Used UPeSIM in Japan

Got the 6GB 12day eSIM for Japan while the installation was pretty straight forward on my iPhone 13, I had issues with connectivity. I had full LTE bars no matter where I went but the internet was always dog slow. Despite having full bars in the middle of Tokyo my pings were 150ms with 7mb/s up and 3mb/s down. I ended up doing an investigation and found that all of the data was bring routed back to Hong Kong based on the IP addresses I kept resolving to. Later found out that you're basically roaming on China Mobile's network and my theory is that they're routing your connection back to their network in HK since everytime I looked up my IP, that's where it resolved to.

For those who are looking for fast speeds or don't want a Chinese network reading all of your data look elsewhere. If you're okay with 3G speeds then this is a cheap answer.

Used UPeSIM in Japan

I was unable to activate it at all due to an unfriendly email. The QR code I received by email is unreadable and broken, and no refund will be given. I think only people who can contact them in English and fight could get a refund. Their reply is also slow.
If you don't have time, you should just go for other sims with good reviews in the first place! :-) don't waste your money.
I will write another review if they will take appropriate action on this review.

Used UPeSIM in Japan

The company is based in France and payment is in Euros, but for some reason the information on the QR code sent to me is recognized as a Chinese telecommunications company.
The SIM APP field on my iPhone also shows china unicom HK. I was scared, but I had no choice but to activate it because I had already bought it and my GB with my usual carrier in Japan was about to end.
The Japanese carrier is Softbank, but I couldn't connect to the internet, so I set it to 3G and it worked. It's not fast, but it's fine for normal web browsing.
I just hope they don't steal my personal information or send me strange bills.
