TCT Mobile Connect - 3G PC UI Interface (COM17) Driver

The TCT Mobile Connect – 3G PC UI Interface (COM17) driver helps Windows recognize the USB-connected Tct device’s PC interface and allows compatible software to communicate with it through a virtual serial port. You may need this driver if the interface appears as an unknown device, shows a warning in Device Manager, or is unavailable to your mobile connection software.

Key Features

• Provides driver support for the 3G PC UI interface, allowing compatible connection or management software to access the device.
• Enables Windows to identify the interface as a COM port. Although this device is labeled COM17, Windows may assign a different port number after installation.
• Supports use on Windows 10, 8.1, 7, Vista, and XP when you select a package matching your system version and architecture.
• Helps address recognition problems caused by missing or incorrectly installed drivers. This interface driver alone does not guarantee mobile internet access; other device components and connection settings may be required.

How to Install TCT Mobile Connect – 3G PC UI Interface (COM17) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, review the device’s hardware IDs to help verify that the driver package matches your hardware.
2. Choose a compatible package. For your TCT Mobile Connect – 3G PC UI Interface (COM17) driver download for Windows, select the latest version explicitly supporting your device and operating system. If offered as a free download, still check its source and compatibility.
3. Extract and install. Unzip the package if necessary, then run its installer. Follow any instructions about when to connect or disconnect the USB device.
4. Use Device Manager if needed. If no installer is included, right-click the affected interface, choose the option to update its driver, and browse to the extracted driver folder. Menu wording varies by Windows version.
5. Verify recognition. Restart if prompted, reconnect the device, and check that the interface appears without a warning icon. Configure compatible software to use the COM port Windows actually assigned.

Keep the driver updated when a compatible release addresses a problem you are experiencing. For Windows 10/11 systems, check support carefully: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed. Avoid forcing an unsupported update, and retain a working driver package in case you need to roll back.
