HUAWEI Mobile Connect - 3G GPS Interface (COM3) Driver

The HUAWEI Mobile Connect – 3G GPS Interface (COM3) driver helps Windows recognize the GPS-related serial interface exposed by compatible Huawei mobile broadband hardware. It is intended for users setting up a supported Huawei device or troubleshooting an unrecognized GPS interface, a missing COM port, or a driver warning in Device Manager.

Key Features

• GPS interface recognition: Enables Windows to identify the Huawei GPS interface so compatible applications can communicate with it when the hardware and firmware support GPS functionality.
• Serial port access: Provides access through a virtual COM port. Although the device name includes COM3, Windows may assign a different port number depending on your system configuration.
• Windows compatibility: Supported operating systems listed for this device include Windows 10, 8.1, 7, Vista, and XP. The correct package must also match your hardware and Windows architecture.
• Driver troubleshooting: Installing a compatible package can help resolve missing-driver errors or restore interface detection after a system reinstall. This interface driver alone does not provide mobile internet service or navigation software.

How to Install HUAWEI Mobile Connect – 3G GPS Interface (COM3) Driver

1. Check your device details. Open Device Manager and locate the Huawei interface, usually under Ports (COM & LPT) or Other devices. Review its hardware IDs to confirm that the download matches your hardware.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – 3G GPS Interface (COM3) driver download for Windows, verify the supported operating system and whether your installation is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 11 support is not confirmed by the compatibility list above.
3. Download and prepare the files. Obtain the latest version compatible with your device from a trusted source, preferably Huawei or your hardware supplier. Check any free download for authenticity and extract the archive if necessary.
4. Install the driver. Run the supplied installer, or right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Verify recognition. Restart Windows if requested, reconnect the device, and check that the interface appears without a warning icon. Select its assigned COM port in your compatible GPS application if required.

Keep the driver updated when a verified, compatible update addresses a problem or improves compatibility. The latest version is not always suitable for older hardware, so prioritize an exact device match and retain a working installer for recovery.
