Terms of Service

These Terms of Service ("Terms") apply to every purchase made on voasim.com and to the use of any VoaSim eSIM. By placing an order you confirm that you have read and accept these Terms, our Refund policy and our Privacy policy.

1. The service

VoaSim sells prepaid travel eSIMs: digital, data-only mobile plans used abroad through partner mobile networks in the destination country or region. The eSIM does not include a phone number or traditional voice calls and SMS; calls and messages work through internet apps (for example WhatsApp or FaceTime). Your physical SIM can stay in your phone and keep your usual number.

The plan you buy is defined by the destination (country or region), the number of days and the number of eSIMs in the order, as shown at checkout before you pay.

2. Orders, prices and payment

• Prices are shown in US dollars (USD) and the price displayed at checkout is the final price for the plan selected. Your bank or card issuer may apply its own foreign-currency or international fees, which are outside our control.
• Payments are processed by Stripe. VoaSim does not receive or store your full card details.
• A purchase receipt (invoice) is sent to the email address used in the order.
• You must be at least 18 years old, or have the consent of a parent or guardian, to place an order.

3. Device compatibility

The eSIM only works on a device that supports eSIM and is unlocked (not restricted to a single carrier). Compatibility depends on the exact model, the country where it was sold and the carrier lock. Examples of compatible models are listed on our site, but it is your responsibility to confirm that your device is compatible before you buy. If you are not sure, ask us in the chat or at hola@voasim.com before paying and we will check your model with you.

4. Delivery, installation and validity

• The eSIM is delivered by email, with a QR code and installation instructions, once the payment is confirmed. Please check that your email address is correct; we are not responsible for non-delivery caused by an incorrect address supplied in the order.
• You can install the eSIM in advance, at home and on Wi-Fi. The plan's validity starts counting when the eSIM first connects to a network at the destination, and lasts for the number of days purchased.
• To use it at the destination, the eSIM line must be switched on and set as the data line, with data roaming enabled for that line.
• An eSIM can be installed only once and stays on the device where it was installed. Do not delete the eSIM from your device: a deleted eSIM cannot be reinstalled or issued again. If you change phones, transfer the eSIM first using your phone's own transfer option, when available. To stop using it, simply switch the line off.
• Unused days do not carry over after the plan expires.

5. Unlimited data and acceptable use

VoaSim plans are unlimited data plans: we do not sell data allowances, and your plan does not end because you reached an amount of data. To keep the service working well for every traveler, the following rules apply:

• Each eSIM is for the personal use of one traveler, on one device.
• Hotspot and tethering (sharing the connection with other devices) are not allowed; the local network may block a line used this way. Each traveler needs their own eSIM.
• The eSIM may not be resold, used in routers, modems, IoT devices or SIM boxes, used to run servers or automated or continuous bulk traffic, or used for any unlawful purpose, spam, fraud or activity that harms the network or other users.

Speed and coverage depend on the partner network at the destination, the location, network congestion, the device and its settings. Partner networks apply their own network management, and we cannot guarantee uninterrupted service or a specific speed at all times. If your connection is not working as it should, contact us: we will diagnose the issue and, where needed, adjust your plan or issue a new eSIM at no cost.

We may suspend an eSIM that is used in breach of this section, after contacting you whenever possible.

6. Support

Support is available by chat and by email at hola@voasim.com, before, during and after your trip. Our AI assistant answers 24 hours a day, and our human team handles cases that need a person. Please contact us before deleting or reinstalling an eSIM.

7. Connection guarantee, cancellations and refunds

If the eSIM does not connect at your destination and our support cannot fix it, we issue a new eSIM at no cost or refund 100% of what you paid. Cancellations, changes and refunds are governed by our Refund policy, which forms part of these Terms.

8. Your responsibilities

• Provide accurate information in your order (email, destination and travel dates).
• Check device compatibility and follow the installation instructions.
• Keep the QR code and activation details private; anyone who has them may be able to install your eSIM.
• Use the eSIM in accordance with these Terms and the laws of the country where you use it.

9. Limitation of liability

To the fullest extent permitted by law, VoaSim is not liable for indirect or consequential losses, such as lost profits, missed bookings or costs charged by your home carrier (for example roaming charges on your physical SIM if its data roaming is left on). VoaSim is not responsible for interruptions caused by events outside its reasonable control, including network outages of partner carriers, natural disasters, government restrictions or force majeure. In any case, our total liability for an order is limited to the amount you paid for that order.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, or the mandatory rights you have as a consumer under the laws of your country of residence.

10. Intellectual property

The VoaSim name, logo, website content and tools (including eSIM Rescue and the eSIM Price Index) belong to VOASIM LTDA or its licensors and may not be copied or used commercially without permission.

11. Changes to these Terms

We may update these Terms from time to time. The version published on this page on the date of your purchase applies to that purchase.

12. Governing law and disputes

These Terms are governed by the laws of the Federative Republic of Brazil, including the Brazilian Consumer Protection Code (Law 8.078/1990). The courts of Maringá, Paraná, Brazil have jurisdiction, without prejudice to any mandatory consumer protection rules, and the right to bring proceedings in the courts, that apply in your country of residence. Before any formal claim, please write to hola@voasim.com: most issues are solved in the same support thread.
