Mostly great experience overall
Used Ubigi multiple times now across multiple trips in Japan. It's super easy to use and has good connection for the most part. I had no troubles adding the e-sim and activating it on my phone. It's my go-to service for now.
I docked 1 star because when I used it in August during a fireworks show, neither my wife nor I could get signal. This made it really difficult to regroup with our friends on site. Our Japanese friends were online just fine, so maybe Ubigi clients got de-prioritized by their carrier partner in Japan.

Highly recommend the fixed-data plan for Japan
I bought the fixed-data plan for Japan and it worked smoothly from activation to daily use. Apart from one or two brief moments where the connection dropped, everything was reliable. Having 5G available on top of an already competitive price was great value. The app made it easy to manage the plan as well. I’d definitely use Ubigi again on my next trip.
