For adventurers exploring Brunei beyond the city, data is indeed critical. While Bandar Seri Begawan is walkable, venturing to destinations like the Ulu Temburong National Park requires pre-booked transport, often coordinated via messaging apps. Offline maps are a good start, but real-time updates for remote forest trails or checking river conditions for longboat trips on the Temburong River mean reliable connectivity from your eSIMAdventures plan is your best companion.
