Scam Shield™. Fewer scam calls. Period.

T-Mobile has the largest, fastest and now according to umlaut, most reliable 5G network in America. And with our advanced scam blocking protection built into our core network we’re protecting every customer from spam and scam calls.

Your ultimate call control center.

The Scam Shield app gives you control over T-Mobile's anti-scam protections like Scam Block, and Caller ID, and is available to all eligible customers.

Scam Shield's five layers of protection:

Advanced network technology.

Our supercharged network analyzes every call using A.I., machine learning, and patented technologies. And our defenses update every six minutes to stay ahead of scammers.

Built-in protection.

Americans get billions of scam and robocalls every year. But Scam ID and Scam Block technologies identify and help stop them—before you ever get the call.

Know who's calling.

If available, you'll see a caller's information, even if they're not in your contact list. With Scam Shield, full Caller ID access is automatically included. All you need to do is enable it from within the app.



Keep your personal number personal.

Scam Shield gives you an extra PROXY number that you can use when you don’t want to share your private phone number.
