This CoreESIM data plan is provisioned exclusively for use within Cambodia's geographical boundaries. Should your itinerary include crossing into neighboring territories, such as Thailand (e.g., from Bangkok) or Vietnam (e.g., to Ho Chi Minh City), your data service will cease. For multi-country journeys in Southeast Asia, CoreESIM recommends reviewing our regional eSIM options or acquiring separate country-specific plans to ensure continuous connectivity across borders.
