Legal & Policy

Terms of Service

Welcome to Polaris eSIM. By using this service, you agree to comply with the following terms and conditions.

1 Service Description

Polaris eSIM (hereinafter "the Service") is operated by Neutron Star Technology Inc. (Tax ID: 83114084), providing eSIM digital communication services worldwide. Through partnered carriers' Local Network networks, the Service delivers overseas mobile data plans to its users.

After purchasing an eSIM plan through this platform, users will receive a QR Code, which can be scanned and installed on compatible devices to activate internet services.

2 Account and Eligibility

  • You must be at least 18 years old or have full legal capacity to use the Service. Minors must obtain consent from a legal guardian before use.
  • You are responsible for maintaining the security of your account; the Company assumes no responsibility for damages resulting from the leakage of account passwords.
  • Use of the Service for any illegal purposes, including but not limited to fraud, distribution of malware, or infringement of others' rights, is strictly prohibited.

3 Payment and Billing

  • All product prices are subject to the display on the platform page. The company reserves the right to adjust prices at any time; orders completed before the adjustment will not be affected.
  • Upon successful payment, the system will automatically send the eSIM QR Code to your email address. Please ensure that your email address is correct.
  • The company shall not be liable for any losses resulting from the inability to receive the QR Code due to an incorrectly entered email address.

4 Service Usage Guidelines

  • Each eSIM QR Code can only be installed on one device. Once scanned and bound, it cannot be transferred to another device.
  • The validity period of the eSIM plan starts from the time of activation. Any remaining data after expiration will automatically become invalid and will not be extended or refunded.
  • This service is subject to the Fair Usage Policy (FUP). Excessive use (such as long-term streaming or large downloads) may result in speed reduction or disconnection.
  • Hotspot sharing functionality depends on the plan; some plans may not support it or may limit hotspot speeds.

5 Intellectual Property Rights

All content on this platform (including but not limited to text, images, trademarks, code, and interface design) is owned by Neutron Star Technology Inc. or used under legal authorization. Unauthorized copying, modification, distribution, or any form of commercial use is prohibited without written consent.

6 Membership Subscription Service

  • The platform offers three membership tiers: Standard (free; 1% store credit on card purchases), Gold (NT$500/month; 2.5% rewards; 500 store credit added each period), and World (NT$1,500/month; 5% rewards; 1,500 store credit each period). Annual billing charges 11 months of fees for 12 months of membership, with 12 months of store credit added at once upon successful payment. Rewards are calculated only on amounts actually charged to your card; portions offset by store credit are excluded.
  • For credit-card subscriptions, your saved card will be charged automatically at the end of each membership period to renew, until you cancel. Annual subscriptions paid via Apple Pay or Google Pay do not auto-renew and end automatically upon expiry.
  • You may cancel anytime from your account page. Cancellation stops future charges; fees already paid for the current period are non-refundable and benefits remain until the end of the current period.
  • If a renewal charge fails, we will retry daily during a 7-day grace period and notify you by email. If payment still fails when the grace period ends, the membership terminates automatically and reverts to Standard.
  • Upgrades (e.g., Gold to World) take effect immediately upon payment: the full fee of the new tier is charged at once and a new membership period starts that day; the remainder of the original period is neither refunded nor prorated. Downgrades take effect at the next billing; current-period benefits are unaffected.
  • One store credit offsets NT$1 and may only be used to offset purchases on this platform; it cannot be exchanged for cash, refunded, or transferred. When an order is refunded, reward credit granted for that order will be reclaimed in proportion to the refund.
  • We reserve the right to adjust membership plans, fees, and reward rates; changes take effect after announcement and do not affect the benefits of any period you have already paid for.

7 Disclaimer and Limitation of Liability

  • The company does not guarantee that the service will be completely uninterrupted or error-free. The company shall not be liable for compensation when service interruptions are caused by force majeure factors (such as natural disasters, war, damage to telecommunications equipment, changes in government laws, etc.).
  • The maximum liability of the company shall be limited to the amount paid by the user for the specific transaction and shall not include any indirect damages, loss of business, or compensation for mental distress.
  • The network quality, speed, and coverage of mobile data are affected by local telecommunications infrastructure. The company does not provide a minimum guarantee in this regard.

8 Amendment of Terms

The company reserves the right to modify these Terms of Service at any time. The modified terms will be posted on this page without further individual notice. Your continued use of the service constitutes agreement to the modified terms. We recommend that you check this page regularly for the latest regulations.

9 Governing Law and Jurisdiction

The interpretation and application of these terms shall be governed by the laws of the Republic of China (Taiwan). For any disputes arising from these terms, both parties agree that the Taiwan Taipei District Court shall be the court of first instance.
