We’re all for big adventures that take us off the grid, but it’s never a bad idea to have a way of getting in touch. For organizing a pick up, initiating a rescue, or just checking in, a satellite messenger has become our go-to means of staying connected in areas without cell service. In addition to their ability to send (and—most of the time—receive) messages, these devices tack on a range of other functions, including location sharing, GPS navigation, weather reporting, and more. Our picks below represent a complete view of the market, ranging from high-powered hotspots that pair with your smartphone to simple one-way messengers.
