How to Block Spam Calls on Your Phone

Have you ever picked up your phone just to realize it’s another spam call or even a scam attempt? If this sounds familiar, you’re not alone. In the U.S., millions of people receive unwanted calls every single day. That’s why knowing how to block spam calls on your phone is not just convenient—it’s essential for your privacy and security.

Why blocking spam calls matters

Unwanted calls aren’t just annoying. They can affect your life in different ways:

• Safety: many scams start with a phone call.

In other words, blocking spam calls is about protecting your time and your personal information.
