Easy to connect. Worked well
I travelled around Honshu from Tokyo, to Echigo Yuzawa, Karuizawa, and Kusatsu, and I had no issues at all! Able to make video calls home, upload photos, and navigate around Japan without any problem. Will use next time I’m in Japan for sure.
Great connection and easy to setup. Even worked smoothly at Expo 2025, where there were more than 150,000 people inside. The only time I don't have signal is on top of Mt. Hangetsu deck but hey it's expected.
I had issues with activation but it was resolved immediately after contacting support. Ive had this issue with another company before and it would not work. This one ended up activating right after troubleshooting. Not to mention this was the lowest price I found out of all esims (Sally and other popular ones). Happy with my purchase
