Which crypto reveals the least when you buy an eSIM? (and our Monero answer)

Is any coin UnlistedSIM accepts private?

No. Bitcoin, Litecoin, Ethereum, Tron and Solana are public ledgers: every payment stays readable by anyone, with no login and no time limit. Bitcoin.org says that all Bitcoin transactions are public, traceable and permanently stored, and the same holds for the other chains we accept.

What differs is how much one payment exposes about the rest of your money. That depends on the ledger model of the coin, on how your wallet manages addresses, and above all on where the coins came from. A coin bought on an exchange carries your verified identity in the exchange's records, whatever the chain.

No coin changes what the mobile network sees either: the visited network still sees your device (IMEI) and approximate location. Our checkout is private; it is not network anonymity. See who sees what.

Does UnlistedSIM accept Monero (XMR)?

No. We don't accept Monero (XMR), and the payment page has no XMR option. Never send XMR to an address that claims to be ours: we have no Monero address. If this changes, this page and the changelog will say so.

Many privacy-minded buyers ask for Monero because it is designed to hide more than the coins we accept: Monero's own documentation says that, with its stealth addresses, only the sender and receiver can determine where a payment was sent. As of October 2026, Silent.link, PikaSim, nadanada and Stellar eSim list XMR on their sites, and a forum tester reported that VoidMob accepts it.

What does each coin reveal when you pay for an eSIM?

Each payment shows at least the sending address, the receiving address, the amount and the time. The table adds what else each coin exposes. The coin pages go into detail: Bitcoin, USDT on Tron, USDT on Ethereum, USDC, Ether, Solana and Litecoin.

UTXO or account: why does the ledger model matter?

Because it decides whether one payment can expose the rest of your money.

• UTXO coins (Bitcoin, Litecoin). A wallet holds separate coins and can receive each payment on a new address. Bitcoin.org recommends a new address for every payment you receive. A payment shows only the coins it spends and the change it creates. The leak comes from combining coins: the Bitcoin white paper notes that a multi-input transaction reveals that its inputs had the same owner. Coin control lets you choose which coins pay.
• Account coins (Ethereum, Tron, Solana and their tokens). One address holds everything and keeps one public history: balances, tokens, every transfer, every application used. Ethereum.org adds that each account keeps a nonce, a counter of the transactions it has sent. A separate address for payments helps, but a new address must first receive the fee coin (ETH, TRX or SOL), and that funding transfer links it to the wallet that sent it.

That is why, among the coins we accept, Bitcoin or Litecoin sent from your own wallet, with a fresh address and no coins mixed in from elsewhere, usually exposes the least. It is still a public payment.

Why is the exchange usually the biggest leak?

Because an exchange ties your coins to your verified identity, whatever the blockchain.

Exchanges verify customers 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. When you withdraw coins, the exchange records the destination address, the amount and the time against your account.

If you withdraw straight to our deposit address, the exchange's records show a payment to that address. If you withdraw to a wallet you control and pay from there, the exchange records a withdrawal to your own wallet. The next step stays visible on chain to anyone who follows it, so this limits what the exchange's records say; it does not erase the link.

One practical point: top-ups are matched by their exact amount. If an exchange takes its withdrawal fee from the amount you send, the payment arrives short and cannot be matched automatically.

What does UnlistedSIM see and keep about a crypto payment?

We see what the blockchain shows, plus the link to your account that only our records hold.

• Matching. Each top-up has its own exact amount, and the payment is matched to your account by that amount. You never send us a wallet address.
• What we keep. Once a payment is matched, we keep the coin, the network, the amount and the transaction ID. From the transaction ID, the sending address can be read on the public chain.
• Deposit addresses. They are currently fixed per network and shared by all customers. The blockchain shows that a wallet paid that address, not which account it credited. Treat the address as linkable to UnlistedSIM: we never print it on this site, and it appears only on the payment page of your account.
• No identity. No ID document, no selfie and no card. No email is asked at checkout or needed to log in: a random account number is your login. You may add an email in the client area for receipts, reminders or recovery of the account number; it stays optional.
• Logs and requests. Visitor IP addresses are not written to our web server access logs and are never attached to an account. We answer only legally binding orders under the law of Panama, where the operating company is registered.

The full list is on what we collect, and retention periods are on data retention.

Can a stablecoin issuer freeze the tokens I pay with?

Yes, according to the issuers' own terms.

• Tether (USDT). Tether's terms of service, updated 26 February 2026, say it may freeze Tether tokens held by a user and may blacklist an address that holds Tether tokens (sections 2, 8 and 16).
• Circle (USDC). Circle's USDC terms, updated 12 December 2025, say Circle reserves the right to block certain USDC addresses and to block transfers to and from an address on chain (section 13).

These terms do not mean that a payment will be frozen. They mean that a stablecoin has an issuer that can act on addresses. Bitcoin, Litecoin, ETH and SOL have no issuer with such terms. A stablecoin does not reveal more on chain than other tokens, but its amount reads directly in dollars.

Which habits reduce what a crypto payment reveals?

Ordinary, legitimate habits that keep a payment apart from the rest of your financial life:

1. Pay from a wallet you control, not straight from an exchange account.
2. On Bitcoin or Litecoin, let the wallet use a new address, and use coin control so unrelated coins are not spent together.
3. On Ethereum, Tron or Solana, keep one address for payments only, apart from your savings and income.
4. Use an address you have never published: not one from a social profile, a donation page or an invoice.
5. Keep the transaction ID private. Posted in public, it links your address to the payment.
6. Send the exact amount, on the exact network. A wrong network or a short amount cannot be matched.

These habits limit what strangers can read. They do not hide anything from a court: We answer only legally binding orders under the law of Panama, where the operating company is registered.
