I experienced no issues with using Ubigi eSIM. Connected when I arrived in Japan and never experienced a delay or any issues. I'm a second time user and wouldn't hesitate to use Ubigi again if the need arises.

Good...but..
Easy to set up, use and renew or top up. Coverage was sometimes patchy but that could be due to the local telecommunications companies.
The unlimited plans for data are still capped and then you still get data at reduced speeds. I took off another star because of this, when in this day and age, unlimited data should be as described.

First time to use Ubigi eSIM
This was my first time to buy and use Ubigi eSIM for my stay in Japan. It’s been so convenient and I feel safe since I don’t have to worry about the availability of WiFi. I can use it wherever I am even in a rural area of Japan. I can use it in trains, buses etc. I’m 65+ and didn’t have much knowledge about SIM card, but with instructions I was able to set up eSIM before I left for Japan. After I arrived in Japan I just turned on Ubigi eSIM. That was it!!

Great service and esim!
Esim worked perfectly the entire trip and was exactly what we needed. Good value for the price! Would definitely use again if I get to travel back to Japan again!

The connection was not immediate
The connection was not immediate. My friend with another brand was able to connect first at the airport. Mine maybe another 10-15min later after I tried to configure the access point name (trying to troubleshoot by googling). In the end Im also not sure if that helped. But once it is connected, everything went well, no hiccup, no complaint.

eSIM easy and effective
The eSIM was easy to buy and install. Clear instructions on their website.
Most importantly, the data plan worked well while I was visiting Spain. I had signal everywhere I went in Madrid and Barcelona.
