HUAWEI Mobile Connect - 3G PC UI Interface (COM72) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM72) driver lets Windows recognize the PC UI serial interface exposed by compatible Huawei mobile broadband hardware. It supports communication between the device and compatible connection-management software, making it useful when setting up a Huawei modem or troubleshooting an unrecognized COM port.

Key Features

• Serial interface recognition: Helps Windows identify the Huawei PC UI interface and make it available to applications that communicate through a COM port.
• Connection software support: Enables compatible Huawei utilities to exchange control and status information with the device. This interface is one component of the modem setup, rather than a standalone internet connection driver.
• Legacy Windows compatibility: Intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP, subject to the individual driver package’s requirements.
• Device identification: Helps resolve missing-driver warnings when the package matches your hardware. COM72 is a Windows-assigned port number and may differ after reinstalling or moving the device.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM72) Driver

1. Check your device and system. Open Device Manager, locate the Huawei interface, and review its hardware IDs under Properties > Details. Confirm your Windows version and whether it is 32-bit or 64-bit.
2. Choose a matching package. Before starting a HUAWEI Mobile Connect – 3G PC UI Interface (COM72) driver download for Windows, verify the supported hardware and operating systems. For Windows 10/11 searches, note that Windows 11 is not listed among the supported systems here.
3. Download and extract the files. Use a trusted source for a free download, and check that the latest version offered actually supports your device and Windows edition.
4. Install the driver. Run the included setup program, if provided. Alternatively, right-click the interface in Device Manager, select the driver update option, and browse to the extracted driver folder.
5. Verify the result. Restart Windows if prompted, reconnect the device, and check Device Manager for warning icons. If your application requires a specific port, confirm the currently assigned COM number.

Keep the driver updated when a compatible release addresses a problem or improves support for your setup. Before an update, retain a working installer or create a restore point so you can recover if the new package causes issues.
