    I thought it looked a bit dodgy but when for it and it works absolutely beautifully! The only thing is there isn’t a platform to see how much data you have used, but you can use your phone’s data usage reading for an idea. Lots of super fast data across Japan. Highly recommended!

  2. AR

    Amazing value! I’d used Airalo for international data SIMs in the past, but this looked too good of a deal to pass up. Backed by Mobal, a huge name in Japanese SIMs, I trusted my experience would be smooth, and it absolutely was! Fast, reliable all around Japan, from large cities to rural prefectures. Was often a lifesaver when my companion’s expensive T-Mobile data wasn’t working, and I could hotspot them. Excellent step-by-step guide for editing APN settings included, which made getting connected a breeze. Can’t wait to visit Japan again, and will happily use Sim Card Geek when I do!

    Wasn’t sure about the website at first, but took a chance based on positive reviews around the internet. I’m glad I did. The value of the 50GB cards is unparalleled, and the setup was easy too. I used it in a lot of rural areas like around the edges of national parks and it worked great.

    Amazing deal. Just got back from at 14 day trip to Japan, visited multiple regions, absolutely no connection issues and fast speeds. Highly recommended. Will use this again the next time I return to Japan.

    I can fully recommend this sim, it provided good value and connectivity everywhere for our 12-day trip in Japan. Used in Pixel 7, an Android phone. As others have pointed out there was a lack of recommendations or reviews for this, and I too was a bit sceptical. But having used it without issues, I would recommend it to anyone. I used it personally and tethered to other members of the family during the trip without any issues and found good value in usage compared to other providers. After you receive the activation link, during the process of activation, a secure code is generated. A crucial part of the set-up is this code, and take care you don’t lose access to the page before you activate your sim. Either copy the code securely or take a screenshot of the QR code. Esim can be installed only on one phone and can’t be transferred.

    Just came back from a 16 days trip. Bought the eSIM two days before leaving and Installed it a day before. Activated upon arrival and turned off my main eSIM. Installation was straight forward for iOS. Worked perfectly everywhere from Tokyo to Hiroshima, including on trains and in Hakone. Hotspot worked also great. Overall, great value and as far as I can tell, the best price for trips of this length. Side note, a friend installed his on a Samsung phone and it was more difficult to activate, because of a couple more steps – just make sure to read the instructions, they are accurate and complete.
