    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!
