Termos e Condições

Last updated: October 25, 2026 · Effective date: October 25, 2026

These Terms of Use (the "Terms") are a binding agreement between you and Onesim LLC ("Onesim", "we", "our", "us"). They apply to every way you use Onesim: the website at onesim.co, the Onesim web app at app.onesim.co (including when it is opened inside another app), the Onesim mobile apps for iOS and Android, our customer support and any related services (together, the "Services"). The same Terms apply on every platform.

By creating an account, placing an order or otherwise using the Services, you agree to these Terms and acknowledge our Privacy Policy. If you do not agree, do not use the Services.

1. Who We Are

The Services are operated by Onesim LLC, 1209 Mountain Rd Pl NE, Suite R, Albuquerque, New Mexico 87110, USA. Email: hello [at] onesim [dot] co.

2. Eligibility and Accounts

• You must be at least 13 years old to use the Services. If you are under the age of majority where you live, you may use the Services only with the involvement and consent of a parent or legal guardian, who accepts these Terms on your behalf and is responsible for any purchase.
• You can sign up with an email address, Sign in with Apple, Google Sign-In or another sign-in method we offer. If you use the same sign-in on more than one platform, or link your accounts, your orders and eSIMs are available on each of them.
• You must give accurate information and keep your sign-in credentials and devices secure. You are responsible for all activity under your account. Tell us promptly at hello [at] onesim [dot] co if you suspect unauthorized use.
• We may refuse service, or limit the number of orders or payment methods, to prevent fraud or abuse.

3. The eSIM Service

3.1. What we provide

Onesim resells prepaid mobile data plans delivered as eSIM profiles ("eSIMs") and data packages ("plans") for use while travelling. The mobile network service itself is provided by partner network operators and connectivity providers in each destination. Coverage, speed and availability depend on the local operator, your location, your device and conditions outside our control, and may differ from what is shown in the plan description.

3.2. Device compatibility

An eSIM works only on an eSIM-capable device that is not carrier-locked and runs a supported operating system version. Compatibility can also depend on your home carrier, device model and the country where the device was made. Please check the compatibility information shown in the Services before you buy. We are not responsible if a plan cannot be used on an incompatible or locked device.

3.3. Installing and using the eSIM

• To use the plan you may need to turn on data roaming for the eSIM and, where indicated, set the Access Point Name (APN). We are not responsible for a failure to configure these settings.
• An eSIM can usually be installed only once. If you delete an eSIM from your device after it has been installed, it may not be possible to restore or reissue it.
• You are responsible for keeping your eSIM installation details (QR code, activation code and links) confidential. Anyone who obtains them may be able to install and use your eSIM.

3.4. Activation deadline and validity

Each plan must be activated and first used within 60 days of purchase. This applies separately to every plan, including a plan bought with a new eSIM and a top-up added to an existing eSIM. The exact deadline is shown in your account and is set one hour before the end of the 60-day window.

Installing the eSIM does not extend the deadline. A plan activates automatically when the eSIM connects to a supported local network and starts using mobile data. Once a plan is activated or used, its stated validity period and data allowance apply; the activation deadline does not shorten that validity period.

A plan that is still unactivated and unused after its activation deadline may be cancelled and removed from the eSIM. Such a cancellation does not trigger an automatic refund. Any refund request remains subject to Section 5 and applicable law.

3.5. Sharing an eSIM

Some eSIMs can be shared with another person through a share link. Anyone who accepts the link gets access to that eSIM and its plans in their own account. You are responsible for whom you share a link with. Accepting a shared eSIM may require the Onesim mobile app.

3.6. Fair use

Plans described as unlimited may be subject to the speed limits or fair-use thresholds stated in the plan description or applied by the local operator.

4. Prices and Payment

• Prices are set in U.S. dollars. Depending on your location and payment method, our payment processor may show and charge the price in your local currency at a converted rate; your bank or card issuer may charge its own fees.
• Applicable taxes are included or added as shown at checkout.
• Payments are processed by Stripe, Inc. and, where available, through mobile wallets such as Apple Pay and Google Pay. Some platforms offer additional payment methods, which are shown at checkout. We do not store your full card number or security code.
• Payments for plans are made directly to Onesim, not through an app store's in-app purchase system.
• When you pay, you authorize us and our payment processor to charge the selected payment method, and you confirm that you are entitled to use it.
• We may correct obvious pricing errors, even after an order is placed. If we do, we will offer you the choice to continue at the correct price or cancel with a full refund.
• Promo codes, discounts, referral rewards and guarantee programs (such as a best-price or money-back guarantee) are subject to the conditions shown with them. They have no cash value and may be withdrawn if obtained or used improperly.

5. Cancellation and Refunds

You may request a full refund for a specific plan within 60 days of payment if the plan is still unactivated, has no start time, shows zero verified usage, and the connectivity provider allows us to cancel it and credit our balance within its own refund window. Installing an eSIM alone does not activate a plan. You must own the order and the plan.

Before cancelling, we show you the plan, amount and currency and ask you to confirm. Cancellation permanently removes that plan from the eSIM. Refunds are returned to the original payment method (for digital-currency payments processed by Stripe, to the original wallet). A refund is complete only when the payment processor confirms it; pending refunds and failed or uncertain cancellations are checked and reconciled by our team.

