HUAWEI Mobile Connect - 3G PC UI Interface (COM15) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM15) driver helps Windows recognize the serial control interface exposed by compatible Huawei mobile broadband hardware. It is intended for users whose Huawei modem appears as an unknown device, shows a warning in Device Manager, or cannot communicate properly with compatible connection-management software. Although associated with network hardware, this interface handles device communication rather than acting as the mobile data connection itself.

Key Features

• Serial interface recognition: Enables Windows and compatible software to identify and access the Huawei PC UI interface through an assigned COM port.
• Device-management communication: Supports communication between the modem and applications used to manage compatible Huawei mobile broadband devices.
• Legacy Windows support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP; the correct package depends on your hardware and Windows architecture.
• Troubleshooting support: Installing a matching driver may resolve missing-driver warnings or interface detection problems. The COM15 designation is a Windows port assignment and may change after reconnection or reinstallation.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM15) Driver

1. Check your device and operating system. Open Device Manager and locate the Huawei interface, which may appear under Ports (COM & LPT) or Other devices. Check its hardware IDs and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – 3G PC UI Interface (COM15) driver download for Windows, verify that the package matches your hardware IDs and operating system. Choose a trusted free download, preferably from Huawei or your device supplier.
3. Install the driver. Extract the downloaded archive if needed. Run the supplied installer, or select Update driver in Device Manager and browse to the extracted driver folder.
4. Reconnect and verify. Follow any restart prompts, reconnect the modem, and confirm that the interface appears without a warning icon. If your application requires a COM port, select the port currently assigned by Windows.
5. Check compatibility if problems persist. For Windows 10/11 systems, verify support explicitly: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed. Avoid forcing an incompatible package.

Keep the driver updated when a compatible release addresses a problem or improves support for your setup. The latest version is useful only if it matches your device and operating system; before an update, retain a working installer or create a restore point so you can recover if necessary.
