See what makes us the best Japan eSIM
Worked a treat!!
I picked up a JJesim on my recent visit to Japan.
I ordered it the night before boarding my flight and it couldn't have been easier to set up. I was up and running before I even got off the plane at Haneda. I didn't have any issues during my visit but it's fair to say I didn't really venture far from the beaten path.— Adam We
The Best eSIM for Japan—Plus Incredible Support!
The Journey Across Japan eSIM is perfect for my travels—it simply works! But what impressed me even more was their customer service.
— Nathan Zee
Perfect
Just sent 3 weeks in Japan, Tokyo, Osaka, Kobe, middle of Disney, didn't matter, I maintained fast and consistent internet. Very impressed!
— Tom Barker
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.
Worked effortlessly
I’ve just got back from a 3 week trip and had no issues at all using the jjesim. It was easy to install and just worked!
