4G eSIM for Japan
- For traditional mobile phone usage, it is necessary to replace the physical SIM card, while the eSIM card is directly integrated into the smartphone/ tablet/ smart hardware device, and does not need to be installed separately. This not only allows mobile phones and other devices to achieve better sealing, but also reduces the thickness of devices, and more importantly, allows users to better switch between multiple operators, while saving the trouble of changing cards.
- Before you activate the eSIM, please check if your mobile device is compatible with eSIM by the following method. 1) Type: *#06# in "call"2) If you see the "EID" in your Device Info, then your phone is eligible for eSIM.

Reviews
doesn’t work. still awaiting details and refund from klook. Very disappointed with the way this has been taken care of
Because I bought 3 of them and they didn’t work, I immediately bought another one and it still didn’t work. What’s going on?
This eSIM was very convenient to use on my Japan trip. I would have rated 5 if not for issues with mobile data not working even after enabling data roaming and all of the other basic steps. I had to connect to a WiFi, search google and set up custom APN on my S23+. Being a tech savvy user, it was still painful for me.
the sim was not working so i requested for a refund. might be due to a connection-compatibility issue with our local network provider
unable to use at first but works after contacting the customer service
E-sim didn't work. I had to buy another one from different provider only to end up with 2 not working e-sims. Had to chat with the CS team 3 times, and they all closed my ticket without solving the issue. The worst experience.
pretty good and stable connection. does the job. works fine in Osaka
Super easy to install, fast and stable internet everywhere. Worked very well with a Google Pixel 8 and could give hotspot to my kids as well
The second time I repurchased it, the experience was completely different. I went to Japan in April this year and bought a network card here. Everything went smoothly. I decided to use the same company this time when I came to Japan. Before boarding the plane, I wanted to activate the eSIM first, but the result showed that it could not be used. I contacted customer service, who helped me check and said that I exceeded the 30-day period, but I only placed the order on 9/12, and it did not exceed 30 days no matter how I calculated it! Later, the customer service only gave me the contact information of the merchant and asked me to contact the merchant myself. I wonder if I can help with other compensation methods or refunds, thank you.
Except for a few places (department store basements) where the signal is weak, there are no problems and it works normally.
