The Ubigi antenna pictogram is not displayed in Japan, why?

In Japan, Ubigi works with two telecom partners: NTT Docomo and KDDI.

NTT Docomo – When connected to the NTT Docomo network (sometimes also displayed as Ubigi), the antenna pictogram will appear normally on your device.

KDDI – When connected to the KDDI network (which may also display as Ubigi), the antenna pictogram might not appear at the top of your screen. This is due to differences in network protocols between Ubigi and KDDI.

⚠️ Important: Even if the antenna pictogram is not displayed, your internet connection will still work. You can browse, stream, and use online apps as usual.

This ensures you can enjoy seamless connectivity in Japan, regardless of which partner network your device connects to.ed, your connection will work, so please try your connection and you will have access to the Internet.

It worked fine
It worked fine, except on my last day in Greece. I had used 3.x gb of 10gb and it didn't work for several hours. It was annoying. When I got home and saw an email to review, I was going to give less stars, but then saw that they offered a one-time 50% off of any plan for a year for the inconvenience, so good customer service.

4 weeks in Japan 10G
Used a Ubigi data only eSim traveling around Japan for a month. No issues worked everywhere, cities and Rural. 10G was plenty for Google maps and normal internet searches. I did switch phone to Flight mode each night. Will use service again when return to Japan.
