Step-by-step
How to buy an eSIM with crypto
Five minutes, one wallet, zero forms. Here’s the exact flow from “no account” to “connected” — and the pitfalls that cost people time.
Before you start
Nothing here is complicated, but each of these three saves you a false start. None of them involve typing your name anywhere — that's the point of the whole no-KYC idea.
- A wallet holding any supported coin: BTC, XMR, ETH, LTC, TRX, SOL or USDT.
- An eSIM-capable, carrier-unlocked phone (dial
*#06#— an EID line means yes). - About $25, the minimum balance top-up.
No wallet yet? Buying a small amount of a coin like USDT or BTC on any exchange and moving it to a personal wallet takes longer than the rest of this guide — budget ten minutes if this is your first time.
The six steps
From a blank browser tab to a working connection, in order:
- 01Create your token
One click, no email, no password. Save the XXXX-XXXX-XXXX-XXXX code somewhere safe: it IS the account.
- 02Open “Add funds”
Pick an amount and a coin. A fresh deposit address is minted for you, never reused, never shared.
- 03Send the exact amount
Copy the amount and address (or scan the QR) from your wallet. Send exactly what's shown.
- 04Wait for confirmation
Tokens like USDT credit in about 2 minutes; on-chain BTC typically needs one confirmation, roughly 10 to 30 minutes.
- 05Pick a destination & pack
Balance in hand, every purchase is one tap — no checkout forms, ever.
- 06Scan your QR
It appears instantly on your dashboard. Install it and you're done.
Most people finish this in under five minutes of active effort — the only variable outside your control is which coin's confirmation you're waiting on. Once the QR is installed, install and activate your eSIM has the exact screens for both iPhone and Android.
Which coin should you pay with?
| Coin | Best for | Speed | Fees |
|---|---|---|---|
| Monero (XMR) | Maximum privacy — untraceable by default | ~10–20 min | Very low |
| Bitcoin (BTC) | You already hold it | ~10–30 min | Network-dependent |
| TRON (TRX) | Speed | ~2 min | Near zero |
| Litecoin (LTC) | Cheap + fast middle ground | ~5 min | Very low |
| USDT | No price volatility | ~2–5 min | Low (pick TRC-20) |
Whatever you send, prices stay in USD — the invoice locks the coin amount for its validity window.
Reading an invoice correctly
Every top-up produces the same four-part invoice, no matter which coin you pick. Knowing what each part is for is most of what prevents a stalled payment.
- The address. Minted fresh for this top-up only — never paste in an address you saved from a previous order.
- The exact amount. Down to the last decimal the wallet shows. Rounding, even generously, reads as an underpayment.
- The countdown. Invoices hold their coin amount for a limited window while prices move; send after it expires and the amount may no longer match.
- The QR code. Scanning it fills in the address and amount for you, which is the safest way to avoid a copy-paste typo on a phone keyboard.
If a wallet app splits “amount” and “network fee” into two numbers, the invoice amount is the first one — the network fee is separate and set by the blockchain, not by us.
Which coin leaves the thinnest trail
All eight coins buy the same product. They don't leave the same paper trail once the transaction is on a public blockchain, which matters if the purchase itself is the thing you'd rather keep quiet.
| Coin | On-chain privacy | Practical note |
|---|---|---|
| Monero (XMR) | Private by default — sender, receiver and amount are all obscured | The closest thing to cash in this list |
| Bitcoin (BTC) | Public and permanent — anyone can trace an address's history | Fine if the wallet itself isn't linked to you elsewhere |
| Litecoin (LTC) | Public, same model as Bitcoin | Faster and cheaper than BTC, same trail |
| Ethereum (ETH) | Public, and addresses often reused across apps | Convenient if you already transact in ETH regularly |
| TRON (TRX) | Public | Chosen mostly for speed and near-zero fees, not privacy |
| Solana (SOL) | Public | Fast confirmation, public ledger like the others |
| USDT (ERC-20 / TRC-20) | Public, and tied to a centralized issuer that can freeze addresses | Picked for price stability, not privacy |
None of this affects us — no order is ever linked to a name on our side regardless of coin. It only affects what a blockchain explorer can show about where your coin came from and went. Paying with Monero goes deeper on why it's the default choice for privacy-first buyers.
What it actually costs
Two different fee lines get confused constantly: what IncognitoSIM charges, and what the blockchain charges to move your coin from your wallet to the invoice address. They aren't the same thing, and only one of them is ours to control.
- The $25 minimum is a top-up floor, not a per-order price — it funds a balance you spend down over several packs.
