Clear instructions on how to setup… Clear instructions on how to setup correctly the parts that can not be automated by the app. The service itself does exactly as expected, for reasonable prices.

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!

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.

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
