Mobile Connect - PC UI Interface (COM5) Driver

The Mobile Connect – PC UI Interface (COM5) driver helps Windows recognize the PC UI serial interface exposed by compatible Huawei mobile broadband devices. You may need it if your Huawei modem appears as an unknown device, shows a warning in Device Manager, or cannot communicate with its connection-management software. Although listed under Network drivers, this component handles a communication interface rather than acting as the entire mobile broadband driver package.

Key Features

• Enables communication with the Huawei PC UI interface used by compatible modem software for device management and control.
• Helps Windows identify the interface under Ports (COM & LPT) in Device Manager; the assigned COM number can vary between computers.
• Works alongside other Huawei modem components needed for mobile broadband operation, depending on your device.
• Offers driver support for Windows 10, 8.1, 7, Vista, and XP when you select a package compatible with your hardware and Windows edition.

How to Install Mobile Connect – PC UI Interface (COM5) Driver

1. Identify your Huawei device model and Windows version. Check whether your system uses a 32-bit or 64-bit edition before choosing a package.
2. Select the Mobile Connect – PC UI Interface (COM5) driver download for Windows that matches your device and operating system. If choosing a free download, use a trusted source and verify the publisher and compatibility information.
3. Extract the downloaded archive if necessary. If the package includes an installer, run it and follow its instructions, including any prompts to connect or disconnect the modem.
4. For manual installation, open Device Manager, locate the affected Huawei interface or unknown device, and choose Update driver. Browse to the extracted driver folder and let Windows install the matching driver.
5. Restart if prompted, reconnect the device, and check Device Manager for warnings. Test your Huawei connection software to confirm that it recognizes the modem.

Keep this driver updated when a compatible release addresses detection problems or improves reliability. Choose the latest version validated for your specific hardware—not simply the newest package available. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed here, but Windows 11 support is not confirmed. Before an update, retain a working installer or create a restore point so you can recover if needed.
