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.

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.

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.

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

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.
