call-failed using Huawei E398

[Kai Scharwies]

Hi.

I am trying to establish an UMTS connection using latest version
libqni and a E398 USB stick.
Kernel (3.5.2) detects the cdc interface correctly after calling usb_modeswitch.

My steps so far:

qmicli -d /dev/cdc-wdm0 --dms-uim-verify-pin=PIN,1234
[/dev/cdc-wdm0] PIN verified successfully

qmi-network /dev/cdc-wdm0 start
Starting network with 'qmicli -d /dev/cdc-wdm0 --wds-start-network
--client-no-release-cid'...
error: couldn't start network: QMI protocol error (14): 'call-failed'
call end reason: 1013
verbose call end reason: 6, 27
Saving state... (CID: 2)
error: network start failed, no packet data handle
Clearing state...

Sim card is from Vodafone and the APNs are configured as following:
at+cgdcont?
+CGDCONT: 1,"IP","web.vodafone.de","0.0.0.0",0,0
+CGDCONT: 16,"IP","web.vodafone.de","0.0.0.0",0,0

at+cops?
+COPS: 0,0,"Vodafone.de",2

Did I miss a step or is this Huawei modem not yet supported?

Best regards,
Kai
