Quick answer
Paying for an eSIM with Ether (ETH) reveals your Ethereum address, the ETH amount, the fee and the time to anyone who reads the Ethereum blockchain, along with everything else that address holds and has done. UnlistedSIM, a no-ID eSIM seller paid in crypto, accepts Ethereum (ETH) with no ID and no email at checkout, a top-up from $10 and eSIMs from $1.09. We see the amount and the transaction ID, never an ID document.

What does the Ethereum blockchain show about a Ether (ETH) payment?
It shows the transaction to anyone, with no login and no time limit.
A plain ETH transfer shows the sending address, the receiving address, the amount of ETH, the gas fee and the time. Ethereum.org explains that every account keeps a nonce, a counter of the transactions it has sent, so even the number of payments an address has made is public.
The account model means one address carries everything: its ETH balance, its tokens, its past transfers and the applications it has used. A public ENS name, if you set one, labels the address for everyone.
The blockchain never shows your UnlistedSIM account number, your eSIM or your destination. Those exist only in our records, which are described field by field on what we collect.
Does paying with Ether (ETH) from an exchange reveal my identity?
To the exchange, yes: the exchange is usually the biggest leak, not the blockchain.
An exchange withdrawal of ETH is recorded against your verified account: destination, amount and time. If the destination is our deposit address, that address is in the exchange's records. Paying from a wallet you control means the exchange's records show a withdrawal to you, although the next transfer remains visible on chain.
Exchanges verify their customers' identity under anti-money-laundering rules. Guidance from the Financial Action Task Force (FATF) also asks exchanges and other virtual-asset service providers to collect originator and beneficiary information for transfers, the so-called travel rule. A payment sent from an exchange account is therefore tied to a verified name in at least one database, whatever the coin.
Does reusing a Ether (ETH) address link my payments?
Yes. Every payment from the same address is visible in one list, to anyone who looks.
An Ethereum address does not change between payments, so all of them sit in one public history. You can keep a separate address only for payments, but funding it with ETH is itself a visible transfer from another address. On our side, ETH, USDT and USDC sent on Ethereum arrive at one Ethereum deposit address.
Our deposit addresses are fixed per network and shared by all customers. Anyone who knows that address can see every payment it receives, but not which account each payment credited. Treat it as an address that can be linked to UnlistedSIM: we never print it on this site, and it appears only on the payment page of your account.
Which network should I use to send Ether (ETH)?
Send only on Ethereum, and pick that same network both on the payment page and in your wallet or exchange.
When is Ether (ETH) a good choice for an eSIM payment?
Good for: Paying from an Ethereum wallet without converting to a stablecoin first.
Watch out: The ETH price moves, so the payment page locks the amount for a limited time. Gas comes on top of the amount shown, and the amount that arrives must match the amount shown exactly.
Whatever the coin, the top-up goes to a prepaid balance. The eSIM is bought from it, and the QR code and activation code appear in your account as soon as the eSIM is ready. Unused balance stays on your account and never expires, and it pays for new eSIMs and top-ups, but it is not refundable.
How can I pay with Ether (ETH) more privately?
Use ordinary, legitimate habits that keep a payment separate from the rest of your financial life:
- Pay from a wallet you control, not straight from an exchange account.
- Use an address you have never published: not one from a social media profile, a donation page or an invoice.
- Keep payment addresses apart from savings and income. On coins that use accounts, one address shows everything it has ever done.
- Keep the transaction ID private. Posted in public, it links your address to this payment.
- Remember what no coin changes: the mobile network still sees your device (IMEI) and approximate location. Private checkout is not network anonymity; see who sees what.
UnlistedSIM does not accept Monero (XMR). The pay privately guide compares what each accepted coin reveals.
How do I top up with Ether (ETH)?
The same five steps apply to every coin. For Ether (ETH), pick Ethereum on the payment page.
Top up $10 or more
Choose the amount and the coin (BTC, USDT, USDC, ETH, SOL, LTC). The crypto amount and its rate are locked for 30 minutes.
Send it to the address shown, on the exact network
The payment page shows our deposit address for the coin and network you picked: BTC on Bitcoin, USDT on Tron (TRC-20) or Ethereum (ERC-20), USDC on Ethereum (ERC-20), ETH on Ethereum, SOL on Solana, LTC on Litecoin. Send only that coin on that network: funds sent on another network or in another coin can’t be recovered. The network fee comes on top of the amount.
Send the exact amount shown, then click “I’ve sent the payment”
Each top-up has its own exact amount (down to the last decimals): that is how we find your payment and link it to your account.
Credited once your payment is checked on the blockchain
Your balance is credited once we have checked the transaction on the blockchain, after the network has confirmed it. Typical network confirmation times:
Crypto Network Confirmations Usual time BTC Bitcoin 2 ≈ 20 min USDT Tron (TRC-20) 20 ≈ 1 min USDT Ethereum (ERC-20) 12 ≈ 5 min USDC Ethereum (ERC-20) 12 ≈ 5 min ETH Ethereum 12 ≈ 5 min SOL Solana 1 ≈ 1 min LTC Litecoin 6 ≈ 15 min One balance for every product
If you started from a plan, the eSIM is bought as soon as the top-up is credited, and its QR code appears in your account. What is left stays on your balance for top-ups and other destinations. Unused balance stays on your account and never expires, and it pays for new eSIMs and top-ups, but it is not refundable.
Closed the tab? The pending top-up stays under Billing in your account: open it to see the address and the exact amount again.
Paying for an eSIM with Ether (ETH): FAQ
Can I buy an eSIM with Ether (ETH) without ID?
Yes. UnlistedSIM asks for no ID document, no selfie, no ID number and no email. You top up a prepaid balance with Ethereum (ETH) from $10, then buy the eSIM from that balance. A random account number is your login. Some countries have local SIM registration rules; the Travel eSIM ID Registry lists them with sources.
Is paying with Ether (ETH) anonymous?
No. The Ethereum blockchain is public: it shows the sending address, the amount and the time to anyone. Your name is not on it, but an exchange that knows your address, or a past payment, can link it to you. We ask for no ID and no email at checkout, yet we keep the coin, the network, the amount and the transaction ID once a top-up is matched.
How many confirmations does a Ether (ETH) top-up need?
The Ethereum network must confirm the transaction 12 times before your balance is credited. The table in the payment steps above shows the usual time per network. If you started from a plan, the eSIM is bought from the balance as soon as the top-up is credited, and its QR code appears in your account when it is ready.
Who pays the Ether (ETH) network fee?
You do. The fee is paid in ETH by the sending wallet, on top of the amount shown on the payment page, and it is not taken from your UnlistedSIM balance. Keep enough ETH in the wallet. If an exchange takes its withdrawal fee from the amount, the payment arrives short and cannot be matched by its exact amount.
Can other customers see that I paid?
They can see that a payment reached our address, not that it came from you. Our Ethereum deposit address is shared by all customers, so anyone who knows it can look up every payment it receives. Nobody can tell from the chain which account a payment credited, or who sent it, without already knowing your address. Only our records link a transaction to an account. We answer only legally binding orders under the law of Panama, where the operating company is registered.
What happens if I send Ether (ETH) on the wrong network?
It cannot be matched to your top-up, and it may be lost. Send ETH on Ethereum only, and pick the same network on the payment page and in your wallet. If you made a mistake, contact support from your account before sending anything else. Email replies within 12 hours, 7 days a week, including help with installing and activating your eSIM.
