Ubigi Works well in Japan. Ubigi Works well in Japan. Some strange apple reporting on data usage worried me a bit, but apparently it was just Apple over reporting usage. Maybe a FAQ about this would be good.

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.

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.

First time e-sim user As a first time e-sim user, Ubigi provided a simple, easy to use and efficient option. Would recommend and will certainly use for future travel.

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.
