  • It just works!

    Everything just worked? Mom and I traveled to Japan and I decided we'd try two different eSims and my phone had the JJ eSim and it just... worked. We had to jump through hoops and the other sim didn't get fully setup for a couple of days. I did have consistent 4g in both Tokyo, Osaka and Kawaguchiko. I had never dealt with eSims prior to this and enjoyed this experience greatly.

  • I will just be buying JJESIM every time I go to Japan

    Great eSIM. I used to buy the portable wifi at the airport and have to go through the hassle of getting it at the airport and returning it. Now I will just be buying JJESIM every time I go to Japan. Can't recommend it enough.

    — Gordon W.

  • Highly Recommended

    We had a full 3 week trip in mostly rural areas of Kyushu and the beaches of Okinawa. this worked very well for our whole trip! I would wholeheartedly recommend this sim to anyone interested in travelling to Japan.

    — Scott M.

  • Cheaper than roaming plans

    It was so easy to setup. Once setup it just worked so I didn't have to worry about not having access to data. It was cheaper than using roaming and definitely more reliable. I was using it on forest walks in Furano to streets of Kamakura. I will definitely use again on our next trip to Japan. I used it for 18 days and didn't use up the 20GB. Thanks for creating Chris and team.

    — Jellete E.

  • Transparent Pricing

    I like how transparent the website about what to expect. Very prescriptive on the plan descriptions. More power to JJ eSim team!
