Yes, "Yikes" on the prices.
Not quite there, but getting close to the cost of a Sat Phone.
The InReach does work with your Smartphone, so no need for their GPS on top of the InReach, and I think the InReach will work "standalone".
If you look around you will find that a sat phone monthly plan (without cancelation penatly) is $30 for Inmarsat, and $40 for Iridium now. Now that you can just pay for a month and then add airtime if you actually need to use it, the cost of operating a sat phone part time has come down significantly.
