Regional eSIM · 1 day · 3G/4G/5G · hotspot
10 GB in Japan & South Korea · 2 countriesfor 1 days
A prepaid travel eSIM for 2 countries and territories, including Japan, South Korea, carrying 10 GB of data every day for 1 day. It is a data plan: it installs as a second line on a phone that already has one, so your own number stays active for calls and messages and nothing about your home contract changes.

From first connection
Sites see SG, not Japan & South Korea · 2 countries
The eSIM connects to KDDI/au, SKTelecom and LG Uplus. Your phone selects whichever of those is strongest wherever you are standing, in the same way roaming does — there is no network to choose and nothing to switch by hand. Speeds are 3G/4G/5G where the network supports it.
Validity starts the first time the eSIM connects to a network abroad, not when it is bought, so it can be installed at home days before departure without spending any of the 1 day. Tethering and personal hotspot are permitted.
Traffic on this plan exits in SG, so websites and apps see that country rather than Japan & South Korea · 2 countries. This occasionally matters for banking apps and streaming catalogues, and it is stated here rather than discovered later.
Delivery is immediate and by email: a QR code and step-by-step instructions for the specific phone, usually within a minute of payment. The plan does not renew and cannot bill again — when the data or the 1 day run out it simply stops, and more data can be added to the same eSIM without reinstalling it.
Requires an eSIM-capable, carrier-unlocked phone — iPhone XS or newer, Google Pixel 3 or newer, most Samsung Galaxy S20 or newer. An eSIM profile can be installed one time only: deleting it, resetting the phone or erasing all content destroys the plan permanently.
The other 5 Japan & South Korea · 2 countries plans
4 of them cost less than this one. Data you do not use is not refunded, so the smallest plan that covers the trip is usually the right one.
Install once — deleting it destroys the plan
An eSIM profile can be installed one time only. Deleting it from your phone, resetting the device or erasing all content loses this plan permanently — it cannot be reissued and it cannot be refunded. Step-by-step guide for your phone
