Is this eSIM On Trip plan for Brunei also valid for parts of Malaysia like Sabah or Sarawak?

This specific eSIM On Trip plan is designed to provide coverage exclusively within Brunei. This is a vital point for those exploring Borneo. If your journey takes you across the border into Malaysia, specifically to regions like Sabah or Sarawak, your data connection from this eSIM will stop. For example, if you're driving from Miri, Malaysia, your service will end at the Sungai Tujoh border post. To ensure continuous connectivity across both countries, consider a regional Asia eSIM plan that covers both Brunei and Malaysia.
