Why use a Serbia number for ChatGPT (OpenAI)?
Day-to-day life in Serbia runs on Viber, WhatsApp and Instagram, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +381 number keeps that account tied to the country without using your personal SIM.
Serbian diaspora: Large Serbian communities in Germany, Austria and Switzerland rely on Viber to reach relatives, and a +381 number keeps them part of those chats.
OpenAI can ask for the phone again for API access, billing or security reviews.
