What Does 'Scam Likely' Mean — and How to Actually Block These Calls

If your phone shows “Scam Likely” instead of a name, that's a carrier warning — T-Mobile and Metro call it Scam ID. Their network flags a call it believes is probably spam or fraud, so you can decide whether to answer. Helpful, but it's only a heads-up: your phone still rings.

Carriers decide using network analytics and the STIR/SHAKEN system, which checks a digital “signature” on each call to confirm the number is genuine. Calls that fail the check, or come from numbers with a bad reputation, earn the label. It's smart, but it runs entirely on the carrier's side, on rules you can't see or adjust.

And it isn't a wall. Unless you turn on a separate “Scam Block” feature, the flagged call still rings through. Worse, scammers spoof caller ID — often faking a local number close to yours (“neighbor spoofing”) — so plenty of scam calls arrive with no warning at all.

Block-Spam closes that gap. Instead of just labeling a call, it blocks flagged numbers on your device, before your phone rings. You set the rules: a personal blocklist, wildcard patterns that silence an entire area code or prefix, and a whitelist mode where only your chosen contacts get through.

A community spam database keeps your protection current as users report new numbers — and none of it costs your privacy. Block-Spam never uploads your contacts; everything runs on your phone. Free for Android on Google Play and iPhone on the App Store.
