I have an iridium sat phone. It is really bad, just better than nothing. So if globalstar is worse: sheesh.
Anyway we should all be going starlink.
Globalstar is cheaper but significatly worse. Starlink will change the game and reduce them to SOS communications only. Yatchts, jets and RVs will all switch to StarLink as their primary connectivity channel, except when docked, then LTE/5G makes more sense in some cases.
