How billing works
Balance-based activations
Your SMSTwins balance acts like prepaid credit. When you request a virtual number, we place a hold for the listed activation price. If the OTP arrives, the hold is captured. If the waiting window expires without SMS, the hold is released automatically.
This model aligns our incentives with yours: you pay for working verification infrastructure, not for silence on the line.
Crypto top-up
Add funds from the Billing page using supported cryptocurrencies and networks. Choose your coin, enter a USD amount, and complete payment on our secure checkout with a dedicated deposit address.
Credits apply after on-chain confirmation. Refer friends to earn commission on their top-ups — see your Referrals dashboard for details.
Pricing varies by route
Activation prices depend on country, service, and real-time supply. Popular routes may cost less; scarce inventory costs more. The activation picker always shows the current price before you confirm.
Developers can call list_prices via the Simple API or browse service pages for SEO-friendly overviews of common combinations.
