I think the app figures out where you are based on GPS co-ords and lets you fly or not. That's what my mavic mini appears to do when I fly it with no internet connection. It will even pop up warnings like "airport flight restriction nearby" and it does that with no internet...

Yeah it has internal GPS, works without WiFi and SIM and sets automatic height restrictions based on where you are. I live in Brooklyn near an LGA approach vector, surprisingly it tells me the maximum height is 150m, which still feels pretty high considering how low jets pass over on their way to LGA.
