From my experience, my #Android devices require numerous #Google libraries in order to function properly with #GoogleFi, my current carrier. However, I swapped the physical SIM into my #Librem5 (#GNU #Linux, not Android) and calls, SMS, and mobile data worked out of the box. Great job, @purism!!
Next, I'd love to migrate to a Librem mobile plan once it's possible to transfer my existing number. 😊
@kop316 @purism This is my understanding as well (and same here - things may have changed in the last several years since learning this 😄).
I do recall, though, that GoogleFi mobile data did not work on my Pixel 2 with LineageOS VANILLA until I installed GAPPS. microG may also suffice, but I did not test this. I've heard that others have been able to access mobile data on other carriers using only VANILLA, which was the premise of my surprise.
@jc @purism look at JMP.chat and https://jmp.chat/sim for a free software backed experience that may be close

IIRC, GoogleFi defaults to one of the networks it uses without anything special. Most of the "special" libraries allow it to hop between carriers and WiFi (but this info is a few years ago, so things may be a bit different now).
