Very good eSIM I recommend it for everyone
Good Value for Money
Thank you so much for your feedback!
We’re thrilled to hear you enjoyed the eSIM and found it great value. We really appreciate your recommendation and look forward to supporting you on your future trips.
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
