Why use a Grenada number for ChatGPT (OpenAI)?
Day-to-day life in Grenada runs on WhatsApp, Facebook and Messenger, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +1 number keeps that account tied to the country without using your personal SIM.
Sailing and hurricane season: Yachts often base themselves in Grenada during hurricane season, and crews use a 473 number to coordinate boatyards and marinas.
OpenAI can ask for the phone again for API access, billing or security reviews.
