How Can We Help You Today?
Everything you need to know about buying numbers, receiving SMS codes, automated refunds, and 24/7 technical support.
Getting Started
Q.How does NexNum virtual number activation work?
Select your desired platform (e.g., WhatsApp, Telegram, Google, ChatGPT) and country, then click 'Get Number'. You receive an active SIM line immediately. Enter the number on the target app, and your SMS OTP will appear on your dashboard in under 3 seconds.
Q.How long does a virtual number stay active?
Standard SMS activations remain active for 20 minutes. If you need a second verification code or resend, you can click 'Resend SMS' within the active window at zero extra cost.
Q.Are the phone numbers real and private?
Yes. All numbers originate from genuine cellular SIM infrastructure. Numbers are privately allocated to you exclusively during your activation window and are never shared concurrently with other users.
OTP Delivery & Refunds
Q.What happens if I do not receive an SMS verification code?
NexNum operates on a strict 100% Zero-Risk Policy: If no SMS code arrives within the 20-minute window, or if you cancel the number after the 30-second hold, the reserved balance is immediately and automatically refunded to your wallet.
Q.Can I cancel a number and get an instant refund?
Yes. As long as no SMS code has been received, you can click the 'Cancel' button on your dashboard. Once cancelled, your funds are returned to your account balance instantly.
Q.Why did a service say 'No numbers available'?
If high demand temporarily exhausts the active SIM pool for an obscure service, our automated scoring engine protects your balance by declining the request without charging you. New SIM inventory is rotated in real-time every few minutes.
Payments & Wallet
Q.What payment methods are accepted?
We support instant Indian UPI (Google Pay, PhonePe, Paytm, BHIM), Credit/Debit Cards, Net Banking, and Cryptocurrencies (USDT TRC20, Bitcoin, Ethereum, Binance Pay, TRX).
Q.Are there any monthly subscription fees?
No! NexNum uses a pure Pay-As-You-Go model. You only pay for successful OTP activations. Your account balance never expires.
API & Developers
Q.Do you provide an API for automated OTP verification?
Yes! NexNum provides a high-performance telecom API compatible with standard carrier wire protocols. You can integrate getNumber, getStatus, and Webhook callbacks in Python, Node.js, PHP, or Go.
Q.Where can I find the API documentation and keys?
Visit the API Documentation hub at /api-docs to view code samples, endpoint references, and manage your secret API keys.
