On Mojave the installer complains about an expired certificate but continues.
Those from Huawei are still called DatacardDriverMacOSX(10.9) Upgraded from Yosemite the drivers work in Sierra. This is for the latest drivers from a Huawei installer I archived. The problem is now, that the old drivers can be shoehorned into a Sierra install but lead to a kernel panic on boot. On their support pages the now simply state and answer likewise to questions about it that they just do not offer that any longer. That also contained updated drivers that worked with more modern versions of the OS.
My mobile phone provider also used to offer their own bundle under the name 'Mobile Connection Manager'. Huawei used to offer upgrades that worked under OS 10.9 and another under 10.10 That however is now gone completely from the Huawei website and older links are either 404 or greeting us with the message 'Content has been archived'. These are hopelessly outdated and ceased to function with Mac OS X 10.9 Mavericks. Using a Huawei USB-stick for LTE connectivity there is a data-partition on the stick that automounts and offers the installation of a 'Mobile Partner.app' software and some drivers in the form of kernel extensions.
