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.

This just made my trip to japan… This just made my trip to japan possible We had a great experience with Ubigi, it has awesome network and coverage in Tokyo, Kyoto, and surrounding The speed and ease of adding extra credit made everything much more enjoyable

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.

Poor customer support Ordered 2 esims for Japan data. Was able to install on one device, but not on the 2nd. Even after installation, device 1 did not have data (activation missing perhaps). Raised complaints on ubigi support for both orders - no response. No option to email or call customer service. Terrible experience overall. Edit-26.04.2024: No response from the support team, even 3 days later. Note: To continue with our vacation, we ordered esims from Airalo and Nomad, and both devices were working fine.

Very reliable Worked from the moment I stepped outside the plane until I left. Speed was okay. A little expensive compared to local options but I'd gladly pay the premium for the ease of use and convenience. Coverage was good for the most part except for one or two times when 5G wasn't available and it had to fall back to an LTE connection - but that was not their fault as those are mostly remote locations or very underground. Will use again next time I go on a trip outside the country.
