To guarantee 100% instant SMS verification code delivery, you MUST switch on a VPN set to the EXACT SAME country as your virtual number (e.g. use a USA VPN server when registering a USA number). Ensure your VPN is active before pressing "Send Code" in your target app (WhatsApp, Telegram, Google, etc.).

1. What do the Number Delivery Rates (%) mean?
The success rate (e.g. 96.5%) is calculated dynamically across our automated cellular routing network based on thousands of real-time SMS arrival records across recent activations for that service and carrier. Higher delivery rates indicate that SMS verification codes arrive rapidly (within 5–15 seconds) with high reliability.
2. How do Network Carriers & Operators work?
NastySMS connects directly to multiple tier-1 cellular networks (e.g. T-Mobile, AT&T, Vodafone, MTN, Airtel) and dedicated virtual SIM routing pools (e.g. Virtual 1–16).
• Any Carrier (Auto / Recommended): Automatically routes your request to whichever carrier currently has the highest active SIM card inventory and fastest delivery response for your chosen country.
• Specific Carriers (e.g. T-Mobile, AT&T): Allows you to select dedicated mobile network lines if your target service (like WhatsApp or Telegram) requires a specific carrier prefix.
3. What is the difference between Virtual and Physical SIM Carriers?
Virtual lines (e.g. Virtual 12) provide cloud-hosted temporary routing numbers optimized for high-volume SMS verification at affordable pricing.
Physical SIM carriers (e.g. T-Mobile, AT&T, Vodafone) represent direct GSM subscriber lines that bypass strict VoIP filters on security-heavy platforms.
4. Why MUST I use a VPN for virtual numbers?
Platforms like WhatsApp, Telegram, Google, and Tinder cross-reference your device’s IP address with the SIM country. If you attempt to register a USA number from a Nigerian IP without a VPN, the target app will delay or block the SMS. Always activate a VPN set to the number’s country before requesting the code.
5. What happens if no SMS arrives? (Auto-Refund Guarantee)
You only pay for SMS codes that are successfully delivered. If an SMS is not received within 15 minutes, the automated system automatically cancels the order, and NastySMS immediately refunds 100% of your money (₦) back to your wallet balance with zero deductions. You can also click "Cancel & Refund" at any time before receiving the code.
6. How do I top up my NastySMS wallet with Naira?
Click "Top Up", transfer your desired amount to our PalmPay business account (EHIME NATHANIEL OSADOLO), and click the WhatsApp confirmation button to send your receipt. Your wallet is verified and credited within 1–2 minutes!
