As soon as landing at Narita airport on May 27, 2026 my cellular 5 bars are strongly risen up.
So far working well around Tokyo. A brief disconnection was experienced on the way back from mt. Fuji but ubigi was aware and apologized for disruption.

Very good option for Kumano Kodo
Even though there were a few bad reviews on this esim I found it super reliable for Japan's countryside. I did the whole Kumano Kodo in Wakayama using this esim and even in areas with poor reception it proved to be very useful and contstant!

Very easy to use and worked perfectly
I’m really happy with my experience! The eSIM worked very well and was easy to set up. The instructions were clear and simple, and everything worked from the first moment. I really appreciated being able to track my data usage in the app and see how much data I had left. It was also very easy to top up when needed. I would definitely use this service again!

Overall good but there was a 10-14 hour period where the service was down. Thankfully I could find wifi to supplement, but it would have been bad if I wasn’t able to.

A good ESIM
I had to change eSim providers whilst in Japan as the one I was using was very troublesome. Many Ubigi reviews were positive, so I downloaded it. Found it easy to set up and it worked very well. There was one small outage, but Ubigi have corrected it and offered compensation, great integrity.

Perfect Experience
I used an Ubigi eSim for my two weeks in Japan. It was my first time using an eSim and the process was very simple. The app explained it well and I had no issue with activation.
I purchased an eSim with unlimited data for peace of mind. I used it frequently and daily, mainly for social media, communicating with family and navigating Japan. I had no issues with connectivity in Tokyo and Osaka. I would absolutely recommend Ubigi and will definitely use it again later this year for my next travels!

It’s a must-have when travelling abroad. The eSIM was easy to install and came with clear instructions on how to change the mobile settings upon arrival.
I experienced some downtime for a few hours, but the follow-up service was excellent.
I would recommend Ubigi to all travellers!

The eSIM was great
The eSIM was great. Worked As soon as I landed. It did take a bit of time following instructions to load the eSIM as QR code did not automatically work from email.
Would definitely use again,
