Frequently asked questions
How much does a temporary number cost?
Prices start at $0.15 per code and depend on the country and app. You see the exact price before renting, and if no SMS arrives during the rental window you're refunded automatically.
How do I pay?
Top up your USD wallet by card (Stripe, with 3-D Secure) or with USDT/USDC on Tron, Polygon, BNB Chain, Base or Solana. Wallet credit is applied automatically at checkout.
Do developer plans auto-renew?
No. Plans are prepaid terms bought from your wallet; when a term ends you return to pay-as-you-go Spark pricing until you buy again.
Are there coupons?
Yes — enter a coupon at checkout for plans, numbers or top-ups. Discounts are shown before you confirm.
