Yes, it is highly recommended to install and activate your CoreESIM for Nauru before your flight departs or during a layover where reliable Wi-Fi is available (e.g., in Brisbane). Connectivity at Nauru International Airport (INU) upon arrival is typically very limited or non-existent for new connections. Pre-installation ensures immediate data access upon landing, allowing you to use navigation, communication apps, and confirm arrangements without delay.
