Are these real SIM numbers or VoIP?

Both pools exist and we label them. Physical (real SIM) numbers pass verification where VoIP gets rejected; virtual numbers cost less.

What happens if the SMS code never arrives?

The charge refunds itself. Every new number has a 20-minute delivery window with a visible countdown; at zero with no code, the money returns to your balance automatically.

Crypto (USDT, BTC, TON) with no KYC, or bank card. Top-ups start at $5.

Can I keep the number for more than one code?

Yes. Rentals run up to 30 days with unlimited codes in the period, and you can renew the same number.

Do you have an API for automation?

Yes. REST v1 with API keys, plus an SMS-Activate-compatible endpoint (handler_api.php) so existing bots migrate by changing the host. Webhooks push codes to your endpoint.

Can I get a refund to my card or wallet?

Refunds return to your SMS-GO balance and are reusable instantly. Balance is prepaid and non-withdrawable.
