This specific DataESIM plan is exclusively provisioned for network access within Brunei Darussalam. For travelers navigating the Borneo island, it is crucial to understand that connectivity will cease immediately upon crossing into Malaysian territories, such as Miri or Kota Kinabalu. For example, driving from Miri (Malaysia) to Bandar Seri Begawan (Brunei) will result in a loss of service at the border. For continuous, high-performance data across multiple Borneo nations, we advise opting for our regional Asia Pacific eSIM plans.
