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

This specific eSIMAdventures plan is designed solely for your exploration within Brunei. This is a crucial detail for Borneo adventurers. If you're driving from neighboring Miri (Malaysia), your connection will unfortunately cease at the Sungai Tujoh border post. For a truly uninterrupted Borneo adventure across both Brunei and Malaysian Borneo (Sabah and Sarawak), we highly recommend opting for our dedicated Southeast Asia Regional eSIM. This ensures continuous connectivity as you traverse diverse landscapes and borders.
