How it works:

Android offers several ways to block calls and SMS, ranging from built-in features to third-party apps:

*

Built-in Android features:

Most modern Android versions have a built-in call and SMS blocking feature. This usually involves going to the phone app[SQ]s settings or the messaging app[SQ]s settings, finding a "Blocked numbers" or similar option, and adding the number you want to block. The exact steps might vary slightly depending on your Android version and phone manufacturer.

*

Third-party apps:

Many apps in the Google Play Store offer advanced call and SMS blocking capabilities. These apps often have additional features such as:

Identifying spam callers:

These apps often use databases to identify potential spam numbers before you answer.
