Looks like your modem has a newer / different firmware.  in =

plugins/huawei.c, line:
                 gc =3D ofono_gprs_context_create(modem, 0,
                                                 "atmodem", data->modem);

Can you try changing "atmodem" to "huaweimodem" and see if it works =

after that?

Regards,
-Denis
