Thank you for using Apple Support Communities. It sounds like you're experiencing issues with blocked numbers on your device.

First, you'll want to make sure you install any pending updates available for your iPhone. Keeping your device fully updated can help resolve various issues and help with overall performance. Just in case, the resources below can help you:
