If you need a phone number to receive a verification code (OTP) for Google, WhatsApp, Discord, or Telegram, our marketplace lets you rent one instantly using USDT. This article walks you through the exact 7-step purchase flow — from picking a product to receiving your SMS — with realistic timing, network details, and what to do if something goes wrong.

Step 1: Pick Your Product

Browse our catalog and select the service you need. For example, you might see: - Google Voice rental — $1.50 for 24 hours - WhatsApp OTP number — $0.80 per code - Discord verification number — $1.20 per code - Telegram SMS rental — $0.90 per code

Each listing shows the price in USDT, the supported country (e.g., USA, UK, Canada), and the rental duration. Click "Add to Cart" or "Buy Now" to proceed.

Step 2: Enter Your Delivery Email

After adding the product to your cart, you'll see a form asking for your delivery email. This is where we send the SMS code once it arrives. Make sure the email is correct — we don't resend to a different address. You'll also see a note: "We never ask for your password. Only your email."

Step 3: Choose Your Network (TRC20 / ERC20 / BEP20)

Next, select the blockchain network for your USDT payment. We support three options:

NetworkToken TypeTypical FeeConfirmation TimeExplorer
TRC20USDT (Tron)~$0.801-3 minutestronscan.org
ERC20USDT (Ethereum)~$3.505-15 minutesetherscan.io
BEP20USDT (Binance Smart Chain)~$0.201-3 minutesbscscan.com

We recommend TRC20 for most users — it's cheap and fast. If you're using an exchange like Binance or KuCoin, TRC20 is usually the default. Your wallet (e.g., Trust Wallet, MetaMask) must have enough USDT on that network to cover both the product price and the network fee.

Step 4: Get the Payment Address

After selecting your network, the system generates a unique deposit address and shows the exact amount you need to send (product price + any network fee, if applicable). For example, if the product costs $1.50 and the TRC20 fee is $0.80, you'll see: "Send exactly 2.30 USDT to this address."

Copy the address carefully. We recommend using a QR code scanner if available. Double-check that the network matches — sending TRC20 to an ERC20 address will lose your funds.

Step 5: Send the Exact Amount

Open your wallet or exchange app and initiate a USDT transfer. Paste the address, enter the exact amount shown, and select the same network. Confirm the transaction. You'll see a TXID (transaction hash) — save it. You can check its status on the blockchain explorer: - TRC20: tronscan.org - ERC20: etherscan.io - BEP20: bscscan.com

Most transactions confirm within 1-3 minutes for TRC20/BEP20, or 5-15 minutes for ERC20. If it takes longer, don't panic — network congestion can delay confirmations.

Step 6: Wait for Confirmation

Once the blockchain confirms your transaction (usually 1-3 minutes for TRC20), our system detects it automatically. You'll see a status page update: "Payment received — processing your order." This usually takes another 1-2 minutes. The total flow from payment to delivery is typically 5-10 minutes end-to-end.

If 15 minutes pass and you haven't received anything, check the blockchain explorer to confirm the transaction is complete. If it's confirmed but our system hasn't updated, contact support.

Step 7: Receive Your SMS Code

When the SMS arrives, we send it to your delivery email. The email includes: - The phone number used - The OTP code - Any additional instructions (e.g., "This code expires in 5 minutes")

If you rented a number for a specific service (e.g., Google Voice), you'll also get the number itself so you can use it for verification. For one-time OTPs, the code is sent directly. If you don't see the email within 2 minutes of confirmation, check your spam folder.

What to Do If Something Goes Wrong

We've tested this flow hundreds of times — it works. But if you hit an issue: 1. Check the blockchain explorer first. If your transaction is unconfirmed after 30 minutes, it may be stuck due to low gas. You can accelerate it (if your wallet supports it) or wait. 2. If confirmed but no delivery, contact our support on Telegram: @jasonma127. Include your TXID and email address. We typically respond within 5-10 minutes. 3. If you sent the wrong amount or wrong network, we cannot refund automatically. Contact support — we may be able to help depending on the situation.

Why This Process Works

We built this checkout to be as straightforward as possible. No accounts, no KYC, no unnecessary steps. You pay with USDT, we deliver the SMS. The blockchain provides transparency — you can verify the payment yourself on the explorer. Our support is human and responsive.

Frequently asked questions

What is the minimum amount I can pay with USDT?

The minimum order is $0.50 USDT. However, network fees may make very small orders uneconomical. For TRC20, the fee is about $0.80, so a $0.50 product would cost $1.30 total.

How long does it take to get my SMS after payment?

Typically 5-10 minutes total. TRC20 confirms in 1-3 minutes, then our system processes the order in 1-2 minutes. The SMS is sent to your email immediately after that.

What if I send the wrong amount?

Our system only processes payments that match the exact amount. If you send less, it will remain pending. If you send more, the excess is not automatically refunded. Contact @jasonma127 on Telegram for assistance.

Can I get a refund if the SMS doesn't arrive?

If the blockchain confirms your payment but you don't receive the SMS within 30 minutes, contact support. We will investigate and either resend the code or issue a refund. Refunds are not guaranteed for user errors (wrong network, wrong amount).

Do I need to create an account to buy?

No account required. You only provide your email for delivery. No passwords, no personal info beyond that.

Which network should I use?

We recommend TRC20 (Tron) for most users. It's fast (1-3 min confirmation) and has low fees (~$0.80). ERC20 is slower and more expensive. BEP20 is also fast but less commonly supported by exchanges.

How do I check my transaction status?

Use the blockchain explorer for your network: tronscan.org for TRC20, etherscan.io for ERC20, bscscan.com for BEP20. Enter your TXID to see confirmations.

What if I need help after hours?

Our Telegram support @jasonma127 is typically available 24/7. Response time is usually under 10 minutes. If there's a delay, we'll get back to you as soon as possible.
