Yes, you can call things on ofono, if your app is unconfined. Use QtDBus
for that, or, depending on what you need, just execute the before
mentioned scripts from your app.

All of them are "available" in a sense that you can use them from a code
point of view, however, some of them might be restricted by apparmor
(again, need to be unconfined to use them) and some of them are also not
preinstalled in the sdk and you'd need to manually install them in your

I use the Ubuntu SDK yes... That said, so far I haven't written anything
that interferes with GSM functionality yet...
