Is the APN correct?

If the APN is correct, as a quick hack try changing:

                 gc = ofono_gprs_context_create(modem, 0,
                                                 "atmodem", data->modem);

in plugins/huawei.c huawei_post_sim() to

                 gc = ofono_gprs_context_create(modem,
					OFONO_VENDOR_SIMCOM_SIM900,
                                         "atmodem", data->modem);
