To block all "scam likely" calls, use several methods depending on your phone type and carrier:
- On an iPhone, block individual scam numbers via the Phone app Recents list by tapping the (i) icon and selecting Block Caller. To prevent most unknown calls, enable Silence Unknown Callers in Settings > Phone.
- On Android phones, block numbers manually from the Phone app Recents, and activate built-in spam protection under Settings > Caller ID and spam protection to filter and warn about spam calls.
- Major carriers like AT&T, Verizon, and T-Mobile offer free or subscription services (e.g., AT&T ActiveArmor, Verizon Call Filter, T-Mobile Scam Shield) to detect and block scam calls at the network level.
- Third-party call-blocking apps can also filter scam calls based on community reports and databases.
- Dialing *#662# on some carriers activates "Scam Block" which can block scam likely calls automatically.
These combined approaches greatly reduce scam likely calls by blocking them on device and network levels and using advanced call filtering apps.
