I am not sure if the device should be using the option usbserial drivers or not.
Although I can assign wwan0 interface an IP address I somehow cannot connect to anywhere in
the world. So, I have to assign an IP back to ppp0 interface to get on the network.
I would hope I do have to provide the gprs username and password for the wwan0
interface as they are the defaults I think on the SIM card already. Googling around for some
manual how to configure wwan connection did not help much yet. Everything leads to to wvdial
and other and looks all is PPP-based stuff, actually.
Thanks,
Martin
