How do I activate my Ubigi services with my Windows 10 or Windows 11 device equipped with a Ubigi physical SIM card?
First, make sure that the SIM card is well inserted in the SIM card slot of your device (please refer to the instruction manual of your device).
Then, the only thing you have to do is to connect your device to the Ubigi network and create your personal account. To do that, please follow the instructions here.
Voilà ! You can now enjoy your Ubigi services.
Note: in case there is no SIM card inserted in your device, first make sure it is compatible with Ubigi service: Which Windows 10 or Windows 11 devices are compatible with Ubigi services? If it is compatible and you never had a SIM card or you lost it, please contact device manufacturer directly to request a new one.

Great choice of eSim
My eSim started working immediately when I turned my phone on in Japan. There were only very few occasions when it didn't have cover. Mostly in remote hilly regions. I travelled in Honshu, Hokkaido and Shikoku.
It was invaluable for negotiating public transport in Tokyo and Kyoto.

In October 2026
In October 2026, we took a week-long road trip to see the fall colors, flying into Memanbetsu Airport and driving west from the Shiretoko Peninsula. We even took a short boat cruise along the coast. I was surprised that we had Wi-Fi almost everywhere! I’m so glad I chose Ubigi.

Used Ubigi eSIM for a recent trip to Japan
Used Ubigi eSIM for a recent trip to Japan. So easy to download in advance then activate on arrival in Japan. Received discount code so applied that when setting up another eSIM on my husbands’s phone - great value. Can also add extra data if needed at any stage. Great price, great service, would highly recommend.

After a few clicks works beautifully in Japan
Thee are several manipulations to do before use - once that’s figured out, it’s very easy to switch between local wifi and Ubigi. Highly recommend.
