Spam calls have become a pervasive nuisance, with millions of Americans receiving unwanted solicitations daily. In 2026, identifying and blocking these calls is more crucial than ever. Here's how you can protect yourself:
What Are Spam Calls and Why Are They a Problem?
Spam calls are unsolicited communications, often from automated systems, aiming to sell products, services, or gather personal information. They can be disruptive and, in some cases, fraudulent. The Federal Communications Commission (FCC) reports that robocalls account for a significant portion of unwanted calls in the U.S.

What Built-in Features Help Block Spam Calls?

-
iPhone: iOS 26 introduced "Call Screening," which prompts unknown callers to state their name and reason for calling.
