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.

Necessity of switching off primary SIM
First, I cannot connect internet. I can connect internet after when I switch off primary SIM. It is more comfortable if there is instruction about necessity of switching off.

We chose Ubigi because we read that it had great connectivity in more rural areas of Japan and it didn't fail us. It was easy to upload and use and had no issues at all. I would highly recommend them for anyone wanting a reliable E-sim.

Would’ve liked more plan options
Would’ve liked more plan options. Such as 7,11,15 day options because I needed 8 days of unlimited data but had to pay for 15.
Had trouble making phone calls with the data plan.
