  1. Rated 5 out of 5


    I’m so pleased to have stumbled upon this product before my trip to Japan.

    I would have been lost without it (for real!) and I would recommend to any traveller to Japan.

    The only downside is you don’t get a physical phone number and can only use your phone for the internet but as I was only away for the week it wasn’t too much of a problem…

    Thank you Simcard Geek!

    Habe die Karte für unseren 14 tägigen Japan-Trip bestellt.
    Das Preis-Leistungsverhältnis war wirklich hervorragend! Wir haben als Familie einen WIFI-Router mit Akku eingesetzt. Es verbindet mit dem OCN-Netzwerk und wir hatten fast überall 4G! Insgesamt wurden über 25GB an Daten verbraucht. Wir werden diesen Service bei unserem nächsten Japan – Besuch benutzen.
    Wirklich empfehlenswert! Kostenloser Versand und TOP-Leistung
