Why choose Ubigi?

In our Ubigi review, we praise the company for having affordable and flexible data plans. When users are choosing an eSIM for international travel, they are looking for an eSIM that is reliable, affordable and provides excellent coverage in the choice of their destination.

Ubigi is a full-fledged MVNO, meaning they can directly optimize local telco partnerships to make sure you always stay connected to the fastest available network wherever you travel. With flexible data plans, users can choose from 1-day, unlimited, global, or regional options. For example, if you're traveling to Japan and other Asian countries, the Asia eSIM plan will cover your entire trip. Annual plans are also available if you travel a lot, offering long-term convenience.

And if you are running out of data, there are several top-up plans available easily through the Ubigi app. The app itself is designed to simplify travel, not complicate it. We've found the app to be user-friendly during our testing.

If you run into any issues either setting up your eSIM on your phone or with your Ubigi account, there is a detailed FAQ page with tutorials and blogs. While direct customer support isn’t available, you can reach the team via a support form though response times may vary.
