Post install administration
Once the install is confirmed the FM 3xxx OBC will use the external LTE modem for all its communication
going forward. The firmware does not implement any fallback to 2G/3G by switching back to the internal
modem if the OBC it is out of LTE coverage. There is therefore no point in keeping the original internal SIM
active. The original SIM can be deactivated using the details captured for the asset prior to installing the LTE
External modem.
