Day-to-day life in Brunei runs on WhatsApp, Instagram and TikTok, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +673 number keeps that account tied to the country without using your personal SIM.
Students and returning Bruneians: Bruneians studying in the UK, Australia or Malaysia keep a local number so family and home services can still reach them.
OpenAI can ask for the phone again for API access, billing or security reviews.
Brunei is small, but its energy sector draws a steady flow of foreign engineers and contractors. With WhatsApp used for almost every personal and business conversation, a +673 number helps outsiders fit into local routines.
