How to Effectively Screen Unknown Callers and Block Spam Calls

Unwanted spam calls are a pervasive nuisance, often disrupting daily life and posing potential security risks. Effectively screening unknown callers and blocking spam is essential for maintaining peace of mind.

Why Are Spam Calls a Problem?

Spam calls can range from annoying telemarketing pitches to fraudulent schemes aiming to steal personal information. In 2024, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person per month. (antivirus.com)

How Can You Identify Spam Calls?
