Great service
Great service. Be careful about apps though, especially ones that run in background, and news apps, with videos, they hog a lot of the allotted capacity.

I used it in Rome and Naples. It worked in the city very well but out of cities not so well.

Will always recommend
This is my second eSIM purchase with Ubigi and I was more than satisfied! We traveled in 3 countries in Asia ( Japan, HK and Bali) and had more than enough data for the 3 weeks of our trip :) I didn't have any issues with the internet and the signal was always good. Definitely recommend!

While in Japan
While in Japan, this eSim worked great. I prepped before my flight over, and once I was on the plane, I went ahead and activated it. So easy! When I arrived, my connection and signal were strong!
I used Google Maps and Translate quite often for a 2 week trip. With that said, I actually topped up after one week. I was able to do so easily.
I will say this is pretty straightforward. For folks that do not understand their personal phone plans and how data / Wifi work, I would call your provider to verify.
I actually turned off my T-Mobile Sim while using Ubigi just to avoid calls and accidentally answering them (international charges). I only turned on my T-Mobile sim temporarily for any MFA via text (like for online banking). Any calls while being in Japan were done on Ubigi data or WiFi via WhatsApp.
Highly recommend for use in Japan!
