ZTE CDMA Handset NMEA Interface (COM4) Driver

The ZTE CDMA Handset NMEA Interface (COM4) driver helps Windows recognize the NMEA communication interface exposed by a compatible ZTE CDMA handset over USB. It is intended for users who need software to access handset-provided NMEA data, typically associated with positioning, or who need to resolve a missing driver for this interface in Device Manager.

Key Features

• Enables communication between Windows and the handset’s NMEA interface through a virtual serial port.
• Allows compatible applications to access NMEA data when the handset and its firmware support that functionality.
• Helps Windows identify the interface correctly rather than displaying it as an unknown device or an interface with a driver warning.
• Intended for supported Windows 10, 8.1, 7, Vista, and XP systems, provided the selected package matches your handset and Windows architecture.

How to Install ZTE CDMA Handset NMEA Interface (COM4) Driver

1. Confirm the device and operating system. Connect the handset using a data-capable USB cable, then open Device Manager. Check the interface’s hardware IDs under Properties > Details and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your ZTE CDMA Handset NMEA Interface (COM4) driver download for Windows, verify that the package supports your hardware IDs and Windows edition. Choose the latest version that explicitly supports your device, not simply the newest available file.
3. Download and prepare the files. Use a trusted source for a free download, scan the package with your security software, and extract it if it is compressed.
4. Install the driver. Run the included installer, if available. Alternatively, right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts and restart if requested.
5. Check the connection. Confirm that the interface appears without a warning icon, then select its assigned COM port in your compatible application. Windows may assign a port other than COM4; use the port shown in Device Manager.

Keep the driver updated when a verified, compatible release addresses connection problems or improves stability. For Windows 10/11 users, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here. Before any update, check the package requirements and retain a working driver so you can roll back if necessary.
