The most common mistakes when paying with crypto are choosing the wrong network and entering the wrong address. USDT is a stablecoin that moves on several different blockchains, so the network you use really matters. In this guide, we explain step by step how to send USDT TRC20, the differences between sending from an exchange and from a personal wallet, and, in the final section, how to top up your OnaySIM balance. This article isn't investment advice; it only covers the technical steps of a transfer.
What is the TRC-20 network?
TRC-20 is the token standard on the Tron blockchain. USDT on this network usually confirms quickly, and fees are often lower than on the Ethereum network. TRC-20 wallet addresses start with a capital "T" and are 34 characters long, which gives you a quick way to check that an address belongs to the right network.
The same USDT also circulates as ERC-20 on Ethereum and as BEP-20 on BNB Smart Chain. Addresses on those networks usually start with "0x". Even though it looks like the same token, the networks are independent of each other, and assets sent on one network don't automatically move to another.
How to send USDT TRC20 from an exchange
Sending from your crypto exchange account is the most common method. The steps vary slightly from exchange to exchange, but the general flow looks like this:
- Go to the Assets or Wallet section of your exchange account and select USDT.
- Click "Withdraw" or "Send."
- Paste the recipient address and select TRC20 as the network. Some exchanges label this option "Tron" or "TRX."
- Enter the amount, then check the exchange's withdrawal fee and the net amount the recipient will receive.
- Confirm the transaction by completing the security steps, such as an email code, an SMS code or an authenticator app.
Exchanges usually deduct the withdrawal fee as a fixed amount in USDT, so you don't need to hold TRX separately. Some exchanges also set a minimum withdrawal amount, so check that limit before you send.
Sending from a personal wallet: why you need TRX
If you send from a wallet you control, such as TronLink or Trust Wallet, network fees are paid in TRX, the Tron network's native coin. If your wallet doesn't hold enough TRX, the USDT transfer will fail. So:
- Keep some TRX in your wallet alongside your USDT.
- Check the estimated fee your wallet app shows before you send.
- Keep in mind that the fee can vary depending on network conditions and on whether the recipient address has received USDT before.
Common mistakes and safety tips
Choosing ERC20 instead of TRC20
The most critical mistake is selecting ERC-20 or another network when sending to a TRC-20 address. Many exchanges block the transfer up front when the address format doesn't match the network, but a wrong transfer that does go through usually can't be reversed, and your funds may be lost. Before sending, make sure the network you select exactly matches the one the recipient specified.
Copying the address carelessly
Never type an address by hand; copy and paste it. After pasting, compare the first and last few characters with the source. Some malware can swap crypto addresses copied to your clipboard, which is why this check matters.
Sending a large amount all at once
If you're sending to an address for the first time, send a small test amount first. Once the test reaches the recipient, transfer the rest. This small precaution keeps the cost of any mistake to a minimum. Also, because crypto regulations vary from country to country, make sure you follow the rules of the platform you use and the laws where you live.
What is a TxID and where do you find it?
A TxID (transaction ID or transaction hash) is the unique code assigned to every transfer on the blockchain. After sending, you can find it in your exchange's withdrawal history or in your wallet's transaction details. You can look up this code on a block explorer such as Tronscan to track the status of your transfer. In payment notifications, the TxID is used to confirm which transaction is yours. For a closer look, see our guide on what a TxID is and how to find it.
On a block explorer, your transaction will usually show as "success" or "confirmed." If it stays pending, wait a few minutes. With exchange withdrawals, the exchange's own internal checks may hold the transfer for a while before it's broadcast to the network. If a transaction from a personal wallet shows as failed, the most common cause is not having enough TRX.
Checklist before you send USDT TRC20
- Network: Is TRC20 selected as the network?
- Address: Does the address start with "T," and do the first and last characters match the source?
- Amount: Is the net amount the recipient will receive correct after fees?
- Fee: If you're sending from a personal wallet, do you have enough TRX?
- Record: Did you save the TxID after the transaction?
How to top up your OnaySIM balance with USDT TRC-20
OnaySIM balances are topped up with USDT on the TRC-20 network. Here's how it works:
- If you don't have an account yet, sign up for free and log in.
- Go to the top up page and copy the USDT TRC-20 address shown there.
- From your exchange or wallet, send to that address with TRC20 selected as the network.
- Once the transfer is complete, submit your payment notification and include the transaction's TxID.
- After an admin reviews and approves your notification, the balance is credited to your account.
Once your balance is loaded, you can start your SMS verifications by choosing a service and country on the get a number page. If no code arrives for an order, the charge is refunded to your balance. If you run into any issue with your payment, you can reach our support team on Telegram.
Conclusion
The answer to how to send USDT TRC20 is actually simple: choose the right network, check the address carefully and send a small test amount the first time. If you use a personal wallet, keep enough TRX on hand; if you send from an exchange, check the withdrawal fee and the net amount. When topping up your OnaySIM balance, submitting a payment notification with your TxID after the transfer makes it easier to verify your payment.
