HUAWEI Mobile Connect - 3G PC UI Interface (COM5) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM5) driver allows Windows to recognize the PC UI communication port exposed by compatible Huawei mobile broadband hardware. It is intended for users whose Huawei modem or data card shows an unknown interface, a missing driver, or a warning icon in Device Manager.

Key Features

• PC UI interface recognition: Helps Windows identify the Huawei interface used by compatible connection-management or diagnostic software to communicate with the device.
• COM port access: Provides a serial communication interface shown here as COM5. Windows may assign a different COM number depending on your system and connected devices.
• Mobile broadband software support: Supports communication between compatible Huawei utilities and the hardware; it does not replace the separate modem or network drivers that some devices require.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP when the downloaded package matches your hardware and operating system architecture.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM5) Driver

1. Confirm the device details. Open Device Manager and locate the Huawei interface under Ports (COM & LPT) or Other devices. Check its hardware IDs in Properties > Details to help identify a matching package.
2. Choose a compatible download. Before selecting a HUAWEI Mobile Connect – 3G PC UI Interface (COM5) driver download for Windows, verify the supported OS, hardware IDs, and 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 11 is not included in the listed supported operating systems.
3. Prepare the files. Obtain the package from a trusted source and extract it if necessary. If offered as a free download, check that it contains the driver rather than an unrelated installer.
4. Install the driver. Run the supplied setup program, or 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 recognition. Reconnect the Huawei device and confirm that its PC UI interface appears without a warning icon. If your software requires a specific port, select the COM number currently shown in Device Manager.

Keep the driver updated when Huawei provides a compatible release that addresses your needs. Choose the latest version verified for your specific hardware and Windows release, rather than assuming every newer package will work. An update may resolve recognition or communication issues, but it will not necessarily improve mobile signal strength or connection speed.
