1. Introduction

This eSIM Usage Policy (“Policy”) governs the use of eSIM services provided by Flystar (“Flystar”, “we”, “us”, “our”), a brand operated by Combo International (Hong Kong) Co., Limited.

2. Device Compatibility

Customers are solely responsible for ensuring that their device:

  • Supports eSIM technology;

  • Is carrier-unlocked;

  • Is compatible with the selected destination and network;

  • Meets any technical requirements stated on our website.

Flystar does not guarantee compatibility with every device model.

Refunds will not be granted for compatibility-related issues where the device does not meet these requirements.

  • Following activation instructions;

  • Maintaining access to the activation email;

  • Completing setup on a compatible device.

An eSIM profile is generally intended for installation on a single device.

Flystar is not responsible for service interruptions caused by incorrect installation, accidental deletion, factory resets, or device changes.

4. Service Coverage

Flystar partners with mobile network operators worldwide to provide connectivity services.

Coverage depends on:

  • Local network availability;

  • Geographic location;

  • Device capabilities;

  • Network congestion;

  • Government restrictions;

Service quality may vary by destination.

5. Data Usage

Each eSIM plan includes a specific:

  • Coverage area.

Customers are responsible for monitoring their own data usage.

Once a data allowance is exhausted, service may:

  • Stop automatically;

  • Be reduced in speed;

  • Require a top-up purchase.

Unused data generally expires when the plan validity period ends and is not refundable, transferable, or redeemable for cash.

6. Fair Usage Policy (FUP)

To ensure network stability and service quality for all users, Flystar and its network partners may apply Fair Usage Policies.

Users may experience:

  • Reduced speeds;

  • Temporary restrictions;

  • Network management measures;

if usage patterns are deemed excessive, abnormal, or harmful to network performance.

Flystar reserves the right to take reasonable actions to protect network integrity.
