I have the same problem in Ubuntu 16.04 with an Huawei E122.
My workaround is to execute manually the switch using "Huawei newmode"
parameter:
/usr/sbin/usb_modeswitch --default-vendor 0x12d1 --default-product 0x1446 -J

Title:
usb_modeswitch@.service fails
Status in usb-modeswitch package in Ubuntu:
Fix Released
Bug description:
I lack the technical knowledge to know if this is a bug in udev,
systemd or another component.
After the switch to systemd, my 4G Huawei USB modem no longer
functions as a modem unless I run usb_modeswitch to flip its state
from USB mass storage. The command I issue and its output is below,
which also show the Vendor and Product ID.
Strangely, it does not do this every time. Yesterday when I updated
using apt-get dist-upgrade upon reboot the modem worked as expected.
But from a cold boot this morning it did not.
$ sudo usb_modeswitch -v 0x12d1 -p 0x1f01 -J
[sudo] password for damon:
