Frequently asked questions

It's a real, temporary phone number you rent to receive an SMS verification code — for signing up to an app or confirming an account — without using your own SIM.

Usually within a few seconds of the service sending the SMS. The code appears in your dashboard automatically; there's nothing to refresh, and the API long-polls so you get it as soon as it lands.

If the number never receives a code within its window, the reservation is refunded to your wallet automatically. You're only charged for a number that actually delivers.

You top up a prepaid wallet with cryptocurrency (Bitcoin, Ethereum, USDT, USDC and more) and spend from your balance per number. No subscription, no card on file, no chargebacks.

Numbers cost different amounts to source in different countries, and some services are pricier to verify. The price for your selected country and service is always shown before you spend anything.

Numbers are temporary and issued per reservation. For a follow-up code on the same number you can extend the session while it's active; otherwise each request gets a fresh number.

While reserved, a number is yours alone and isn't handed to another account for that service. Numbers are meant for one-time verification, not long-term account ownership.

Unused wallet balance from failed reservations is credited back automatically. Top-ups themselves are spent as you use the service; reach us from your dashboard for anything unusual.
