Day-to-day life in Guinea-Bissau runs on WhatsApp, Facebook and TikTok, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +245 number keeps that account tied to the country without using your personal SIM.

OpenAI can ask for the phone again for API access, billing or security reviews.
Guinea-Bissau is a small Portuguese-speaking country on the West African coast, best known for cashew exports and the Bijagós islands. Business and family life run mainly through WhatsApp and calls rather than email. A +245 number helps traders, travellers and the diaspora in Portugal stay easy to reach.
