Qt uses QPA plugins to provide this information. On the desktop, I have 
a NetworkManager plugin:
/usr/lib/x86_64-linux-gnu/qt5/plugins/bearer/libqnmbearer.so

I can't access my Ubuntu phone right now, but please check if you have a 
libqnmbearer.so in the directory returned by "qmake -query 
QT_INSTALL_PLUGINS".

Then you could check with "strace" if that plugin is ever loaded. If 
not, I'm not sure what's to be done. You could try playing with the 
QT_QPA_GENERIC_PLUGINS environment variable (I just found it searching 
in the Qt source code), to see if you can force it loading.

Ciao,
