To block "Scam Likely" calls on an iPhone, there are several effective methods:
- Enable "Silence Unknown Callers" in Settings > Phone. This sends calls from numbers not in Contacts, Recent calls, or Siri Suggestions directly to voicemail without ringing. These calls appear in Recents and voicemail if left messages. This method catches many scam calls but also silences all unknown numbers, so important unknown calls might be missed.
- Manually block specific scam numbers after receiving calls by going to the Recents tab in the Phone app, tapping the (i) info next to the number labeled "Scam Likely," then choosing "Block this Caller."
- Use "Call Blocking & Identification" features under Settings > Phone to enable carrier or third-party spam detection. Some carriers like Verizon or T-Mobile label scam calls and can silence them automatically.
- With iOS 26 and later, you can enable Call Screening under Settings > Phone > Screen Unknown Callers, choosing "Ask Reason for Calling" to filter unknown calls by requiring callers to state their purpose before your phone rings, or "Silence" to send unknown calls (including scams) straight to voicemail.
These features can be combined for better protection. Blocking individual numbers may have limited effect because scammers frequently change numbers, so enabling silencing or screening unknown callers is more effective to block scam likely calls on iPhone.
