A phone plugged on the power of the car, but not on its roof antenna, and with windows closed - one should worry about strong EM waves and health in a first place. Besides, such an in-car phone might have little chance to talk up to satcom 5G direct-to-cell (direct-to-smartphone, -to-device, 'D2D' but not 'device-to-device'; care about these terms, they are wrongly used and abundantly these days, probably because it's at the beginning). Similarly, in-_plane_ smartphones might have similar problems to talk up(?) to satcom 5G. It might work, maybe very badly, maybe with very low bandwidth and high latencies, if at all. The frequency range around 800MHz (and not 1GHz-3.5GHz) has been mentioned for direct-to-cell.   This frequency set was often touted advantageously for car 4G communications but it has not really been used.  Maybe it'll be re-proposed for satcom 5G NTN, because it is little occupied but present in many smartphones.
