If a spam call rings to your phone and RoboKiller still reports that the call was blocked, there may be an issue with the iOS CallKit feature on your device. The CallKit feature is responsible for stopping calls from ringing to your iPhone. In this case, RoboKiller is correctly identifying calls as spam, however, the call is not being blocked by CallKit.

To resolve this, please make sure you are updated to the latest version of IOS and disable your device's WiFi. Also, please make sure RoboKiller is the only spam/call blocking app on your phone.

Then, go to Settings > Phone > Call Blocking & Identification on your iPhone. If you see any phone numbers listed, please make sure all of them have country codes at the beginning of them (+1 for the US and Canada). Also, make sure any names, email addresses, or incomplete phone numbers are removed from the list as well.

Then, turn both RoboKiller switches OFF and follow these steps:

1. Uninstall the app from your phone
2. Reboot your phone
3. Reinstall the app (do NOT open the app yet)
4. Go straight to Settings > Phone > Call Blocking & Identification on your iPhone
5. Turn both switches ON for RoboKiller.

After this, please go back into the RoboKiller app, and go through the prompted set-up in the app to return to your account.
