Buy a virtual number for SMS verification
No contract, no monthly plan, no SIM in the mail. Pick what you need, pay from your balance, and keep the money if the code never arrives.
How do I buy a virtual number for SMS verification?
Register on SMS Nitro, top up at least $5 by card or crypto, search the app you want to verify and pick a country. The number is delivered instantly and your balance is charged only when the SMS arrives. For longer use, buy a rental for a day, a week or a month.
How pricing works
- Per code: you pay once per verification received. Prices start at $0.05 and vary by app and country.
- Rentals: a fixed price for 24 hours, 7 days or 30 days with unlimited incoming SMS.
- Wholesale: loyalty tiers lower the per-code price as your monthly volume grows.
- No code, no charge: the frozen amount is released automatically if nothing arrives.
Payment methods
Card (Visa, Mastercard, American Express, Apple Pay, Google Pay) through Stripe, or crypto (USDC and SOL on Solana) with no processing fee. Your balance never expires and can be used for any app or country.
Cheap virtual numbers without the public-inbox risk
The cheapest numbers in the catalog cost a few cents because they come from countries with large virtual number pools. They are still private and reserved for you. The price table on each app page shows the cheapest country and the most reliable one side by side, so you can trade cost for success rate consciously.
Buying in volume
Developers and agencies buy through the REST API or any software that speaks the SMS-Activate protocol. Loyalty levels, cashback on deposits and a dedicated manager are available from $10 of monthly top-ups.
