Telit LE910 failing to find network

Thanks a lot, the full syslog is here: https://pastebin.com/6X5K0gXU

Bus 001 Device 076: ID 1bc7:1201 Telit
Bus 001 Device 075: ID 1bc7:1201 Telit

They are both LE910s, the one I'm using (ttyUSB3 in the above syslog) is an
LE910 EUG (Euro / Aus). The other which I don't have a SIM card in is an
LE910 SVG (North America).

Perhaps missing support from the kernel? Here are the CDC-related ones:

grep CDC .config
CONFIG_USB_NET_CDCETHER=y
# CONFIG_USB_NET_CDC_EEM is not set
CONFIG_USB_NET_CDC_NCM=y
# CONFIG_USB_NET_CDC_MBIM is not set
CONFIG_USB_NET_CDC_SUBSET=y
# CONFIG_DRM_TILCDC is not set
# CONFIG_USB_CDC_COMPOSITE is not set

Also QMI-related:
grep QMI .config
# CONFIG_MSM_TEST_QMI_CLIENT is not set
CONFIG_USB_NET_QMI_WWAN=y
CONFIG_MSM_QMI_INTERFACE=y
# CONFIG_MEM_SHARE_QMI_SERVICE is not set
CONFIG_QMI_ENCDEC=y
# CONFIG_QMI_ENCDEC_DEBUG is not set

Many thanks for any hints,
Kelvin.
