Terms of Service

1. About these terms

These terms govern your use of the DeSIM platform — browsing plans, funding a balance, buying eSIM data plans, and installing the profiles we issue. By creating an account or buying a plan, you agree to them.

We may update these terms. The date at the top of this page shows when they last changed, and continuing to use the platform after a change means you accept the revised version.

2. Your account and key

DeSIM accounts have no email address and no password. When you register we generate a single key, show it once, and never show it again. That key is the only way into your account.

We store a hashed form of your key, not the key itself, so we cannot recover it, reset it, or tell you what it is. Keeping it safe is entirely your responsibility.

Anyone holding your key can access your account, spend your balance and use your plans. Treat it as you would a password to a payment account, and rotate it in settings if you believe someone else has seen it.

You are responsible for everything done through your account. You must be old enough to enter a contract where you live, and you must not share, resell or transfer your account.

3. Plans, data and validity

We sell prepaid mobile data plans delivered as eSIM profiles. Plans are data-only: they carry no phone number and cannot make calls or send SMS.

A plan's clock starts when the eSIM first connects to a network and uses data at your destination — not when you buy it, and not when you install it. You can buy and install well in advance without losing validity.

A plan ends when its validity period expires or its data allowance is used up, whichever happens first. Stated durations are a maximum, not a guarantee of how long the data will last.

Speeds, coverage and network availability depend on the local operators we work with and are outside our control. We do not guarantee any particular speed, uninterrupted service, or coverage at a specific location.

Your device must support eSIM and be carrier-unlocked. Some models — including iPhones sold in Mainland China, Hong Kong and Macao — cannot use an eSIM at all. Checking compatibility before you buy is your responsibility, and we publish a device list for that purpose.

4. Payment and balance

Funds you add are held as a balance denominated in the currency shown in your account, and are spent when you buy a plan. Balances are not a deposit account, earn no interest, and are not transferable between accounts.

We accept card payments and several cryptocurrencies. Crypto deposits are credited once the network confirms them to the required depth, which is shown before you pay.

For crypto payments you must send the exact amount to the address we generate, including any memo or tag the network requires. We cannot credit or recover funds where:

• the payment is sent to an address not generated for that deposit
• the payment is sent on a different network from the one selected
• a required memo or tag is omitted
• an unsupported asset is sent

A deposit shown as expired only means we have stopped actively watching for it. A payment that arrives later is still credited to your balance in full.

Prices are shown before you confirm a purchase and include any fees we charge. Network fees charged by a blockchain are yours to pay and are shown separately where we can calculate them.

5. Refunds

If we cannot issue an eSIM after you have paid — because our provider fails or is unavailable — the purchase price is returned to your DeSIM balance automatically. You do not need to ask.

Where an order cannot be confirmed either way, we hold it and reconcile it against the provider rather than guessing. If it turns out no eSIM was issued, you are refunded.

Because an eSIM profile is a digital good delivered immediately and can generally only be installed once, we do not otherwise offer refunds on issued plans. This includes plans you decided not to use, installed on an incompatible device without checking, or did not consume in full.

Nothing here removes rights you have under consumer law where you live. If those rights give you more than this section does, they apply.

Balances are spendable on the platform and are not redeemable for cash.

6. Acceptable use

You agree to use the service lawfully and not to:

• use it for anything illegal where you are, or where the eSIM is used
• resell, sublicense or commercially redistribute plans without our written agreement
• attempt to bypass usage limits, tamper with profiles, or interfere with the service or its infrastructure
• use automated means to create accounts, or create accounts to abuse promotions or trials
• use the service in a way that breaches a local operator's terms or damages their network

We may suspend or close an account that breaches these terms, and may withhold a balance where we reasonably suspect fraud or unlawful activity while we investigate.

7. Service availability

We aim to keep the platform available but do not guarantee uninterrupted access. Maintenance, provider outages, and network problems outside our control can all interrupt service.

We may change, add or withdraw plans and destinations at any time. Withdrawing a plan does not affect one you have already bought.

8. Your data

We collect the minimum needed to run the service. There is no email address on your account, and we do not ask for a name or address to buy a plan.

Operational logs — webhook deliveries, background jobs and idempotency records — are kept for 30 days and then deleted.

Accounts that are never funded and go unused are deleted after 30 days of inactivity. Signing in before then keeps the account.

Financial records — your balance history, purchases and orders — are retained for as long as we are required to keep them, and are not deleted on a timer. This is a legal obligation, not a choice.

Our privacy policy sets out what we collect and why in more detail.

9. Liability

We provide the service with reasonable care and skill. To the extent the law allows, we are not liable for indirect or consequential loss — including lost profit, lost data, missed connections, or costs arising from being unable to connect while travelling.

Where we are liable, our total liability for any claim is limited to the amount you paid for the plan the claim relates to.

Nothing in these terms excludes liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be excluded.

We are not responsible for your device, its configuration, or charges from your own mobile carrier — including roaming charges incurred because data roaming was left enabled on your home line.

10. Closing your account

You can close your account at any time from settings. Closing it forfeits any remaining balance, which is not refundable in cash.

We may close an account that breaches these terms, or where we are required to by law. Where we do so without cause, any remaining balance is returned to you.

11. General

These terms are governed by the laws of Costa Rica, and the courts of Costa Rica have jurisdiction over any dispute — without affecting any right you have to bring a claim where you live.

If a clause is found unenforceable, the rest of these terms continue to apply.
