HUAWEI Mobile Connect - 3G PC UI Interface (COM28) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM28) driver helps Windows recognize the serial communication interface exposed by a compatible Huawei mobile broadband modem. It enables supported Huawei connection software to communicate with the device and is useful when setting up a modem, restoring a missing interface, or resolving a driver warning in Device Manager.

Key Features

• Device communication: Provides the PC UI interface used by compatible software to exchange control and status information with a Huawei mobile broadband device.
• COM port recognition: Allows Windows to identify the interface as a serial port. COM28 is the assigned port number on this system; another computer may assign a different number.
• Legacy Windows support: Intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP. Check the individual driver package for your operating system and 32-bit or 64-bit architecture.
• Connection software integration: Helps compatible modem-management tools detect the interface. Mobile data access may also require other Huawei modem drivers, connection settings, and an active SIM.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM28) Driver

1. Check your hardware and Windows version. Open Device Manager and locate the Huawei interface under Ports (COM & LPT), Modems, or Other devices. If necessary, compare its hardware IDs with those supported by the package.
2. Choose a compatible package. Before starting your HUAWEI Mobile Connect – 3G PC UI Interface (COM28) driver download for Windows, confirm that the package matches your modem model and system architecture. Select the latest version that explicitly supports your configuration, not simply the newest available release.
3. Download and extract the files. Use a trusted manufacturer or verified distribution source. A free download should not require purchasing an unrelated driver-update utility.
4. Install the driver. Run the supplied installer, or right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts and do not bypass driver-signature warnings.
5. Reconnect and verify. Restart Windows if requested, reconnect the modem, and confirm that the interface appears without a warning icon. Check that your connection software uses the assigned COM port.

Keep the driver updated when a compatible release addresses a problem or improves device support. For Windows 10/11 systems, verify compatibility separately: Windows 10 support does not establish Windows 11 support. If an update causes issues, use Device Manager’s Roll Back Driver option when available.
