What does 'Scam Likely' mean on my phone?

It is a label T-Mobile (and other carriers via STIR/SHAKEN) add to calls coming from numbers their fraud-detection systems have flagged. The call still rings unless you turn on blocking.

How do I block Scam Likely calls on iPhone?

Settings → Apps → Phone → Silence Unknown Callers (on). For T-Mobile, also dial #662# to enable Scam Block at the network level so flagged calls never reach you.

How do I block Scam Likely calls on Android?

Open Phone app → Settings → Caller ID & spam → enable both 'Caller ID & spam' and 'Filter spam calls'. On Pixel, turn on Call Screen.

Will blocking Scam Likely calls block legitimate businesses?

Occasionally yes — pharmacies, schools and delivery drivers sometimes call from unverified numbers. Voicemail still works, and you can whitelist contacts you save.

Is the Do Not Call Registry effective?

It stops legal telemarketers but not overseas scam operations. Carrier blocking plus phone-level filtering is far more effective against scam likely calls.

Block Scam Likely calls on iPhone

Settings → Apps → Phone → Silence Unknown Callers — toggle on. Calls from numbers not in your contacts, recent outgoing list, or Siri Suggestions are sent straight to voicemail. Combine with carrier Scam Block for maximum coverage.

Block Scam Likely calls on Android

Open the Phone app → ⋮ menu → Settings → Caller ID & spam. Turn on both 'See caller and spam ID' and 'Filter spam calls'. On Pixel, also enable Call Screen — Google Assistant answers and screens the call before it rings.

What never to do

Three things that make scam calls worse:

Pressing '1' to 'be removed from the list' — confirms a live number.
Saying 'Yes' to 'Can you hear me?' — recorded for fraudulent authorisations.
Calling the number back — many are toll-trap numbers that bill per minute.
