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.

I used Ubigi in my trip to Japan…
I used Ubigi in my trip to Japan (Tokyo+Kyoto). At first internet worked really well but at the end of the trip it started to get slow and for a short period of time it didn’t work at all. There was a taifun in Japan at the time we visited and although it didn’t effect us directly otherwise it may have had an effect on internet connection.

The ease of installing
The ease of installing would be the reason why I would use again. My reasoning for 4 stars (and not 5 ) was due to the fact that my dashboard claimed I had over 0.5g left, but I was not able to use anymore data.

Budapest and Ubigi
I have just come back from a trip to Budapest and wanted an E Sim for data instead of relying on Wifi. I decided Ubigi would be a good choice, and it was. I had a whole week's data for 9 euros. It was so good to be able to use it for Google Maps, and navigating the public transport system. I was impressed.
