Unwanted calls, including robocalls and spam, are a persistent nuisance for many Americans. Fortunately, there are effective free solutions available to help block these interruptions. This guide explores the top options to help you regain control over your phone.
What Built-in Features Can Help Block Unwanted Calls?
iPhone Users:
-
Silence Unknown Callers: This feature automatically silences calls from numbers not in your contacts, sending them directly to voicemail. To activate, go to Settings > Phone > Silence Unknown Callers.
-
SMS Filtering: iOS can filter messages from unknown senders into categories like "Junk," "Promotions," and "Transactions." Enable this by navigating to Settings > Messages > Unknown & Spam.
Android Users:
- Spam Protection: Many Android devices offer built-in spam protection. For instance, Google's Phone app can identify and block suspected spam calls. To enable, open the Phone app, tap the three-dot menu, select Settings, then Caller ID & Spam.
How Do Carrier Services Assist in Blocking Unwanted Calls?
Major U.S. carriers provide free tools to help block spam and robocalls:

Verizon Call Filter: Verizon's free version automatically detects fraud calls and displays "Potential Spam" warnings.

What Are the Top Free Apps for Blocking Unwanted Calls?
Several free apps are highly effective in blocking unwanted calls:
