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

This particular CheapESIM plan is valid only within Brunei. For travelers exploring Borneo, it's crucial to understand that if you drive from areas like Miri, Malaysia, your internet connection will stop once you cross the border, for instance, at the Sungai Tujoh border post. To ensure uninterrupted connectivity across multiple countries like Brunei and Malaysia (including Sabah and Sarawak), we recommend purchasing a regional eSIM from CheapESIM. Our clear plan definitions help you avoid unexpected charges and ensure your travel budget is spent wisely on seamless, cross-border data.
