Hi there,
Apologies - it is not very clear in the repo. but the code assumes that you have the "Board" set to the Adafruit Feather M0. You can find better instructions in the Iridium_9603N_Beacon repo.:
https://github.com/PaulZC/Iridium_9603_Beacon/blob/master/LEARN.md#how-do-i-upload-the-arduino-code
Please check that you have the Arduino SAMD (32-bits ARM Cortex-M0+) Boards and the Adafruit SAMD (32-bits ARM Cortex-M0+ and Cortex-M4) Boards installed. Then set the board type to Adafruit Feather M0.
Have fun!
Paul

You are welcome!
I must confess, this particular project is a little bit experimental. I have only assembled and tested two boards so far. They both seem to work OK but I would not call this project "fully tried and tested". The full Iridium Beacon has proved very reliable, so this one should be fine too. This design is really just an experiment to see how small I can make the beacon.
Closing this as your issue seems resolved. Please re-open if you have more problems.
All the best.
