Customer feedback

  • Satisfied with comfortable internet environment

    I changed my internet speed to 1G course last year. The line is fast and stable, and I am very satisfied. I'm glad I made the change.

  • Stable internet connection

    After switching to J:COM, my internet connection became more stable. Wi-Fi is also comfortable and uninterrupted, probably because it automatically connects to an easy-to-connect Wi-Fi.

  • Multiple units can be connected

    I have connected multiple Wi-Fi devices such as PCs and game consoles, but I can use it without any problems. Enjoy online videos without stress.

  • even in the bathroom
    comfortable internet connection

    I am using additional pods. Wi-Fi is now connected even in the bath where Wi-Fi was difficult to enter, and the enjoyment of bath time has increased.

  • Security software
    I'm glad it's free to use

    We recommend that the McAfee usage fee is included in the internet service. It cannot be replaced by any other provider.

  • Remote support even when you are in trouble
