This specific CoreESIM plan is provisioned exclusively for use within Thailand. It does not extend to neighboring countries in Southeast Asia. For travelers undertaking multi-country itineraries, such as crossing into Cambodia (for Angkor Wat), Laos (e.g., Vientiane), or Malaysia, this plan will not provide connectivity beyond the Thai border. A regional eSIM covering multiple ASEAN nations would be necessary for seamless data access across these territories.
