This specific Truly Roaming eSIM plan is valid solely within Brunei. For digital nomads exploring Borneo, it's vital to know that if you cross the border from Miri (Malaysia) into Brunei, your connection will activate, but it will cease upon re-entering Malaysian territory, for example, at the Sungai Tujoh border post. To maintain uninterrupted connectivity across both Brunei and Malaysian Borneo (Sabah/Sarawak), we recommend our regional Asia eSIM plans for comprehensive coverage.
