The main problem here is that we lack of a UI interface to read/send SMS. In ModemManager >=0.7.x, you can use mmcli to list, read, send SMS messages; but of course a command line interface is not a very friendly UI for everyone. I know that there is work ongoing in KDE to have an SMS messaging interface, and I know that Empathy in GNOME has some support for SMS (for oFono if I'm not mistaken). We just need someone to either plugin the MM Messaging interface in an already existing messaging application, or write a whole new application all together. I thought about writing an extension for GNOME Shell doing this, but never really started. Anyone interested in doing that? :) -- Aleksander _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
