Depends on where you are. In Canada, our system sends everything as "National/Presidential Alerts". We don't use the different levels at all. So AMBER Alert, Weather Alert, etc are all Presidential/National Alerts.
Canada doesn't have a president, but until it passes a law that requires phones sold in Canada to have Canada-specific features in the alert display, it will say what it says in the USA. And in USA the Presidential Alert is switching to National Alert.
