Comment 24 for bug 269329

It seems using gnome-ppp or kppp directly is the only option in Intrepid.

For gnome-ppp, see:

The "dialup" support in NM was simply a menu shortcut for the distro
native scripts to ifup / ifdown the connection, and was in no way
integrated into NetworkManager itself. Hence one of *the* most
requested features was for integrated 3G support so that people could
use the NM VPN plugins with mobile broadband."
