Terms of Service

1. Acceptance of Terms

Welcome to co:sim, operated by Comsand Inc., a Delaware corporation with its registered office at 800 N King Street, Wilmington, DE 19801, United States (hereinafter referred to as "we" or "the Company"). By using our services, you agree to comply with these Terms of Service. If you do not agree to these terms, please do not use our services.

2. Language and Interpretation

These Terms of Service, along with our Privacy Policy, Refund Policy, and Cookie Policy, are provided in English as the authoritative version. Any translations of these legal documents into other languages are provided for convenience only. In the event of any discrepancy, inconsistency, or ambiguity between the English version and any translated version, the English version shall prevail and govern.

3. Service Description

co:sim provides two main eSIM services:

4. User Responsibilities

When using our services, you agree to:

• Provide accurate and complete personal information
• Ensure your device supports eSIM and is unlocked (see our Supported Devices)
• Not use the service for any illegal purposes
• Not resell or transfer your purchased eSIM
• Comply with laws and regulations of destination countries
• Safeguard your account information and balance

5. Purchase & Payment

All prices are displayed in US Dollars (USD). We accept the following payment methods:

• Credit/Debit Cards (Visa, Mastercard, American Express, UnionPay, JCB)
• Apple Pay, Google Pay
• Alipay, WeChat Pay
• Amazon Pay
• Crypto and stablecoin payments (USD only)

Payment methods are shown at checkout based on your region, currency, device, and order eligibility. After successful payment, you will receive an email containing your eSIM QR code. All transactions are securely processed by Stripe.

6. Validity & Data

7. Service Limitations

• Data Only eSIMs provide data connectivity only, excluding voice calls and SMS
• The ONE card is data-only: no phone number, no SMS and no traditional voice calls
• Network speed and coverage depend on local carrier conditions; we cannot guarantee specific speeds or 100% coverage
• eSIMs can typically only be installed once; reinstallation may not be possible after deletion
• Some countries/regions may have special usage restrictions

8. Refund Policy

Uninstalled eSIMs can be refunded unconditionally within 30 days of purchase. Once installed on your device, eSIMs cannot be refunded unless there is a technical issue on our side; this does not affect statutory consumer rights that cannot be excluded. See our Refund Policy for details.

Each Data-Only eSIM plan has a pre-installation validity window. You must install (scan) the eSIM and activate it by connecting to a network before this deadline, or the profile expires permanently — installing it alone is not enough. An eSIM that has expired without being activated is not eligible for a refund. See Refund Policy §10 — eSIM Pre-Installation Validity for full details.

9. Account Security

You are responsible for protecting your account security, including:

• Using a secure email address
• Not sharing your login credentials
• Notifying us immediately of any unauthorized use
• Being responsible for all activities under your account

Deleting your account

You may request deletion of your account at any time from Account → Delete account. The request takes effect 30 days after you submit it. During those 30 days you can cancel it using the banner shown at the top of every page while signed in; simply signing in does not cancel it.

When deletion takes effect, all eSIMs associated with the account permanently stop being accessible, including any unused data and any remaining validity. It is your responsibility to save your QR codes and ICCIDs before the deletion date. We cannot restore access afterwards, and no compensation is offered for eSIMs lost this way.

Deleting your account is not a refund request and does not extend, pause, or preserve any refund window. If you are entitled to a refund under Section 8, claim it before your account is deleted — the self-service refund is only available from a live account.

We retain transaction records after deletion where accounting, tax, or fraud-prevention obligations require it, as described in our Privacy Policy. Promotional and one-per-customer limits you have already used remain in force if you later create a new account with the same email address.

10. Disclaimer

This service is provided "as is." We are not liable for:

• Service unavailability due to device incompatibility
• Local carrier network outages or speed issues
• eSIM damage or loss due to user error
• Any indirect, incidental, special, or consequential damages

11. Terms Modification

We reserve the right to modify these Terms of Service at any time. Modified terms will be published on our website, and continued use of the service constitutes acceptance of the modified terms. Significant changes will be notified via email.

12. Governing Law

These Terms of Service are governed by the laws of the State of Delaware, United States, without regard to its conflict of law provisions. Any disputes arising from these terms or our services shall be subject to the exclusive jurisdiction of the state and federal courts located in Delaware, United States.
