If you are facing any problem, please don’t delete your eSIM plan – instead, contact us via [email protected] first.

Does the plan provide a local phone number?

eSIM Japan provides data-only plans. Therefore, a local phone number is not included in the plans. As a result, making calls and sending SMS are unavailable.

When you arrive at your destination, please check the following below, so that you can use your data successfully.
Also, please don’t remove the plan since it can’t be reissued or reinstalled after deleting the eSIM.

After you arrived at your desination, please check the following :

B. Reset the network connection & Restart your device.

Reset the network connection by turning on Airplane Mode for 15 seconds and turning it off again.
