Not sure if this is useful to off-gridders but I guess if you are in an area with voice towers that do not offer data, this could be useful.

I wonder if a software fax app on a GSM phone would be able to send faxes without needing data service. Or in fact, might it have to? Otherwise I guess if it were to use mobile data it would have to run over VOIP, perhaps with sketchier results.

    I suspect you might run into issues with the voice data-compression used by modern cellular networks.

      If that’s a lossy compression, then yeah that would surely blow the fax over voice GSM option. Although in principle a well-designed system would detect the fax/modem handshake and disable compression.
