Last updated: September 27, 2025

1. Introduction and Acceptance

JaJapan eSIM ("we," "our," or "us") provides this website and eSIM services subject to the following Terms and Conditions ("Terms"). By accessing our website or purchasing our eSIM products, you agree to be bound by these Terms.

If you do not agree with these Terms, please do not use our services or make any purchases.

2. Service Description

JaJapan eSIM provides prepaid mobile data services through embedded SIM (eSIM) technology for use in Japan. Our services include:

  • Unlimited data plans for various durations (3, 7, 15, and 30 days)
  • Digital delivery of eSIM activation codes via email
  • Access to KDDI's 5G network in Japan
  • Customer support for activation and technical issues

Our eSIM services are data-only and do not include voice calling or SMS messaging capabilities.

3. Eligibility and Device Requirements

To use our services, you must:

  • Be at least 18 years old or have parental consent
  • Own an eSIM-compatible device that is unlocked
  • Provide accurate and complete information during registration
  • Have a valid email address for service delivery

You are responsible for verifying that your device is compatible with our eSIM technology before purchase.

4. Purchase and Payment Terms

All purchases are processed securely through our payment providers. By making a purchase, you agree to:

  • Pay all charges associated with your purchase
  • Provide accurate billing information
  • Accept that prices are subject to change without notice

We accept major credit cards and other payment methods as displayed during checkout. All prices include applicable taxes.

5. Service Activation and Usage

Upon successful payment, you will receive eSIM activation details via email. Please note:

  • eSIM activation codes can only be used once and cannot be transferred between devices
  • Your data plan countdown begins when you connect to the network in Japan
  • You must enable data roaming for the eSIM to function properly
  • Service is limited to use within Japan's geographic boundaries
  • Fair usage policies apply to prevent network abuse

6. Refund and Cancellation Policy

We do not offer refunds once an eSIM has been issued and delivered to your email. All sales are final.

This policy exists because:

  • eSIM codes are digital products that cannot be returned
  • Once delivered, the eSIM activation code has been provisioned for your use
  • eSIM plans costs are carried by us and cannot be refunded

We strongly recommend verifying device compatibility and plan requirements before purchase. If you experience technical issues with activation, please contact our support team for assistance.
