Customer feedback

  • the internet connection
    stable

    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.

    50s/Male

  • 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.

    20s/female

  • Even if multiple units are connected
    Fine

    ​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.

    40s/Male

  • remote work too
    without hindrance

    I have no problem with online meetings and watching videos. I am satisfied because I can use it cheaper than other companies' lines.
