Bad Internet Reception The experience was very bad and disappointed, especially when you're in the train station. Can't get Internet when you need to travel from one place to another place, even in your own hotel room also couldn't get connected. Very angry and won't use the service again.

Perfect! I could get just the right amount of data for my trip. Setup and purchase was incredibly easy! I will definitely use Ubigi again. Coverage was great, even in rural areas of Japan.

Clear instructions on how to setup… Clear instructions on how to setup correctly the parts that can not be automated by the app. The service itself does exactly as expected, for reasonable prices.

Great reception everywhere we went. UI needs improvement. Worked well and had reception throughout it everywhere in Japan that we visited. Reception persisted and we had coverage in stations and on trains and in theme parks where the signal could otherwise be disrupted. The only reason why I would dock a star is the lack of ability (or obvious ability) for me to check the remaining data on the app, and the lack of clear instructions around installing and using. Pro tip: don’t buy on a computer or browser. Instead, download the app and use the app to purchase the eSIM. The instructions should be outlined on the website and the website should link to the App Store.

Very satisfied I was very happy with the purchase of my eSim. The installation went smoothly and the internet worked all the time, so no complaints! One thing was that my siblings both got the same eSim, but they went through it much faster for some reason.
