How to Block & Stop Scam Likely Calls (iPhone & Android)

“Scam Likely” is a carrier label, not a phone number — your carrier has already decided the call is fraud. You can silently send every one of them to voicemail in under two minutes, on any phone, for free. Here’s exactly how, by carrier and by operating system.

Fastest fix (60 seconds)

  • T-Mobile: dial #662# and press call.
  • iPhone: Settings → Phone → Silence Unknown Callers → ON.
  • Android: Phone app → Settings → Spam and Call Screen → Filter spam calls ON.

Block at the carrier (most effective)

Carrier-level blocking happens before the call ever reaches your phone, so your battery and notifications are untouched. All major US carriers now offer a free tier.

T-Mobile — Scam Shield (free)

  1. Open the T-Mobile or Scam Shield app, sign in.
  2. Tap Scam Shield → toggle Scam Block ON to silently reject any call T-Mobile labels Scam Likely.
  3. Without the app: dial #662# from your T-Mobile line and press call — confirmation text arrives in seconds.
  4. Turn off later with #632#.

AT&T — ActiveArmor (free)

  1. Install the AT&T ActiveArmor app and sign in with your wireless account.
  2. Tap Calls → Block → set Suspected Spam and Fraud Calls to Block.
  3. Optional: add personal block rules for specific numbers under Block List.

Verizon — Call Filter (free tier)

  1. Open Call Filter (preinstalled on most Verizon phones) or install it from the App Store / Play Store.
  2. Tap Spam Filter → set Filter Level to High to auto-reject high-risk spam.
  3. Free tier blocks the worst category; the paid Plus tier ($3.99/mo) adds caller ID and per-number reverse lookup.

Mint, Visible, US Mobile, Google Fi (MVNOs)

  1. MVNOs inherit the underlying carrier network — Mint/US Mobile use T-Mobile, Visible uses Verizon, Google Fi uses T-Mobile/US Cellular.
  2. Most MVNOs don't include the parent carrier's spam app. Use the OS-level silencing below instead, or layer a third-party app like Hiya, RoboKiller, or Truecaller.

iPhone — Silence Unknown Callers

  1. Open Settings → Apps → Phone (on iOS 18+) or Settings → Phone on iOS 17.
  2. Tap Silence Unknown Callers → toggle ON.
  3. Calls from anyone not in Contacts, Recents, or Siri Suggestions go straight to voicemail and appear in Recents — no ring, no Scam Likely banner interrupting you.
  4. Optional: Settings → Phone → Call Blocking & Identification — enable any installed spam-ID app (Hiya, Truecaller, RoboKiller).

Android — Spam & Call Screen

  1. Open the Phone app by Google (default on Pixel and most Android devices).
  2. Tap the three-dot menu → Settings → Spam and Call Screen.
  3. Toggle See caller and spam ID ON, then toggle Filter spam calls ON to silently send Scam Likely calls to voicemail.
  4. On Pixel: tap Call Screen → Unknown call settings → set Spam to Automatically screen. Decline and silently decline.
  5. Samsung phones: Phone app → menu → Settings → Block numbers → toggle Block unknown/private numbers and Caller ID and spam protection ON.

Don’t do these

  • A real bank, IRS, or utility will never call from Scam Likely — they use their own outbound IDs.
  • Pressing 1 to "speak to an agent" confirms your number is live and increases call volume.
  • Returning the missed call connects you to the scammer — never call back a Scam Likely number.
  • Spoofed neighbor numbers (same area code + prefix) are the same boiler rooms — Silence Unknown Callers catches them too.

FAQ

How do I block Scam Likely calls on iPhone?

Open Settings → Phone → Silence Unknown Callers and toggle it ON. Anyone not in your Contacts, Recents, or Siri Suggestions will go straight to voicemail. For carrier-level blocking, layer T-Mobile Scam Shield (dial #662#), AT&T ActiveArmor, or Verizon Call Filter on top.

How do I stop Scam Likely calls on Android?

Open the Phone by Google app → three-dot menu → Settings → Spam and Call Screen, then enable Filter spam calls. On Pixel, also enable Call Screen with Spam set to Automatically screen, decline, silently decline. On Samsung, use Phone → Settings → Block numbers → Caller ID and spam protection.

Does *#662# actually block scam calls?

Dialing #662# on T-Mobile turns on Scam Block, which silently rejects calls T-Mobile has classified as scam — they never ring your phone and never reach voicemail. Confirm with #787# and turn off with #632#. It's free and works without the app.

Why am I still getting Scam Likely calls after blocking?

Carrier filters miss new spoofed numbers for the first few hours of a campaign. Stack defenses: enable carrier scam blocking AND iOS Silence Unknown Callers / Android spam filtering AND a third-party app like Hiya or RoboKiller. Never press 1 or call back — both confirm your line is live.

Can I block Scam Likely calls without an app?

Yes. On T-Mobile dial #662#. On iPhone use Settings → Phone → Silence Unknown Callers. On Android use the Phone by Google built-in spam filter. None of these require a separate app download or a paid subscription.

Will blocking Scam Likely block legitimate unknown callers?

Carrier Scam Block only blocks calls flagged as fraud, so legitimate unknown numbers still ring. iOS Silence Unknown Callers and Android spam filtering are stricter — they send any unknown number to voicemail, which can miss doctor offices or delivery drivers. Check voicemail and Recents after the first few days to whitelist anyone important.
