I used the Ubigi esim in my recent 31 day visit to Japan and found it provide excellent data connectivity anywhere that I went. That included long hiking periods in the Japanese Alps and various countryside trips around Tokyo; Matsumoto, Takayama; Kanazawa and Osaka. And it was so easy to top up on my last day. Very happy with Ubigi.

Get the unlimited plan! Worth it.
I loved it but I ran out of 5GB on the first two days and Im not sure how. Definitely wasn’t using that much. But once I switched to the unlimited plan, I had zero problems. Honestly, the best app of the trip.

Small issue at the beginning
Small issue at the beginning since the app told me "it's OK your iPhone 17 can have eSIM", and when I crossed the border, the app went "Your phone cannot install eSIM".
Customer service were not helpful.
After 10 minutes, the app changed and I could install the eSIM. After that, no issue at all, everything went perfectly well using data in Switzerland.
