Any details on the technology? "Beaming phone signals" doesn't tell anyone much. Would this require a proprietary antenna (thus new, flagship-only models after a few years, like iPhone 15 with its emergency satellite calls) for whatever protocol Starlink uses (unless there is some unified ground-to-satellite protocol by now)?
Satellite phones aren't new, but are expensive for obvious reasons.
Starlink sats have enough transmit power and receive gain to use normal cellular frequencies with a normal antenna on the phone side.
You might think it's a long way to space, but a few hundred kilometres of direct line of sight to your cellphone antenna isn't that much more to overcome compared to say, 25 km to a cell tower on the ground.
The biggest hurdle was getting a few thousand satellites into orbit so that coverage and availability is there.
