T-Mobile® Scam Shield App – Block Scam & Unwanted Calls (Free & Premium) (2024)

When our network filters detect a potential scam call, we flag it and display it as Scam Likely on your device. This is made possible by our Scam ID technology which is embedded in our network and is enabled by default for all T-Mobile customers. No action is required on the part of customers to enable it, and it’s free.

PROXY gives you a free second number to help keep your primary number private, and is available to add to postpaid voice lines. One free PROXY number is available per account. You can check your calls and listen to your messages in the DIGITS app.

This offer is available for all postpaid voice plans; one free PROXY number is available per account. T-Mobile prepaid and Magenta for Business accounts with 13+ lines are not currently eligible.

Eligible customers can visit a T-Mobile store or dial 611 from your T-Mobile device to speak to a mobile expert, who will add the PROXY by DIGITS service to your account and set it up. For setup instructions, visit our support page.

Caller ID is the name of the caller as displayed on incoming calls made by the caller, and it’s a free feature for all T-Mobile customers with a capable device.

T-Mobile LineLink is a home phone service that uses the T-Mobile network and Voice over IP (VoIP) technology. Because T-Mobile LineLink uses the T-Mobile network, customers will get fewer scam calls with Scam ID and Scam Block, plus Caller ID.

T-Mobile customers can download the new Scam Shield app to get started. Eligible T-Mobile customers can also opt in by dialing #436#, via logging in to My T-Mobile, by visiting a T-Mobile retail store, or by dialing 611 from their T-Mobile phone to speak to a mobile expert.

Number Verified is T-Mobile's implementation of the new STIR/SHAKEN industry standards. T-Mobile was the first to implement STIR/SHAKEN for customers in January 2019. T-Mobile customers with an eligible device will see "Number Verified" on their screen when the calling number has been verified as authentic by the network. This means you can be assured that the phone number calling you is legitimate and hasn't been spoofed.

To edit the way your own Caller ID displays when you make calls, log in to My T-Mobile or the T-Mobile app and select >Profile>Line Settings>Caller ID, and enter your legal name or a commonly accepted variation. Profanity is not allowed. Changes will display within 72 hours.
If your name change isn't working, please dial 611 from your phone and we'll connect you to your Team of Experts.

We do our best to block spam and scam calls. Our network defenses update every 6 minutes. However, scammers sometimes still find a way around these network protections. While we continue to improve our network filters to block a higher percentage of all spam and scam calls, we encourage all our customers to report any spam or scam calls that we are unable to block. You can also report calls that you deem safe that might have been incorrectly blocked. There are two ways you can report calls:
From the app (Basic):
1. In the Scam Shield app, tap the Activity tab. A call log appears.
2. Select the number that needs to be reported, then tap Report
3. Choose the best category that represents the type of call, then tap Send Report > Done
From the app (Premium):
1. In the Scam Shield app, tap the Activity tab. Select the menu icon (three dots).
2. Tap Report and select the number that needs to be reported.
3. Choose the best category that represents the type of call, then tap Send Report > Done
From a web browser:
1. In a web browser, visit https://callreporting.t-mobile.com/
2. Fill out the form, then choose Review. Corrections are made within 48 hours of a verified request.

The free website https://calltransparency.com/ lets businesses register their business number(s) and name, so their calls to customers are recognized as legitimate.
