How to stop spam calls on T-Mobile
T-Mobile’s free spam protection is Scam Shield: Scam ID labels likely scam calls Scam Likely, and Scam Block stops them before your phone rings. Dial #662# from your T-Mobile phone to turn Scam Block on, or switch it on in the T-Life app.
Scam Block can stop a call you want, and a scammer on a clean-looking number still gets through. Vicem, an AI with its own number, picks up the T-Mobile calls you miss and turns scam callers away.
