^*it will appear as “secondary” or under the name you renamed it.

NB: The Data roaming option is now activated only for your Ubigi eSIM profile. This means that you won’t have extra roaming costs as only Ubigi rates will be applied while using the Ubigi cellular connectivity.

In the same screen, select Mobile data network in order to configure the APN (Access Point Name). In the APN field, make sure that mbb is specified. If not, type it in the field.

Great for busy Tokyo streets and Mt Fuji hills

Sim worked great around the busy Tokyo streets, the underground trains and metros and in the hills of Mt Fuji. Didnt notice any drop in speeds at any point during 7 days usage even when watching YouTube videos.

Just works without issues

It worked

It worked. I liked that I could check before I left that it was installed correctly and just turn on roaming when I got to my foreign destination. Videos were also helpful. Will recommend to others. Wish had more options for unlimited data plan like for 5 days or 10 days. 15 was a little too long. I won't be using for remainder of 5 days. But still reasonbable.

I needed mobile Data for Japan

I needed mobile Data for Japan. I took the 30 days with 10 GB for 17 €. It was working good also outside the big cities. After 10 days I have left 8 GB, but I just use I it for Navigating, tranlations and Internet
