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.

“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.”

“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.”

UPeSIM for Japan FAQ

Does UPeSIM offer unlimited data eSIM for Japan?

UpeSIM does not provide an unlimited data eSIM plan for Japan. The available Japan‑specific plans are fixed‑data offerings, such as the Japan eSIM 10GB 30 Days and the Japan eSIM 5GB 10 Days. For travelers who need more data than these plans allow, selecting a fixed data plan can often be more cost‑effective than seeking an unlimited option, unless they are very heavy data users.

Does UPeSIM offer Japan eSIM with phone number and SMS?

UPeSIM does not provide any Japan eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only plans for the country. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that those services are accessible in Japan before purchasing a plan.

How many data plans does UPeSIM offer for Japan?

UPeSIM provides a total of nine data plans for Japan: three single-country plans and six multi‑country plans. The single‑country bundles give a fixed amount of data ranging from 1 GB to 10 GB, while the multi‑country plans can combine Japan with other destinations and also offer data limits in that same range. Prices across all plans fall somewhere between roughly $3.42 and $114.39, giving travelers a broad spectrum of options that balances cost, validity and data volume.
