Overall I’ve been really happy with this SIM which was easy to set up and works well. Only thing I’ve marked it down on is there is a fair usage limit of 30gb so just need to be aware of this if using for streaming/tethering etc. To be fair though you don’t get cut off - it just limits speed to 2mb

Reliable and Easy eSIM for Travel
I only heard about Ubigi less than a day before my flight to Japan! A friend highly recommended it, so I decided to switch from the eSIM brand I was originally planning to use and I’m really glad I did.
The setup and navigation were super easy and the signal was really reliable throughout my trip. The only time I had a little trouble with the connection was at DisneySea, which was completely understandable considering there were thousands of people in the park at the same time. Even then, it still worked pretty well.
Overall, I had a great experience with Ubigi and would definitely use it again. Highly recommend it if you’re traveling to Japan!
