HUAWEI Mobile Connect - 3G PC UI Interface (COM16) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM16) driver lets Windows recognize the PC UI communication interface exposed by compatible Huawei USB mobile broadband devices. You may need it if this interface appears as an unknown device in Device Manager, shows a warning icon, or cannot communicate with your connection-management software.

Key Features

• USB interface recognition: Helps Windows identify the Huawei PC UI interface as a serial communication port rather than an unrecognized USB component.
• Device-management communication: Enables compatible Huawei software to exchange control and status information with the connected device. This interface is one part of the device’s driver setup, not a standalone internet connection.
• Legacy Windows support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP; check the individual package for its exact operating-system and architecture requirements.
• COM port identification: Makes the interface accessible through its assigned port. COM16 is a Windows-assigned identifier and may change when the device is reconnected or installed on another computer.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM16) Driver

1. Check your device and Windows edition. Open Device Manager, locate the Huawei interface, and review its hardware IDs under Properties > Details. Confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a matching package. Before starting a HUAWEI Mobile Connect – 3G PC UI Interface (COM16) driver download for Windows, verify that the package supports your hardware and OS. If comparing Windows 10/11 options, note that Windows 11 compatibility is not confirmed by the supported OS list here.
3. Download and extract the files. Prefer a trusted Huawei or device-provider source. A free download should not require third-party driver-updater software; check that the package is intended for your device.
4. Install the driver. Run the included setup program, if available. Alternatively, right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Reconnect and verify. Restart if prompted, reconnect the device, and check that the interface appears without a warning icon. Confirm the assigned COM port in your compatible management software.

Keep the driver updated when a verified release addresses a connection problem or supports your Windows configuration. Choose the latest version compatible with your specific hardware—not simply the newest package—and retain a working installer in case you need to roll back an update.
