ZTE Mobile Broadband NMEA Port (COM73) Driver

The ZTE Mobile Broadband NMEA Port (COM73) 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 unrecognized NMEA port in Device Manager or whose compatible software needs access to navigation data, where supported by the hardware and firmware.

Key Features

• NMEA interface recognition: Allows Windows to identify the device’s dedicated NMEA port rather than leaving it listed as an unknown device.
• Serial communication support: Provides a COM-port connection that compatible applications can use to receive NMEA data when the modem supports this function.
• USB broadband device integration: Supports one interface within a ZTE mobile broadband device; separate drivers may be required for modem, network, or diagnostic functions.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your specific device and Windows architecture.

How to Install ZTE Mobile Broadband NMEA Port (COM73) Driver

1. Identify your hardware and system. Open Device Manager, locate the ZTE NMEA interface, and check its hardware IDs under Properties > Details. Confirm your Windows version and whether it is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your ZTE Mobile Broadband NMEA Port (COM73) driver download for Windows, verify the supported hardware IDs and operating systems. Look for the latest version validated for your modem through ZTE or your device supplier, and use a trusted free download source.
3. Prepare the files. Extract the downloaded archive if necessary. If replacing an existing driver, consider creating a restore point before you install the update.
4. Run the installer or use Device Manager. Follow the package’s setup instructions. For a driver-only package, right-click the device, select Update Driver, and browse to the extracted folder.
5. Verify the connection. Restart if prompted, then check Device Manager for warning icons. The assigned COM number can change, so configure your application to use the port currently shown rather than assuming it remains COM73.

Keep the driver updated when a compatible release addresses connection or recognition problems. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed here. A newer package is useful only if it matches your hardware and operating system.
