Partially. 5G ZTE modems often use RNDIS + AT over MBIM. The AT command interface may appear as "ZTE Mobile Broadband Device" under Network adapters, not COM ports.

In the vast, humming ecosystem of embedded systems, few tasks feel as deceptively simple—or as maddeningly complex—as writing a driver for a ZTE cellular module via its AT interface. On the surface, it’s a serial port. A few wires, a baud rate, and the venerable "AT" command, a relic from the Hayes modem era of the 1980s. You might expect a quiet, predictable conversation. Instead, developing this driver is like trying to tame a chimera: part obedient terminal, part erratic network beast, and part silent, power-saving ghost.
Sometimes, updating the driver alone isn't enough. The device may need to be switched to a specific mode via direct AT commands. This is common with ZTE USB modems that initially mount as a virtual CD-ROM to run installation software.
Be aware that the "Connection Manager" monitors the modem port. If it detects commands, it may reset the modem. Avoid loading the Connection Manager while the USB modem is inserted when making these changes.
