Thanks to the new SmartStart feature, your data plan activates automatically upon arrival in a covered area, starting its validity period. This ensures you can fully use it without losing any days before your travel.
Once purchased, your data plan appears in the “My Account” tab on your Ubigi account, where you can track data plan usage and renewal details.
Getting started with SmartStart is easy! 🚀 Upon arrival, simply switch on your Ubigi line in your mobile settings—your data plan will activate automatically, and its validity will begin.
Note: If you are already in a covered area when you purchase the data plan, activation starts immediately.
What happens if I don’t activate my data plan right away?
If your data plan is not activated within six months of purchase, it will automatically expire and cannot be used. To avoid losing your plan, make sure to connect to activate your Ubigi eSIM within this period to activate and begin using your data plan.

Ubigi offers a range of packages easy to understand not overwhelming. Competitive prices. Step by step download, set up and simply connected on arrival. Coverage in Japan in the countryside where I am in Nagano is good. Many reviews say when things go wrong not so good but as it hasn’t so far happy except that slight angst of if I have a problem…… that’s why it’s a 4

The user experience is great
The user experience is great: buy your plan a few days before leaving for your journey, and the eSIM activates as soon as you arrived to your destination. Also, you can choose the country of your IP: very convenient not to be blacklist by your bank website because you're in a foreign country.

Everything was great
Everything was great, except for error codes. When no internet error, the app said "incorrect code". Would better understand "no internet error" so no password reset

Great for accessing data in Japan
Was great at giving me access to data while in Japan. Good value for money and relatively easy to set up (Im 61 and not particularly tech savvy)
