Microsoft phone verification: ERC20 vs TRC20 — Which is Cheaper?

Why Microsoft phone verification needs USDT

Many users hit a wall when Microsoft asks for a phone number to verify their account. If you lack a credit card or want to avoid KYC sharing, USDT payment for a temporary SMS number is the ideal workaround. At SMS-PRO (sms-pro.com), you can buy a virtual number and receive the Microsoft verification code in seconds. But which USDT network is cheaper for this transaction?

ERC20 vs TRC20: Cost comparison for SMS numbers

As of January 2026, a single temporary SMS number for Microsoft verification costs 0.45 USDT on SMS-PRO. The difference lies in network fees:

• **ERC20 (Ethereum):** Transfer fee is ~1.5–2.5 USDT (varies with ETH gas). So buying one number via ERC20 costs 0.45 + ~2.0 = **2.45 USDT** total.
• **TRC20 (Tron):** Transfer fee is fixed at 0.00 USDT (no fee). So buying one number via TRC20 costs exactly **0.45 USDT**.

For bulk purchases (e.g., 10 numbers = 4.5 USDT), ERC20 fees multiply: 4.5 + 2.0 = 6.5 USDT vs TRC20 = 4.5 USDT. TRC20 is clearly cheaper.

How to buy a Microsoft verification number with TRC20 USDT

1. Go to [SMS-PRO](https://sms-pro.com) and select "Microsoft" as the service.
2. Choose a country (e.g., USA, UK) – prices vary slightly, but the USDT cost is fixed at 0.45.
3. At checkout, select **TRC20** as your USDT network.
4. Send the exact amount (0.45 USDT) to the provided Tron wallet address.
5. Within 30 seconds, the number appears in your dashboard. Enter it on Microsoft’s verification page and wait for the SMS to arrive.

Why TRC20 is the smart choice for privacy-focused users

• **No bank or card needed**: You only need USDT in your wallet (e.g., Trust Wallet, MetaMask).
• **No KYC**: SMS-PRO does not require identity verification.
• **Fast and cheap**: TRC20 transfers confirm in seconds with zero fee.
• **Supports multiple services**: Besides Microsoft, you can verify Telegram, WhatsApp, Binance, and more.

FAQ

Q: Can I use ERC20 if my wallet only supports it? A: Yes, but you will pay a higher network fee (~2 USDT) per transaction. It's better to convert to TRC20 if possible.

Q: How long does the SMS take to arrive? A: Typically within 30 seconds, but up to 2 minutes in rare cases. The number is active for 20 minutes.

Q: What if I don't receive the code? A: SMS-PRO offers a refund or replacement if the SMS fails within 5 minutes.

Q: Can I reuse the same number for multiple verifications? A: No, each number is single-use. You can buy a new one for each verification.

Q: Is it safe to use USDT for this? A: Yes, USDT is a stablecoin pegged to USD, so the price is predictable. SMS-PRO uses HTTPS and does not store personal data.
