ZTE MF190K AT Port (COM3) Driver

The ZTE MF190K AT Port (COM3) driver helps Windows recognize the modem’s AT-command interface, allowing compatible software to communicate with the connected ZTE USB device. It is intended for users setting up an MF190K modem, restoring a missing serial port, or troubleshooting an unrecognized device in Device Manager.

Key Features

• AT-command communication: Provides access to the modem’s control interface so compatible applications can send commands and read device responses.
• Serial port recognition: Enables Windows to identify the AT port as a COM interface. Although the device name includes COM3, Windows may assign a different port number depending on your system.
• Support for older Windows systems: Listed operating systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Choose a package that matches your Windows version and 32-bit or 64-bit architecture.
• Modem software integration: Helps connection managers and diagnostic tools access the AT interface. Separate drivers may be required for other modem functions, such as data connectivity.

How to Install ZTE MF190K AT Port (COM3) Driver

1. Check your system and device. Confirm your Windows version and architecture, then connect the modem directly to an available USB port. In Device Manager, look for the ZTE AT port or an unidentified device.
2. Choose a compatible package. Before starting a ZTE MF190K AT Port (COM3) driver download for Windows, verify the package’s supported operating systems and device identifiers. For Windows 10/11 setups, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed here.
3. Download and extract the files. Use a trusted source for a free download, and check that the package contains the appropriate driver files or installer. Avoid unrelated download utilities.
4. Install the driver. Run the included setup program, if available. Alternatively, right-click the device in Device Manager, select Update driver, and browse to the extracted folder. Follow the prompts.
5. Verify detection. Restart if requested, then check Device Manager for the AT port without a warning icon. Select its assigned COM number in your modem software if needed.

Keep the driver package available for future reinstalls. Before you update, compare the installed driver with the latest version offered for your exact device and operating system. A newer release may help resolve compatibility issues, but a stable, working installation does not always need replacing.