- Network fees belong to the blockchain, not the store. They rise and fall with how busy that chain is right now, which is why TRX and LTC stay cheap while BTC swings.
- There's no card-processing markup to hide, because there's no card anywhere in the flow.
Prices are quoted in USD on every page; the invoice fixes the coin amount for its validity window so a moving market doesn't cost you extra.
What happens after your balance is funded
Say your top-up has just landed. From here, buying is the part that finally feels effortless:
- 01Pick a destination
Search or browse — Thailand, for example — and pack sizes show against your balance in real time.
- 02Choose a size
1 to 50 GB, each valid for 30 days that start at first connection in the destination, not at purchase.
- 03Get your QR
It's on the dashboard immediately. Install it whenever you like — before the trip is fine, the clock hasn't started.
- 04Top up again anytime
Same balance, same order page, no new identity check the second time either.
Browse all 190 countries to see what's available before you fund the first top-up.
If a payment doesn't confirm
Crypto payments occasionally look stuck, usually for a boring reason rather than a lost one. Before assuming the worst and opening a ticket:
| Symptom | Likely cause | What to do |
|---|---|---|
| Balance hasn't updated after 10+ minutes | Normal for on-chain BTC — confirmations take time | Wait for one confirmation, usually 10 to 30 minutes |
| You sent slightly less than the invoice | Underpayment | Open a support ticket; it gets matched to the order without starting over |
| You sent USDT but on the wrong chain | Network mismatch (ERC-20 vs. TRC-20) | Contact support with the transaction hash — recovery depends on the chain and isn't guaranteed |
| The invoice countdown expired mid-transfer | Timing | Don't send late; start a fresh top-up instead |
Every one of these routes through the same anonymous ticket desk — no email required to get help.
Paying with crypto vs. paying with a card
Most eSIM marketplaces still run a card through a normal checkout, name and billing address included. Here's what changes at each step when the whole flow is crypto instead:
| Step | Card checkout | Crypto balance |
|---|---|---|
| Identity | Name, email, billing address | None — an anonymous token |
| Payment trail | Bank and card network both see it | A blockchain transaction, no bank involved |
| Repeat purchases | Re-enter or store card details | Spend an existing balance, one tap |
| Refund path | Card network dispute process | Reissue or refund in the coin paid |
The trade is speed on the first step for the absence of a paper trail afterward. For most people who've done it once, the crypto step stops feeling slow at all.
The three classic mistakes
Support tickets about a “missing” payment almost always trace back to one of these three.
Do
- Copy the exact amount from the invoice
- Match the network to the coin (USDT-TRC20 ≠ USDT-ERC20)
- Send before the invoice countdown expires
Don’t
- Rounding the amount “to be nice” — underpayments stall
- Sending USDT on the wrong chain
- Reusing an old deposit address from a previous top-up
Questions, answered
What happens if I underpay or the invoice expires?
Nothing is lost. The payment is detected and support can settle it through an anonymous ticket, matched to your order using the token you already hold. Matching the exact amount and sending inside the countdown window just avoids that wait entirely, so it's worth the extra ten seconds of care.
Why a balance instead of paying per order?
One top-up funds many purchases. Packs and top-ups become one tap with no new invoice per order, which matters because network fees don't move in round numbers — a balance absorbs that instead of forcing an odd payment on every single pack you buy.
Is there a card payment fallback?
No, and that's deliberate. Cards drag your bank identity into the loop the moment they touch a checkout page; the whole design goal of paying in crypto is that no such link ever exists, on our side or the bank's.
Which coin is fastest?
TRON and other token transfers typically credit in around 2 minutes. On-chain Bitcoin is the slowest of the eight, usually needing one confirmation, which takes roughly 10 to 30 minutes depending on how busy the network is when you send.
Do I need a crypto wallet already set up?
Yes. You need a wallet holding one of the eight accepted coins before you start. If you're new to crypto, creating a wallet and buying a small amount on an exchange takes longer than the eSIM purchase itself, but it's a one-time step you won't repeat.
Can I top up with a different coin than I used the first time?
Yes. Each top-up is its own transaction with a freshly minted address, so you can mix coins across visits — pay the first top-up in Bitcoin and the next in Monero if that suits you better, with no penalty either way.
Is my crypto payment linked to my identity?
Not on our side — there's no account to link it to, since none was ever created. The blockchain itself is a separate question: Bitcoin and most token transfers are publicly traceable to the sending wallet, which is exactly why privacy-minded buyers tend to choose Monero specifically.
