How to use Call Screening to block spam and unknown calls on iPhone

With iOS 26, iPhone users can activate Call Screening to manage unknown calls.

Updated on: Nov 3, 2025, 09:14:03 IST

iOS 26 introduced Call Screening, a new feature designed to filter calls from unknown numbers before users answer. The system automatically asks callers to state their name and reason for calling, then displays a real-time transcription on the iPhone screen. Users can then decide whether to pick up, ignore, or block the call. All processing happens on-device, keeping data private.

  • Silence: Sends unknown numbers directly to voicemail.

Selecting Ask Reason for Calling activates the feature immediately. From this point, any call from a number not in contacts or recent outgoing calls will go through the screening process.
