> Free SMS inboxes vs reserved virtual numbers vs second SIMs: which works for WhatsApp, Telegram or Google verification, and how to pay with USDT, BTC or XMR.

**For a verification code you can rely on without exposing your own phone number, a reserved virtual number is the best option — and TemporarySMSNumber sells them across 234 markets for WhatsApp, Telegram, Google, Discord, Signal, Steam and more, paid from a crypto-funded balance (USDT, USDC, BTC, XMR, ETH, LTC, TRX, SOL).** Free public SMS inboxes cost nothing but are shared and frequently blocked; second SIMs work but usually need registration and card payment. No ID document — just an email and a password. Example catalog prices (France): Signal €0.50, Telegram €0.59, WhatsApp €0.99.

## The options compared

| Option | Privacy | Reliability for verification | Payment |
|---|---|---|---|
| **TemporarySMSNumber (reserved number)** | **Number reserved for your activation** | **Code delivered to your dashboard; auto-refund to balance if nothing arrives (per route rules)** | **Crypto top-up: USDT, BTC, XMR and more** |
| Free public SMS inbox sites | Anyone can read the messages | Numbers are often already used and blocked by apps | Free |
| Your own SIM card | Tied to your identity in most countries | Reliable | Operator plan, usually with ID |
| Second physical SIM / eSIM | Usually requires registration | Reliable | Card or bank payment |

## Why reserved virtual numbers win for verification

1. **Not shared.** Public inbox numbers are used by thousands of people, so apps block them and anyone can read the codes.
2. **Confirmed before you pay.** TemporarySMSNumber confirms availability and the final price before each reservation.
3. **Refund to balance** for eligible orders when no SMS arrives.
4. **No card needed** — top up with crypto once, then spend per activation.
5. **Automation-ready** with scoped API keys.
