  • Enable in iOS
    SMS filters are enabled from iOS Settings in the Messages section. Apple controls this permission and may ask you to confirm that you want to use NoCall as the filter for unknown senders or unwanted messages.

  • How NoCall decides
    NoCall can use sender-number signals and local rules to classify suspicious messages. Exact options depend on the app version and the permissions enabled on the device.

  • Privacy and control
    Review filter settings in the app from time to time. If a message is classified incorrectly, adjust your preferences or report the number to improve the community database.
