HUAWEI Mobile Connect - 3G PC UI Interface (COM24) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM24) driver allows Windows to recognize the PC UI serial interface exposed by a compatible Huawei mobile broadband device. It is intended for users whose Huawei modem appears as an unknown device, shows a driver error, or cannot communicate with compatible connection-management software.

Key Features

• Enables communication with the modem’s PC UI interface, which compatible software may use for device management and status information.
• Supports recognition of the interface as a virtual COM port in Device Manager. COM24 is the assigned port number, not a separate modem model, and may change after reconnecting the device.
• Helps resolve missing-driver issues affecting this interface. Other modem functions may require additional components from the Huawei driver package.
• Covers Windows 10, 8.1, 7, Vista, and XP when the downloaded package supports your specific hardware and Windows architecture.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM24) 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 (COM24) driver download for Windows, verify that the package matches those hardware IDs and your operating system. Choose a trusted free download, preferably from Huawei or your device supplier.
3. Extract and install. Unpack the download if necessary. Run the included installer, or right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
4. Reconnect and verify. Follow any restart instructions, then reconnect the modem. Check that its PC UI interface appears without a warning icon; Windows may assign a different COM number.
5. Test compatible software. Open your Huawei connection manager and check whether it detects the device. If it does not, verify that the package’s other required modem interfaces are installed.

Keep the driver updated when a compatible release addresses connection or recognition problems. The latest version should match your hardware—not simply have a newer label. For Windows 10/11 systems, check support separately: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Create a restore point before an update so you can recover if the new driver causes problems.
