goTenna is a small, rugged device designed to make "No Service", no problem.
Just pair your smartphone with a goTenna and communicate off-grid with those near you who also have a goTenna, anywhere on the planet, regardless of access to cell reception or wi-fi. goTenna allows you to send and receive texts and share GPS locations on beautiful offline maps, without ever relying on central connectivity.
Depend on it in all kinds of situations: when hiking in remote areas, traveling abroad, attending music or sporting events or during an emergency. Plus, because goTenna is end-to-end encrypted, goTenna is not just for when you're off-grid, but when you want to be.
