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.

Buggy and no support help I topped up my plan and my eSIM broke. Removed it and restarted my phone but it wouldn’t let me reinstall for some reason (kept getting errors) so I tried to reach out for support only to find your websites certificate expired which meant I couldn’t access it at all in Safari. Gave up and just did a charge back with my credit company and enabled AT&Ts international plan… Edit: Absolutely LOVE the canned response from their support team. I have screenshots of the error I received trying to re-add the eSIM (followed their instructions exactly) and the error about their certificate expiration, so yea… absolutely garbage response from their team, their product is just whack.

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

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.

Decent Very convenient and easy to set up. However, the used data does not seem very accurate as I barely used any data but it still decreased with 4 GB (out of 10 GB). The app also keeps logging me out when I want to check how much I have left. Next time I would consider using another provider which has unlimited data
