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
That wouldn't surprise me. AOSP likely has enough hooks to know you are on a Google Fi SIM, but not the stuff needed to do anything useful until GAPPS is installed.
(I used Google Fi for a long time until I devested entirely from Google.)
