Hi,

SWI9X30C_02.08.02.00 r5428 CARMD-EV-FRMWR2 2016/01/06 20:38:53

defaults to qmi and some problems with two devices, raw-ip mode and other things. 
But it in the end it did work on my device.

defaults to mbim on my machine and works perfectly from the first second. (also ipv4/ipv6)

I:  If#=13 Alt= 1 #EPs= 2 Cls=0a(data ) Sub=00 Prot=02 Driver=cdc_mbim

So I would recommend to give the firmware update a chance.
