How to Add Balance on SMSOTPS: Deposit Walkthrough
By SMSOTPS Support Team
Adding balance on SMSOTPS is a crypto deposit, nothing else. No card form, no bank transfer form on the deposit page. You sign in, open Add Balance, choose an amount, get an invoice with a payment address, and send crypto from your own wallet to that address.
That is the whole flow, in one paragraph. The rest of this guide is the part people get wrong: matching the coin and the network on the invoice, copying the address instead of retyping it, and knowing where to look after you send.
The outcome first
Balance in your SMSOTPS account, ready to order a number. This is the SMSOTPS add balance flow, start to finish. The deposit page is where that balance comes from. Add Balance does not open a separate balance page — it redirects to the Deposit page. If you are looking for a different Add Balance screen, you already passed it.

SMSOTPS deposit, step by step
- Sign in to your SMSOTPS account.
- Open Add Balance. You land on the Deposit page.
- Pick a preset amount, or enter a custom amount. The live deposit page shows the current amounts and options — use what it shows on the day, not a number from this article, because amounts on the page change.
- Proceed to the crypto payment. A crypto payment gateway generates an invoice with a payment address.
- Send the payment from your own wallet to that invoice address.
- Wait for the transaction to be confirmed on the network. The deposit page says balances are credited automatically after the transaction is confirmed on the network. Check the invoice payment status, then check Deposit History.
This crypto deposit walkthrough is deliberately short on numbers. Minimums, preset amounts, fees, and refund terms are not quoted here as facts. Read them on the live deposit page and in the deposit terms before you send, because those are the numbers that apply to your deposit.
Which coin and network? Read the invoice, not your memory
The deposit page lists USDT (TRC20, BEP20, ERC20), BTC, LTC, ETH, TRX, TON, and SOL among supported coins. That list was checked on 4 Nov 2026. Check the live page again at implementation, because a supported-coin list changes.
Coin and network are two different choices, and both must match the invoice. USDT alone is not enough information. USDT on TRC20, USDT on BEP20, and USDT on ERC20 are three different routes to three different addresses. Sending on the wrong network is the classic way deposits get lost, and it happens to people who were sure they picked the right coin.
Copy the address. Do not retype it. One wrong character sends crypto to an address you do not control, and a crypto transfer does not have a card-payment undo button. After pasting, compare the address on the invoice with the address in your wallet before you confirm. That one comparison is the cheapest insurance in the whole flow.
What to check after you send
Do not close the invoice and hope. Check the invoice payment status first. Then open Deposit History and find your deposit there.
Deposit History lists each deposit with transaction ID, gateway, amount, credited amount, currency, status, and date. Read that row like a receipt. Transaction ID is your proof of payment. Gateway shows which route the deposit took. Amount is what the invoice asked for. Credited amount is what landed in your balance. Currency and date pin down which deposit you are looking at. Status shows where the deposit stands.
Keep the wallet transaction ID. It is the proof of payment and what support asks for. Save it somewhere you can find it again, not just in a wallet app you might switch away from. If a confirmed payment does not appear in your balance, contact support through the help page, and give them that transaction ID plus the Deposit History row. A support message without a transaction ID is a description of a problem. A support message with one is a deposit they can look up.
Before you send: read the terms, because this part is final
The deposit page states that balance top-ups are final and non-refundable, and it links the deposit terms. Read those terms before sending, not after a deposit goes wrong. That sentence is attributed to the deposit page, and it is the reason this article does not quote refund terms as its own facts — the live terms are the source, and they are the version that applies.
The same rule applies to every other number in this flow. If a number matters to your deposit, read it on the live deposit page or in the terms on the day you send. An article that quotes last month's number is worse than an article that tells you where to read today's number.
Transfer Balance is a different section, with a different risk
The deposit page also has a Transfer Balance section. It asks for a recipient account email and an amount, shows a fee on the form, and requires a checkbox confirming the recipient email is correct.
That checkbox is the whole section, in one tick. Read the fee shown on the form before you confirm — this article does not quote a fee amount, because the form on the day is the source. Then check the recipient email character by character. A transfer goes to the account with that email. The checkbox exists because a transfer to the wrong email is a transfer to the wrong account, and there is no point in ticking a confirmation you have not actually checked.
The mistakes that lose deposits
Sending on the wrong network. USDT on the wrong chain, BTC to a USDT address, any coin to an address from a different invoice. Match coin and network to the invoice in front of you, every time, even if you have done this deposit before.
Retyping the address. Copy it, paste it, compare it. Retyping turns a 34-character address into a guessing game, and guessing games with crypto addresses end badly.
Sending before reading the terms. The deposit page states top-ups are final and non-refundable. Reading that after sending is not reading it at all.
Closing the invoice without checking Deposit History. If the deposit does not appear, the row in Deposit History — or its absence — is the first thing support will ask about, along with your wallet transaction ID.
So, what should you actually do?
Sign in, open Add Balance, read the live deposit page for today's amounts and terms, pick your coin and network from the invoice, copy the address, compare it after pasting, send from your own wallet, keep the wallet transaction ID, and check Deposit History after network confirmation. If a confirmed payment does not appear, contact support through the help page with that transaction ID in hand. That sequence — read the live page, match the invoice, copy the address, keep the proof, check the history — is the whole walkthrough, and it is the difference between a deposit that lands and a deposit you spend a week explaining.

Common questions
How do I add balance to my SMSOTPS account?
Sign in, open Add Balance from your account, pick a preset amount or enter a custom one, and proceed to the crypto payment. The gateway generates an invoice; send the crypto payment from your own wallet to the invoice address. The deposit page says the balance is credited automatically after the network confirms the transaction - check the invoice payment status and Deposit History, and contact support if the credit does not appear.
Which cryptocurrencies can I deposit with?
The deposit page lists USDT across several networks, plus BTC, LTC, ETH, TRX, TON and SOL among the supported coins. The live deposit page always shows the current list, so check it before sending.
Where can I check whether my deposit arrived?
Your current balance shows on the deposit page under Account Overview, and the Deposit History page lists each deposit with its transaction ID, gateway, amount, credited amount, currency, status and date. Wait for the network confirmation before expecting the credit.
Can I get a refund on a deposit?
The deposit page states that balance top-ups are final and non-refundable, and links to the deposit terms. Read the terms before you send - a crypto transfer cannot be pulled back once it is on the network.
