This is a very cool project, happy to see the costs of this stuff coming down a little bit.
When I was an intern 15 years ago I worked on a software library for this https://www.embeddedts.com/products/TS-IRIDIUM Board that does a similar thing (though you would need to stack on a cellular board if you wanted cell modems).
We used them to help Arizona Department of Transportation collect traffic data in remote locations.
We had big plans at that company to make a much smaller, much cheaper 9602 transceiver replacement, but the company got bought out before that could launch.
