The mobile data is very slow in Niseko. Doesn’t load most things. Not worth it.
Hello,
I am writing to report a serious issue with the Japan eSIM I purchased from your website.
I am physically in Japan and using an iPhone 14 Pro, which fully supports eSIM.
The eSIM was installed successfully via QR code and initially showed a brief 4G connection for a short moment. However, shortly after, the connection dropped completely and has not worked since.
Current behavior:
– The eSIM can see Japanese networks (NTT Docomo, SoftBank, KDDI, Rakuten) during manual network search.
– Selecting any of these networks results in no registration.
– The phone only shows SOS / satellite mode.
– No LTE/4G/5G signal appears.
– Data roaming is enabled and the eSIM is set as the primary data line.
– Other eSIMs have been disabled to avoid conflicts.
This indicates that the eSIM profile is not properly provisioned or is being rejected by Japanese networks after initial attachment. Reinstalling is not possible since the QR code has already been used.
The issue is not related to:
– Device compatibility
– Location (I am in Japan)
– Incorrect settings
– Lack of network coverage
At this point, the eSIM is completely unusable.
Please advise one of the following:
1) Re-provisioning or replacement of the eSIM profile, or
2) A refund, as the service cannot be used as advertised.
I am happy to provide order details or screenshots if needed.
Best regards,
Jonas

very similar price to a WiFi hotspot unless the WiFi hotspot is being used for many people. Connection was mostly 4G in the Central Japan area. Receiving and sending were fast, including photos and videos. One suggestion, particularly for first time users if they are not really smart phone savvy is to have a “one page” pdf instruction sheet summary that can be downloaded from how to order, activate and then disconnect when returning home. The information is all on the website but in different places. I created my own one page instruction sheet that I will share with friends who want to try an eSIM. I’m switching over from using a WiFi hotspot to eSIM for future trips. thank you.
Thank you so much for sharing your detailed and thoughtful review!
We’re glad to hear that you found the connection reliable in Central Japan and that data speeds worked well for sharing photos and videos. It’s also great to know that the eSIM experience has encouraged you to switch from a WiFi hotspot for your future trips.
