The modem doesn't advertise CDC ACM interface/subinterface descriptors in its USB interfaces, so it's not surprising that it's not detected automaticaly. See bInterfaceClass and bInterfaceSubclass of both USB interfaces in the attached lsusb -vvv output (above).
The only way to handle these devices will probably be to explicitly list them by USB vendor and product id in a suitable USB serial driver, like option.c . I don't know whether the use of the option driver alone tells NM enough to treat the device as a GSM modem. If option can support CDMA devices too, then some sort of device probe or configuration hint might be needed.
