This specific CoreESIM data plan is provisioned exclusively for use within the geographic borders of the Philippines. It is not designed for multi-country travel. If your itinerary includes transit or extended stays in other Southeast Asian destinations such as Thailand, Vietnam, or Malaysia, you will require a distinct regional or country-specific eSIM. CoreESIM offers various regional plans tailored for seamless connectivity across multiple nations, ensuring continuous service without interruption as you cross borders.
