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.

easy to install, cheap and easy use. just if can provide report of daily use would be great ( as I only purchase 500mb daily) otherwise I have block all unnecessary apps to ensure use for navigation and communication purpose only
super convenient to use! activated it 24 hrs before flying to japan. internet is reliable even if I’m in Fukuoka. I used it really well. More convenient than other connection options. highly recommended
Used this in Tokyo & Nagasaki and speed is fairly fast. I use an openline Samsung Galaxy S23 ultra bought from the Philippines and have no problem registering the Esim or connecting to the data. Will book again! ❤️❤️❤️❤️❤️
Bought 2 lines of the 10gb package. Pretty easy to activate esim. You can activate first and it will connect when you reach Japan. If not you will need a stable internet connection when you reach Japan. Speed is good and quite stable throughout our trip in Tokyo
Hassle free connection with e sim. No need to pick up and drop off pocket wifi to and from the airport. A must when traveling, was able to capture Japan and share it in social media because of the fast connection also booking made it is easier because it is available at klook always. Thank you klook!!
No problem in connecting to the network. I think this is the cheapest option & I’m glad in using it. I tried to connect it in SG airport first then when I landed in Japan (Tokyo), it was alright. Need to know that cannot “share hotspot” with friends. Used the esim for Tokyo area (e.g. Disneyland, Fuji Q Highland, Daiba, Kawagoe & Shibamata) & no issue with network.
At first, I was worried that it wouldn't work but I'm glad it did. It's just sad because the price was supposed to be for 30days when I first checked it but they reduced it to 25days with the same price. I am staying on a more province side of Japan and the signal still works perfectly fine. 😊 It's very helpful for your google maps needs when you're lost in the metro.
Initially have some issues due to the date or purchase after chat with customer service and manage to solve the problem. The speed is good never face any data reduce speed…
tookma chance, almost regretted it. but customer service was prompt and accurate and very helpful. we just needed to change apn settings and we were good to go. purchasing this again!
worth it for my 25 days stay. no hassle, voucher sent on the email and east to activate. internet speed is nice too. will book this again for sure.
