Message filtering not working

Check that SmishAlert is enabled and selected in iOS Settings.

If messages don't seem to be filtered, confirm the following:

  • Settings → Apps → Messages → Unknown & Spam: turn on Filter Unknown Senders, then select SmishAlert under SMS Filtering. On older iOS: Settings → Messages → Unknown & Spam → Text Message Filtering.
  • You are signed in. Personal includes on-device filtering at no charge. Unknown-sender screening requires Unknown Guard.
  • The message is from an unknown sender (iOS only filters unknown senders through the filter extension).
  • Restart the Messages app, or restart your iPhone, and try again.

If it still doesn't work, open the SmishAlert app and check for any in-app messages about subscription or permissions. For more help, use the chat on this site or contact support@smishalert.ai.
