Pros Compact and lightweight ergonomic design, rental optionEasy and affordable two-way messaging, great smartphone app, feature loaded, proven global networkTwo-way messaging, on-device keyboardCOSPAS/SARSAT’s reliability and long track record, no annual fees, simple operationReasonable initial purchase price, no paid subscription, uses proven global network, compact
Cons No two-way communication, no smartphone interface, Globalstar is arguably less effective than Iridium or COSPAS/SARSATExpensive initial purchase, largest and heaviest messengerBulky, no smartphone interfaceLarger and heavier than closest competitorNo non-emergency messaging
Bottom Line The lowest up-front cost satellite messenger with a handy rental option.Fully featured and arguably more reliable even than commonly available satellite phones.A two-way texting device with a built-in keyboard reminiscent of old Blackberry phones with slightly limited geographic coverage.An excellent emergency-only (with one debatable caveat) personal beacon.Compact, affordable “help me” button in your pocket.