Activated or used plans, orders for which no eSIM was issued, partial refunds, payments made by methods other than Stripe and any unclear case are reviewed individually by our support team.

Because payments are not processed by Apple or Google, refund requests must be made to us through the Services or at hello [at] onesim [dot] co. Nothing in this section limits any rights you have under mandatory consumer protection law.

6. Customer Support

Support is available in the Services and by email. Our in-app support chat uses an AI assistant that can answer questions, diagnose eSIM issues, check orders and prepare eligible refunds. The assistant can make mistakes; you can ask for a human operator at any time. A refund prepared by the assistant is made only after your separate, explicit confirmation and remains subject to Section 5. Please do not send passwords, full card numbers or unrelated sensitive information in support messages.

7. Acceptable Use

You agree to use the Services only for lawful purposes and in line with these Terms. You must not:

• use the Services for fraud, including card testing or using payment methods you are not authorized to use;
• abuse promotions, referral programs, guarantees or refunds, for example by creating multiple accounts;
• resell eSIMs or plans, or offer them commercially, without our written permission;
• use the network service in a way that harms the network, other customers or the operator, including spam, malware, attacks or excessive automated traffic;
• copy, reverse-engineer, scrape or interfere with the Services, bypass security or rate limits, or access them by automated means other than those we provide;
• use the Services in violation of the laws of the country where you use them.

If you breach these Terms, we may suspend or cancel the affected order or account. Where the breach involves fraud or abuse, we may decline a refund to the extent permitted by law.

8. Account Closure

You may stop using the Services at any time and may delete your account in the account settings of the website or mobile app, or by emailing hello [at] onesim [dot] co. Deleting your account does not cancel or refund plans that are already active, and data we must keep by law is retained as described in the Privacy Policy. We may suspend or close an account that breaches these Terms or that has been inactive for a long time, after giving notice where practical.

9. App Stores and Third-Party Platforms

You may access the Services through third-party platforms, such as app stores, browsers, other apps that can open the Onesim web app, and payment providers. Your use of those platforms is governed by their own terms and privacy policies, and they are not responsible for the Services.

If you downloaded an Onesim mobile app from the Apple App Store:

• these Terms are between you and Onesim only, not Apple, and Onesim (not Apple) is solely responsible for the app and its content;
• your license to use the app is limited to Apple-branded devices that you own or control, as permitted by the Usage Rules in the App Store Terms of Service;
• Apple has no obligation to provide maintenance or support for the app;
• if the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app, if any; to the maximum extent permitted by law, Apple has no other warranty obligation regarding the app;
• Onesim, not Apple, is responsible for addressing any claims relating to the app, including product liability claims, claims that the app fails to meet legal or regulatory requirements, and consumer protection or privacy claims;
• if a third party claims that the app or your use of it infringes their intellectual property rights, Onesim, not Apple, is responsible for the investigation, defense, settlement and discharge of that claim;
• you confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties;
• you must comply with any applicable third-party terms when using the app;
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

If you downloaded an Onesim mobile app from Google Play, Google is not a party to these Terms and is not responsible for the app.

10. Intellectual Property and License

The Services, including the apps, website, software, design, text and trademarks, belong to Onesim or its licensors. Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to use the Services for your own non-commercial purposes. Feedback you send us may be used to improve the Services without obligation to you.

11. Disclaimers

We work to keep the Services available and the network service reliable, but both depend on network operators and other providers we do not control. To the extent permitted by law, the Services are provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not guarantee uninterrupted coverage, specific speeds or that the Services will be error-free.

12. Limitation of Liability

To the extent permitted by law, Onesim is not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, data, business or goodwill, arising from or related to the Services. Our total liability for any claim relating to the Services is limited to the amount you paid for the order that gave rise to the claim. These limitations do not apply to liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, or for fraud.

13. Indemnity

To the extent permitted by law, you agree to indemnify Onesim against third-party claims and related costs arising from your breach of these Terms or your misuse of the Services.

14. Governing Law and Disputes

Please contact us first at hello [at] onesim [dot] co; most issues can be resolved quickly through support. These Terms are governed by the laws of the Republic of Kazakhstan. Any dispute that cannot be resolved by negotiation may be submitted to the exclusive jurisdiction of the Almaty City Court, Almaty, Kazakhstan. If you are a consumer, this does not deprive you of the protection of mandatory provisions of the law of the country where you live, or of your right to bring a claim in its courts where that law allows.

15. Changes to the Services and These Terms

We may change or discontinue parts of the Services. We may also update these Terms; the "Last updated" date above shows when they last changed. If a change is material, we will tell you in the Services or by email before it takes effect. Changes do not apply to orders already placed. If you continue to use the Services after the changes take effect, you accept the updated Terms.

16. General

These Terms, together with the Privacy Policy and any conditions shown at checkout, are the entire agreement between you and Onesim about the Services. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not transfer your rights under these Terms without our consent; we may transfer ours in connection with a merger, acquisition or sale of assets.
