Known issues
"QMI_UIM_CARD_STATE_ERROR"
You may encounter this error when issuing the "diagnose sys sim-info" command on 30E-GBL devices. This is
because the SIM card slot in the device has a design defect, which sometimes could cause the SIM card to be loosely
connected. The modem is unable to read from the card due to the loose contact.
Workaround:Usually you can solve the problem by using a good-quality SIMcard adapter, but you may file an RMA
request if the problem persists.
No location information for 30E-GBL
Even though FortiOS supports GPS function of the modem, the 30E-GBL units do not have GPS antenna equipped.
Therefore, it cannot receive GPS information even with the GPS daemon enabled.
“execute sys lte-modem” commands fail to work
This issue occurs when the following message is displayed:
This is usually caused by an unfinished configuration left in the system. It happens when FortiOS is in the mid of setting
an LTE configuration but gets interrupted. This leaves a lock to the interface in the daemon. As s result, any future
operation to the interface would be denied.
Workaround: Reboot the unit.
