Day-to-day life in Costa Rica runs on WhatsApp, Facebook and Instagram, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +506 number keeps that account tied to the country without using your personal SIM.
Eco-tourism bookings: Lodges in Monteverde, La Fortuna and the Osa Peninsula confirm reservations and shuttles over WhatsApp.
OpenAI can ask for the phone again for API access, billing or security reviews.
Costa Rica attracts a steady stream of surfers, eco-tourists and North American retirees, and nearly all of them end up arranging things on WhatsApp. Sinpe Móvil, the national instant-payment service, runs on a Costa Rican phone number, which makes a +506 line useful for paying local businesses. The country’s digital nomad visa has added remote workers to the mix.
