It means that you can’t turn off Call Forwarding, probably because your carrier doesn’t support that switch. Or, if it really is a 5C, which cannot make calls on any network since 2023, it cannot connect to the carrier’s network to request setting deactivation. You can call the carrier, but but that will still not allow you to make calls using a 5C.
