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.

Great coverage in major Japanese cities!
I had really solid 5G coverage in Tokyo, Kyoto, and Osaka. Worked well in those deep train stations when you really needed it to find your way on Google maps. Some minor drops in some more rural areas and in far off mountain hikes to temples. But I assume everyone was in the same boat. I would highly recommend this e-sim and definitely use it again for my Samsung 23 phone.

Travel eSIM
Easy to buy and install an eSIM whilst on holiday, good range of products. The dashboard on the App worked well and just a few clicks to buy a new plan when first one expired
