This particular EastESIM plan is valid only within Brunei. This is an important distinction for travelers exploring the island of Borneo. If you're planning to drive from Brunei into neighboring Malaysian states like Sarawak (e.g., from Bandar Seri Begawan to Miri) or Sabah, your EastESIM connection will stop once you cross the border. For a truly seamless experience across Borneo, we highly recommend exploring our multi-country Asia plans, which often include both Brunei and Malaysia, keeping you connected throughout your adventure.

Is this EastESIM plan valid for parts of Malaysia (Sabah/Sarawak) as well, or exclusively for Brunei?
