Second time using Ubigi in Japan - both times no issues at all. Fast connection. Highly recommend!

Great service, but referral policy needs improvement
Overall, I have been very satisfied with Ubigi’s pricing, network quality and reliability.
However, I find the referral program disappointing. Because my very first purchase years ago was made through the website, my existing account is permanently excluded from the program, even though I now purchase plans through the app.
I find it unfortunate that the original purchase channel matters more than customer loyalty. This was also not clear to me when I made my first purchase.
I hope Ubigi will reconsider this policy in the future.

Ubigi esim helped my trip a lot
It helped me during my trip so wonderfully. It took me a long time to read and chose the right kind , and understand the instructions before going on the trip. However it was easy to start using after I arrived Shanghai, then EU countries. I bought China for transit time and unlimited Europe for 15 days for visiting France, Spain, and Germany. I spent my travel time with a very comfortable wi-fi condition.

Reliable & activation only when you join your destination
I used Ubigi for the first time this year in Japan, I faced no issue and that worked properly from my airport arrival to my departure. Network coverage was ok. For a normal usage I recommand 1 Go by day for navigation, translation and restaurant searches. More if you used massively social network.

The app is easy to use and the connection is good. The subscription price is reasonable, but I find the extra data a bit pricey.

Great impression
It was an excellent experience for my first use. I simply had some bad Network sometimes but overall it was fine. I will definetely recommend it to my colleagues.
