The Service is provided using Telecommunications Providers, Compatible Networks, eSIM profile providers, payment service providers, cloud service providers, and other third-party services with which the Company cooperates or which the Company uses.

The countries or regions where the Service is available are those displayed by the Company on its website, application, purchase screen, or by other methods. Even within a covered country or region, the Service may be unavailable due to Telecommunications Providers, Compatible Networks, communication regulations, devices, radio conditions, outages, maintenance, or other circumstances.

Mobile data connection availability, coverage, speed, quality, Compatible Networks, and stability in each country or region may vary depending on the terms, facilities, frequency bands, roaming settings, network congestion, local regulations, location, device, radio conditions, and other circumstances of local Telecommunications Providers or Compatible Networks.

The Company may change the content, specifications, Telecommunications Providers, technology, covered countries or regions, Compatible Devices, and other conditions of the Service as necessary for business, technical, legal, or operational reasons, in accordance with Articles 11 and 16.

Article 4 (Account)

To use the Service, a User must create an Account by the method specified by the Company or receive an Account from the Company.

A User must provide true, accurate, and up-to-date information when registering an Account or making a purchase.

A User must manage the Account, authentication information, email address, login method, and other information necessary to use the Service at the User's own responsibility.

The Company is not liable for damage arising from Account mismanagement, third-party use, incorrect input, inability to receive email, or other matters attributable to the User's management, except where caused by the Company's willful misconduct or gross negligence.

A User must not transfer, lend, sell, change the name of, pledge, or otherwise dispose of the Account to or for a third party.

If a minor purchases or uses the Service, the minor must obtain consent from a parent, guardian, or other legal representative.

If a User deletes the Account, the Stork Mobile eSIM linked to that Account will expire, and unused Data Plans, data allowances, and other usage rights under the Service will no longer be available. In that case, the Company will not provide refunds, compensation, or alternatives, except where required by law.

Article 5 (eSIMs and Data Plans)

Stork Mobile eSIMs are provided to Users by the method specified by the Company. A Stork Mobile eSIM may be issued when a User first purchases a Data Plan on the website.

A Stork Mobile eSIM must be installed and used on a Compatible Device used by the User.

After a Stork Mobile eSIM is installed on a device, it may not be transferable, reusable, or reissued for another device.

The User is responsible for managing the QR code, activation code, SM-DP+ address, and other setup information for eSIM installation.

QR codes and other eSIM setup information may be usable only once. The User must install the eSIM in a stable communication environment and in accordance with the guidance of the Company or the device manufacturer.

If an eSIM becomes unavailable because the User deletes the eSIM, changes devices, loses or damages a device, resets a device, or for any other reason on the User's side, the Company will not reissue the eSIM or provide refunds, compensation, or alternatives, except where required by law.

A Stork Mobile eSIM under the Service is valid for 730 days from the last usage date of that eSIM. A Stork Mobile eSIM that has passed 730 days from its last usage date will expire and become unavailable.

The last usage date under the preceding paragraph is based on communication usage records acquired, recorded, or determined by the Company or its partners. It may differ from device displays, Telecommunications Provider displays, or the User's understanding.

A Data Plan may be used as long as the Stork Mobile eSIM to which the Data Plan is linked remains valid. If the Stork Mobile eSIM expires, is deleted, suspended, or disabled, any unused Data Plan or data allowance will also become unavailable.

Data Plan activation, consumption, remaining balance, usage history, and other status information are determined based on communication usage records acquired by the Company or its partners.

Data usage, remaining data, usage history, and other information displayed in the Service are based on information obtained from Telecommunications Providers or other third parties or on calculations in the Company's systems and may differ from information displayed on the device.

In connection with changes to the communication platform, eSIM provision method, or other specifications or operations of the Service, the Company may provide Users who use Stork Mobile eSIMs or Data Plans provided before the effective date of these Terms with Stork Mobile eSIMs, Data Plans, data allowances, or other alternatives necessary for migration. The eligible Users, migration timing, treatment of the pre-migration Stork Mobile eSIMs or Data Plans, data allowances to be provided, and other conditions will be governed by migration conditions separately announced by the Company.

To use the Service, the device must support eSIM, must not be SIM-locked, must support the communication methods and frequency bands of the country or region of use, and must satisfy the necessary OS version and other conditions specified by the Company.

Depending on the device, country, region, Telecommunications Provider, Compatible Network status, or other conditions, APN settings, data roaming settings, network selection, or other settings may be required to use the Service.

If the Service cannot be used due to the device not being a Compatible Device, the device being SIM-locked, insufficient device settings, OS or device specification issues, device failure, or other matters attributable to the User's device or settings, the Company will not provide refunds, compensation, or alternatives, except where required by law.

Article 7 (Fees and Payment)

Service fees will be displayed on the purchase screen or by another method specified by the Company.

Service fees are payable in U.S. dollars, Japanese yen, or any other currency and amount displayed by the Company on the purchase screen or similar interface.

A User must pay Service fees using a payment method specified by the Company.

Payment processing may be performed through a payment service provider or other third-party service used by the Company.

The Company may acquire or store payment results, transaction identifiers, card brands, partial card numbers, and other information necessary for payment management from payment service providers, but the Company does not store complete card numbers or security codes in its systems.

Fees, foreign exchange differences, conversion rates, billing dates, debit dates, and other conditions may arise or change due to foreign exchange, card companies, payment service providers, financial institutions, or other third parties. The Company is not responsible for those matters.

A User must enter payment information accurately and use a payment method for which the User has proper authority.

If payment problems occur, including unauthorized payment, unauthorized use, chargebacks, payment refusal, or payment failure, the Company may suspend the Service, suspend the Account, suspend the eSIM, cancel the purchase, or take other necessary measures.

Article 8 (Cancellation and Refunds)

The Service is a service that begins to be provided when the eSIM is issued, the Data Plan or data allowance is granted, payment is completed, or other processing specified by the Company is completed.

The Company generally does not provide cancellations, refunds, exchanges, reissuance, compensation, or alternatives after purchase for reasons attributable to the User, regardless of the reason.

Reasons attributable to the User under the preceding paragraph include the Service being unused, no longer needed, changes or cancellation of travel plans, the device not being a Compatible Device, the device being SIM-locked, inability to configure device settings, dissatisfaction with communication quality or speed, deletion of the eSIM, device change, loss, failure, or reset, purchase error, and other circumstances on the User's side.

For Data Plans, data allowances, unused data, unused periods, and other usage rights under the Service, the Company will not provide refunds, prorated calculations, cash conversion, transfers, carryovers, or alternatives, except where required by law.

If the Service is not provided due to the Company's willful misconduct or gross negligence, or if refunds or other measures are required by law, the Company will take necessary measures in accordance with the law.

If a refund is provided, the method, currency, amount, processing timing, and other conditions will be reasonably determined by the Company in accordance with applicable laws and the rules of the payment service provider.
