It was a little complicated but the service and support team were great It was a little complicated getting the service set up for our phones. We weren't aware that we had to pay off our phone first before being able to utalize this service. Also, it was confusing linking up the eSim to our phones. However, nonetheless after getting it all set up, it worked amazing. The support team was very helpful in refunds and setting everything up.

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.

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.

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.

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
