TCT Mobile Connect - 3G PC UI Interface (COM6) Driver

The TCT Mobile Connect – 3G PC UI Interface (COM6) driver helps Windows recognize the USB-connected Tct device’s PC UI interface as a serial communication port. It is intended for users whose compatible Tct mobile broadband hardware appears as an unknown device, shows a warning in Device Manager, or cannot communicate with its connection-management software.

Key Features

• USB interface recognition: Allows Windows to identify the device’s 3G PC UI interface rather than leaving it listed as an unrecognized USB component.
• Serial communication support: Provides the COM-port interface used by compatible software to communicate with the connected hardware. Although the device name includes COM6, Windows may assign a different port number.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows version and system architecture.
• Component-specific support: Addresses the PC UI interface; other functions of the same USB device may require separate drivers or compatible connection software.

How to Install TCT Mobile Connect – 3G PC UI Interface (COM6) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the device’s hardware IDs to help verify that the package matches your hardware.
2. Choose the correct package. Before starting your TCT Mobile Connect – 3G PC UI Interface (COM6) driver download for Windows, review its compatibility details. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed.
3. Download and extract the files. If a free download is available, use a trusted source and scan the package with your security software. Extract compressed files before proceeding.
4. Install the driver. Run the supplied installer, if included. Alternatively, open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder.
5. Verify detection. Reconnect the device or restart Windows if prompted. Check that the interface appears without a warning icon and that your compatible software uses the assigned COM port.

Keep the driver updated when a verified release addresses a connection issue or improves compatibility. Check for the latest version that explicitly supports your device and operating system rather than assuming every newer package will work. Before an update, retain the working installer or create a restore point so you have a recovery option.
