How to Buy an eSIM With USDT (TRC-20): Step by Step, No Card, No Account

Why USDT is the easiest crypto for an eSIM

USDT (Tether) is a stablecoin: one USDT is meant to be worth one US dollar. That makes it the most natural way to pay for something priced in dollars. You do not have to worry about the price moving between opening the invoice and sending the money.

The catch is that USDT exists on several blockchains, and the fees are very different on each. For small payments like an eSIM, TRC-20 (the Tron network) is usually the cheapest and most widely supported option at exchanges. That is the USDT network we accept.

The golden rule: the network you send on must match the network on the invoice. USDT sent on the wrong network cannot be recovered. Always choose TRC-20 / Tron when you pay us in USDT.

If you prefer something other than USDT, we also accept TON, Solana, USDC, ETH, BTC and Monero. See how to buy an eSIM with crypto for the trade-offs.

Step by step: paying with USDT TRC-20

1. Choose your plan on the plans page and press "Buy". Local plans start from $1.20.
2. Select USDT (TRC-20) as the payment method. You will see an invoice with an exact amount and a Tron address (it starts with a T).
3. Copy the address with the copy button. Do not type it by hand. Pasting avoids typos, and copy buttons avoid hidden characters.
4. Send the exact amount from your wallet or exchange, on the TRC-20 / Tron network.
5. Wait a few minutes. USDT on Tron usually confirms in a few minutes. The order page updates by itself, and you do not need to refresh.
6. Install your eSIM. When the payment confirms, the QR code appears, usually within a minute. A PDF with the instructions and your order code downloads automatically.

The exchange-fee trap (and how to avoid it)

This is the most common problem we see. Many exchanges subtract their withdrawal fee from the amount you type. You enter 10 USDT, the exchange takes its fee, and 9-something USDT arrives. The invoice is then underpaid.

To avoid it:

• When you withdraw from an exchange, look for the line that says "amount received" or "you will receive". Make sure that number matches the invoice.
• If the exchange only lets you type the amount *sent*, add the withdrawal fee on top.
• Sending from your own wallet (Trust Wallet, TronLink and so on) is simpler, because the network fee is paid separately in TRX and the full amount arrives.

If you did underpay, the money is not lost. Contact support with your order code and TXID, and we will sort it out by hand.

Minimum amounts

Every coin has a minimum payment set by our payment gateway. For very cheap plans, some coins may not appear at checkout because the amount is below their minimum. In that case:

• choose another coin from the list,
• add a second eSIM to the same order, or
• buy in our Telegram bot with Telegram Stars, which works for any amount.

Where to find your TXID

The TXID (transaction ID, sometimes called "hash") is the receipt of a crypto transfer. You will need it if anything goes wrong.

• In a wallet: open the transaction in your history. There is a long string labelled "Transaction ID", "Hash" or "TXID".
• On an exchange: go to withdrawal history and open the withdrawal. The TXID is usually shown with a link to a block explorer.

The TXID is safe to share with our support. It proves the payment without revealing anything secret. Never share your seed phrase or private key with anyone, including us. We will never ask for it.

What if the invoice expired?

Invoices are valid for a limited time. If you sent the money after the invoice closed, the funds did not disappear. Write to support in our Telegram bot with:

• your order code,
• the coin and network,
• the amount, and
• the TXID.

A person will match the payment manually during support hours (09:00–21:00 Central European Time).

Quick checklist

• Network: TRC-20 / Tron
• Address: copied with the button
• Amount: exact, and the amount *received*, not sent
• After paying: save your order code (it is also in the PDF)
