When comparing satellite reception it's not so much if you can receive data or not, but at what bandwidth. By contrast, data rates for Starlink are roughly 50 to 100 megabits per second; a million times greater than GPS.
So that's why the Starlink dish and electronics are orders of magnitude larger than a phone. Or to put it another way, that's why mobile phones can handle GPS data but not Starlink data.
> Apple has created a mechanism that will ask users to be outdoors and walk in a certain direction to help the iPhone connect to a satellite. Linking to a network also won’t always be instantaneous, with testing of the feature indicating that it could sometimes take up to one minute to work.
