Happened to my Iridium satellite messenger (for peace of mind when hiking) too... Fortunately, there are several consumer/civilian alternatives to these.

I guess anything that's useful to regular hikers is potentially also useful to the armed, abroad type of hiker, and these are usually better funded, so I can see why startups like these would pivot.

It's unfortunate, GoTenna was (still is) pretty cool. Beartooth is similar and you can just buy them, but they unfortunately still have military-level pricing for what is pretty simple hardware.

Though in their defense, I'm not sure GoTenna was ever "popular." Probably not enough to pay the bills, given their pivot.
