When developing, testing, or signing up for platforms like OpenAI (ChatGPT), WhatsApp Business, Google, or Telegram, you have likely encountered these errors:

1. How VoIP Detection Works
When you enter a phone number, the system checks real-time carrier records via Carrier Lookup APIs. If the number is identified as virtual VoIP (e.g., Google Voice, TextNow), the platform immediately blocks it.
2. The Solution: Authentic Physical US Carrier SIMs
To guarantee instant OTP delivery and eliminate carrier rejection errors, you must use real physical SIM lines (AT&T, Verizon, T-Mobile).
