Thank you! The following lines seemed to get me a step further:

ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0063", SUBSYSTEM=="usb", KERNEL=="cdc-wdm*", ENV{ID_MM_PORT_IGNORE}="1"
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0063", SUBSYSTEM=="usbmisc", KERNEL=="cdc-wdm*", ENV{ID_MM_PORT_IGNORE}="1"
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0063", SUBSYSTEM=="net", ENV{ID_MM_PORT_IGNORE}="1"

Now enabling does not lead to an error message anymore, but the modem
still seems to have problems, as it remains in the "searching" state:

[modem0] state changed (disabled -> enabling)
[modem0] power state updated: on
[modem0] 3GPP registration state changed (unknown -> searching)
[modem0] state changed (enabling -> searching)

Btw. my device is, according to lsub:

Bus 001 Device 004: ID 19d2:0063 ZTE WCDMA Technologies MSM K3565-Z HSDPA
