If dhcp doesn't work after a successful AT^NDISDUP connection, then there is still a chance that this actuall is a NCM device. That would make things easier in many ways :-) Please try the huawei_cdc_ncm driver, although I am not completely sure that works at all at the moment. Snooping on the device in Windows is another option... Or the device might just not support DHCP. You could try the AT^DHCP? command after connecting, and then configure the wwan0 device manually using addresses from the output of that command.
