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.

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.

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.

Connected immediately + throughout Connected immediately. Great connection throughout the trip - my family members had issues with g.maps (they were using a physics sim) but I never did. Cheers ubigi!

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
