## What is QuackSMS?

QuackSMS is an enterprise-grade virtual SIM infrastructure designed for individuals, security researchers, privacy-conscious professionals, and developers. Unlike public 'free SMS' websites where thousands of strangers share a single number and can read incoming verification codes, QuackSMS allocates a **100% private, virgin line exclusively to you** for your session duration.

### Core Value Propositions

1. **Real Cellular SIM Numbers (Non-VoIP)**: Our lines originate from tier-1 telecom carriers (AT&T, Verizon, Vodafone, EE, Orange, Jio, etc.), bypassing VoIP detection filters on platforms like WhatsApp, Telegram, Tinder, and Google.
2. **100% Automatic Refund Guarantee**: If an SMS code is not delivered within the active timer (15–20 minutes), the order is automatically canceled and 100% of your funds are instantly returned to your balance. Zero human ticket wait times.
3. **190+ Countries Supported**: Access numbers across North America, Europe, Asia, Latin America, Africa, and Oceania.
4. **1,200+ Services Pre-Configured**: Instant dedicated lines for WhatsApp, Telegram, ChatGPT/OpenAI, Google/Gmail, Instagram, Discord, Facebook, Amazon, PayPal, and more.
5. **Developer REST API**: Automated order placement, live webhook relays, real-time WebSocket listeners, and headless automation support.
