Some impressing work is indeed being done here on the PinePhone modem: https://github.com/Biktorgj/pinephone_modem_sdk/ https://github.com/Biktorgj/pinephone_modem_sdk/ (firmware replacement, with a re implementation of many blobs and a mainline linux kernel - I tried and everything seems to work, however the sound is a bit low by default (this can be configured) and the modem is slow to boot)
