Quick answer
Paying for an eSIM with Bitcoin reveals the paying addresses, the amount, your change and the time to anyone who reads the Bitcoin blockchain, but not your name unless one of those addresses is already linked to you. UnlistedSIM, a no-ID eSIM seller paid in crypto, accepts Bitcoin (BTC) 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 Bitcoin blockchain show about a Bitcoin payment?
It shows the transaction to anyone, with no login and no time limit.
Every Bitcoin transaction is public and permanent. It shows the addresses that funded it (the inputs), the addresses that received coins (the outputs, including the change that goes back to your wallet), each amount in BTC and the time of the block. Bitcoin.org says it plainly: anyone can see the balance and all transactions of any address.
No name is written on the blockchain. The link to you comes from outside it: an exchange that knows your withdrawal address, an address you posted in public, or an earlier payment to someone who knows you. When a transaction combines several inputs, observers usually assume they have the same owner. The Bitcoin white paper itself says this linking cannot be avoided with multi-input transactions.
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 Bitcoin from an exchange reveal my identity?
To the exchange, yes: the exchange is usually the biggest leak, not the blockchain.
If you send BTC straight from an exchange to the deposit address, the exchange records the withdrawal against your verified account: the destination, the amount and the time. Withdrawing to a wallet you control first adds one step. The exchange can still follow that step on the public chain, but its own records then show a withdrawal to your wallet, not a payment to an eSIM seller.
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 Bitcoin address link my payments?
Yes. Every payment from the same address is visible in one list, to anyone who looks.
Bitcoin uses separate coins (UTXOs), not one account, so a wallet can receive every payment on a new address. Bitcoin.org recommends a new address each time you receive a payment, and most modern wallets do this by default. Your wallet also sends the change to a fresh address of yours. That change output stays linked to this payment on the blockchain: if you later spend it together with other coins, those coins become linked too. Coin control, offered by several desktop and hardware wallets, lets you choose exactly which coins pay.
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 Bitcoin?
Send only on Bitcoin, and pick that same network both on the payment page and in your wallet or exchange.
When is Bitcoin a good choice for an eSIM payment?
Good for: Paying from a hardware or desktop wallet that uses a new address for each payment and lets you choose which coins to spend.
Watch out: Network fees rise when blocks are full, and the BTC price can move between sending and crediting. Send the exact BTC amount shown on the payment page, with a normal fee, so the top-up can be matched.
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 Bitcoin 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 Bitcoin?
The same five steps apply to every coin. For Bitcoin, pick Bitcoin 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 Bitcoin: FAQ
Can I buy an eSIM with Bitcoin without ID?
Yes. UnlistedSIM asks for no ID document, no selfie, no ID number and no email. You top up a prepaid balance with Bitcoin (BTC) 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 Bitcoin anonymous?
No. The Bitcoin 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 Bitcoin top-up need?
The Bitcoin network must confirm the transaction 2 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 Bitcoin network fee?
You do. The fee is paid in BTC 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 BTC 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 Bitcoin 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 Bitcoin on the wrong network?
It cannot be matched to your top-up, and it may be lost. Send BTC on Bitcoin 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.
Other ways to pay, coin by coin
Each page explains what one coin reveals, its network and its fee. The pay privately guide compares them all and gives our Monero answer.
