GoKawiilApple and Google's built-in tools now rival Truecaller for blocking spam calls
iPhone and Android devices include native spam-call filtering that can replace third-party apps like Truecaller. On iPhone, users can enable Call Filtering under Settings > Apps > Phone to send carrier-flagged junk calls to voicemail, separate Unknown Callers into their own list, and choose how to handle unrecognized numbers via the Screen Unknown Callers settings, including an option that asks callers to state their reason before the phone rings through.
GoKawiil's interpretation of the reporting above, not reported fact.
As spam-blocking matures into a standard OS feature, it reduces the need for paid third-party apps that previously filled this gap, potentially cutting into their subscription revenue. Carriers also offer their own spam protection, meaning users may have overlapping tools available without realizing it, so checking both phone and carrier settings could meaningfully reduce nuisance calls.
- iPhone's Call Filtering, found in Settings > Apps > Phone, can send carrier-flagged spam calls directly to voicemail.
- The Screen Unknown Callers feature offers a middle-ground 'Ask Reason for Calling' option that shows a live transcript before you answer.
- Carriers may provide their own spam protection, sometimes requiring manual activation via their app or online account.
