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.

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.

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.

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.
