ZTE Mobile Broadband NMEA Port (COM9) Driver

The ZTE Mobile Broadband NMEA Port (COM9) driver helps Windows recognize the NMEA serial interface exposed by compatible ZTE USB mobile broadband devices. It is intended for users whose modem shows an unidentified port in Device Manager or whose compatible positioning software needs access to NMEA data, where supported by the hardware.

Key Features

• NMEA interface recognition: Allows Windows to identify the device’s NMEA port, which can carry positioning-related data on supported ZTE hardware.
• Serial communication support: Provides a COM-port connection that compatible applications can use to communicate with the NMEA interface.
• USB device integration: Supports one interface within a ZTE mobile broadband device. Separate drivers may be required for its modem, network, or diagnostic functions.
• Legacy Windows compatibility: Driver packages for this device are listed for Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.

How to Install ZTE Mobile Broadband NMEA Port (COM9) Driver

1. Check your device and Windows version. Open Device Manager and locate the ZTE port or unidentified USB device. Check its hardware IDs under Properties > Details to help confirm the correct package. For Windows 10/11 systems, note that Windows 11 is not included in the listed supported operating systems; verify compatibility before proceeding.
2. Select the appropriate package. Before starting your ZTE Mobile Broadband NMEA Port (COM9) driver download for Windows, confirm that the package matches your device, operating system, and 32-bit or 64-bit architecture. Choose the latest version verified for that combination rather than simply the newest available package.
3. Download and extract the files. If a free download is offered, check its source and publisher before opening it. Extract compressed files to a folder you can easily find.
4. Install the driver. Run the supplied installer, if included, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts.
5. Verify the connection. Restart Windows if requested, then check that the port appears without a warning icon. Windows may assign a number other than COM9; select the actual assigned port in your application.

Keep the driver updated when a compatible release addresses a connection issue or improves support for your Windows installation. Before an update, retain the working installer or create a restore point so you can recover if the new driver causes problems.
