Trip to Japan - April 2024 I was thoroughly impressed with the delivery of the service (in app) and the reliability - I have already recommended your services to other people before they go to Japan. This was much better than using a pocket wifi. The only glitch was when I couldn't check the "balance" of my usage as often it would say ERROR - but it seemed to update in real time and I didn't go over my 10 GB purchase. Thank you very much again :) Happy Customer X

Very satisfied I was very happy with the purchase of my eSim. The installation went smoothly and the internet worked all the time, so no complaints! One thing was that my siblings both got the same eSim, but they went through it much faster for some reason.

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.

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

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.
