Thread: Starlink vs PLB

Nope,
PLBs transmissions are routed direct to RCC (Rescue Coordination Center) the beacon is registered too.
They automatically transmit their current location when activated (modern ones do anyway) and also have a beacon built in that Aircraft can home in on once they are in the area.
Cellphones rely on information supplied by the user, have no homing beacon. Their batteries may also not last as used for other things.
I would consider them as a good addition to your safety equipment but not a replacement for a PLB
