How to Effectively Block Scam Calls on Your Mobile Device

Scam calls are a pervasive nuisance, but you can take control by implementing effective strategies to block them.

What Are Scam Calls?

Scam calls are unsolicited communications from individuals or organizations attempting to deceive you into providing personal information, money, or access to your devices. They often impersonate legitimate entities like banks, government agencies, or tech support services.

How Do Carriers Help Block Scam Calls?

Many mobile carriers offer built-in features to help identify and block scam calls:

  • AT&T: Provides a service called AT&T Call Protect, which automatically blocks suspected scam calls and alerts you to potential spam.

  • Verizon: Offers Verizon Call Filter, which identifies and blocks spam calls, and provides a spam risk indicator.

  • T-Mobile: Features Scam Shield, which includes scam call blocking and a scam ID to warn you of potential spam.

These services are typically available at no extra cost, but some carriers may offer premium versions with additional features.

What If My Carrier Doesn't Offer Scam Call Blocking?

If your carrier doesn't provide effective scam call blocking, or if you're seeking enhanced protection, third-party applications can be a valuable solution.
