How can I make sure my own business’ calls are not blocked?

The free website gives businesses the ability to register their business number(s) and name, so their calls to customers are recognized as legitimate.

I have a Prepaid account. Why isn’t the Scam Shield app working? 

The Scam Shield app does not support Prepaid accounts; however, you are eligible for free scam protection features such as Scam Block and Caller ID.

  • Enable Scam Block on Prepaid: Dial #662#
  • Enable Caller ID on Prepaid line: Dial #436#

Why did I get a message about Name ID? 

T-Mobile has migrated all the great features from Name ID into the Scam Shield app and has retired the Name ID version of the app. We encourage all of our Name ID customers to download the Scam Shield app. Download from the Google Play Store or download from the Apple App Store today to start enjoying the new UI and enhanced scam protections.  We no longer support previous versions of the Name lD app.
