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.

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.

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.
