We used the Ubigi eSIM during our trip to Tokyo
We used the Ubigi eSIM during our 10-day trip to Tokyo, and the experience was excellent from start to finish. The installation process was quick and straightforward, and we were connected within minutes of arrival.
Throughout our stay, the coverage was outstanding — we had a stable and fast connection everywhere we went, including busy areas, public transport, and even more remote spots around the city. We never experienced any interruptions, slow speeds, or connectivity issues.
Having reliable internet made navigating Tokyo, using maps, and staying connected incredibly easy and stress-free. Overall, Ubigi exceeded our expectations, and we would definitely use it again for future travels. Highly recommended!

Works well in Mexico
Works well in Mexico.
Only difficulty was getting started for the first time with an eSIM.
I suggest you have a page for first time users, saying things like whether you do or don’t activate airplane mode and other
