When using an eSIM during your trip to Japan, many people feel anxious about accidentally deleting it or wondering, "Will it stop working if I delete it?"
Unlike physical SIM cards, eSIMs may not be easily restored once deleted from your smartphone. Therefore, it is important to understand the precautions before deleting.
In this article, we will explain in detail what happens when you delete a Japan eSIM, how to deal with it afterward, and the points you should check before deletion.

What happens when you delete a Japan eSIM?
When you delete an eSIM, the eSIM profile is removed from your smartphone.
After deletion, you may not be able to use that eSIM anymore. Some products cannot be reinstalled, so it is not advisable to delete it lightly.
| After Deletion | Status |
|---|---|
| eSIM Profile | Deleted |
| Communication | Unavailable |
| Reinstallation | Varies by product |
| QR Code | May not be reusable |
Can it be reused after deletion?
It varies by product.
Some eSIMs can be reinstalled using the same QR code, but there are also products that cannot be reused once deleted.
Please check the usage conditions of the eSIM provider to see if reinstallation is possible.

What to do if you accidentally delete it
- Check the email received at the time of purchase
- Confirm if the QR code can be reused
- Contact the provider
- If necessary, purchase a new eSIM
Rather than repeatedly setting it up on your own, it is recommended to first consult the provider's support.
Things to check before deletion
- Is your trip over?
- Is there any remaining usage period?
- Is it a product that can be reinstalled?
- Have you saved the QR code?
- Have you checked the support information?
If you are still traveling, be careful not to delete the eSIM as it may result in loss of communication.

Precautions when deleting an eSIM
Before deleting an eSIM, checking a few things can help prevent communication troubles and the hassle of reconfiguration.
- Do not delete while traveling
- Check if there is any remaining usage period
- Check if reinstallation is possible
- Save the QR code and order email
- Review the provider's instructions before deletion
Especially if you delete it while traveling, you may lose immediate internet access. If deletion is necessary, follow the provider's instructions.
