- Keep your email and number consistent between ChatGPT and the API platform.
Why use a Cambodia number for ChatGPT (OpenAI)?
Day-to-day life in Cambodia runs on Telegram, Facebook and Messenger, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +855 number keeps that account tied to the country without using your personal SIM.
Telegram-based business: Telegram is Cambodia’s main work messenger, so companies and freelancers dealing with Phnom Penh often need a local number to be taken seriously.
OpenAI can ask for the phone again for API access, billing or security reviews.
