, are a persistent nuisance for mobile phone users in the United States. These unsolicited calls often come from telemarketers, scammers, or automated systems, disrupting daily life and potentially leading to fraudulent activities. Fortunately, several applications are designed to help users block these unwanted calls effectively.
What Are Robocalls and Why Are They a Problem?
Robocalls are automated telephone calls that deliver prerecorded messages, often for telemarketing or fraudulent purposes. They can be intrusive, time-consuming, and sometimes even dangerous if they involve scams. In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person per month. (antivirus.com)
