So simple to install and set up. The coverage in Japan was perfect. I selected 5 GB for 2 weeks and actually only used just under 3.5 GB.

This saved my life and wallet
This saved my life. Never disconnected, and I only got to use 6gb out of the 25gb. I was always connected to Google Maps and was talking to people on WhatsApp, Viber and Messenger. Was even able to do Video Calls a lot. I would definitely buy it again when I visit Europe again (I am from Asia). Hassle free.

I would rate the cellular data service 3 stars, but thanks to customer service 4 stars!
I would rate the cellular data service 3 out of 5 stars overall. However, the prompt and outstanding response from customer service was remarkable, which is why I’m giving it 4 stars overall.
The service in Spain was noticeably better than in Italy. Overall, though, the connection was often laggy and not as fast as I had expected. Hopefully, this will improve as Ubigi expands their partnerships with more reliable mobile networks.

I used Ubigi eSim in Japan and it worked perfectly. It was pretty easy to use especially since it was my first time. Will definitely keep using it and would recommend it.

Everything was smooth
Everything was smooth. From the setup to the end of my trip. The instructions given on how to make sure my phone was active when I arrived in Japan was just right. We had no issues getting connected the minute we landed. The service was great all throughout the trip. Mostly 5G some LTE here and there but for the most part fast speeds throughout. I’d recommend Ubigi to anyone traveling to Japan as it’s was very cost effective the we were connected the entire time.
