Terms of Service

The rules for buying and using a Simsimsim eSIM plan, in plain language.

Last updated: 2026-10-15

These terms apply when you use simsimsim.net and when you order an eSIM plan from Simsimsim. If you do not agree with them, please do not place an order. Questions: support@simsimsim.app.

1. The service

Simsimsim sells prepaid, data-only eSIM plans for use abroad. A plan gives you mobile data on partner networks in the countries or regions named on its product page. It does not include a phone number or voice calls. The data amount, validity period, countries and any speed limits are shown on the plan page and in your order, and they are what we owe you.

Online payment on the site is still being finished. These terms apply once ordering is available.

2. Your phone

You are responsible for checking that your phone supports eSIM and is not locked to a carrier that blocks other eSIMs. See Does my phone support eSIM? and the compatible devices list. Each eSIM can be installed on one device.

3. Coverage and speed

Coverage and speed depend on the local mobile operators, your location, your phone and network congestion. We list the operators and network type (4G or 5G) for each destination, but we cannot promise a specific speed or coverage in every place. Where a plan has a daily full-speed allowance, data continues at a reduced speed after you use it.

4. Orders and payment

Prices are shown in US dollars on the site. Payment is handled by payment processors; we do not see or store your full card number. Crypto payments, where offered, are confirmed on the blockchain before the order is completed. An order is accepted when you receive the eSIM details by email.

5. Delivery

We send the QR code and manual activation details to the email address you enter at checkout, usually within a few minutes of payment. Please check the address before you pay. If the email does not arrive, check spam and then write to us. Treat the QR code like a password: it can be installed once, and anyone who installs it first gets the plan.

6. Validity

An unused plan stays valid for up to 180 days before activation, as stated on the plan page. After activation, the plan runs for the number of days in its description and ends when the days or the data run out, whichever comes first. Where a plan supports top-ups, you can add a plan to the same eSIM while it is active.

7. Refunds

Our refund policy forms part of these terms. In short: a full refund if you never install the eSIM (within 180 days), a full refund if it is installed but never activated (within 30 days), credit only after activation while under 5% of the data is used, and no refund for expired plans or more than 30% of data used. If the eSIM fails to connect because of a fault on our side or no coverage, we refund the plan.

If you live in the EU or UK, you may have a right to withdraw from a distance purchase within 14 days. For digital content that starts to be provided with your consent, this right ends once the eSIM is activated, as described on the refund page. This does not limit rights you have under mandatory consumer law.

8. Fair use

Plans are for personal travel use. Please do not resell plans, use them for unlawful activity, or try to bypass speed limits or country restrictions. We may suspend or cancel an eSIM that is used in a way that harms the network, other customers or us, or that is linked to fraud or repeated abusive refund requests.

9. Liability

We provide the service with reasonable care. Mobile networks are run by third parties, so we are not responsible for outages, roaming restrictions or local regulations outside our control. As far as the law allows, our liability for any claim about a plan is limited to the amount you paid for that plan. Nothing in these terms excludes liability that cannot be excluded by law, and your rights as a consumer under the law of your country stay in place.

10. Changes

We may update these terms. The date at the top shows the latest version. Changes do not affect plans you already bought. If a change is material, we will say so on the site.
