HUAWEI Mobile Connect - 3G PC UI Interface (COM30) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM30) driver helps Windows recognize the serial control interface used by compatible Huawei mobile broadband devices. It enables communication between the device and connection-management software, making it useful when setting up a Huawei modem or troubleshooting an unrecognized PC UI interface in Device Manager.

Key Features

• PC UI interface recognition: Allows Windows to identify the Huawei control interface instead of listing it as an unknown device.
• Serial communication support: Provides the COM-port connection that compatible Huawei software may use to manage or communicate with the modem.
• Legacy Windows compatibility: Intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP, with package compatibility dependent on your hardware and system architecture.
• Driver repair and replacement: Reinstalling or updating the correct package can help resolve missing-driver errors affecting this interface. Other modem functions may require separate driver components.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM30) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, inspect the interface’s hardware IDs to help match the driver to your Huawei hardware. COM30 is an assigned port number and may differ on another computer.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – 3G PC UI Interface (COM30) driver download for Windows, verify the supported operating systems and hardware IDs. Select the latest version that explicitly supports your device, rather than assuming every newer package will work.
3. Download and extract the files. Use a trusted source for a free download, scan the package with your security software, and extract it if necessary.
4. Install the driver. Run the supplied installer, if available. Alternatively, open Device Manager, right-click the affected interface, choose Update driver, and browse to the extracted driver folder. Follow the prompts.
5. Verify detection. Restart Windows if requested, reconnect the modem, and check that the interface appears without a warning icon. Test it with compatible Huawei connection software.

Keep the driver updated when a compatible release addresses a problem or improves support for your setup. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed here. Avoid forcing an unsupported update when your existing driver works reliably.
