This specific SouthESIM plan is designed exclusively for use within Vietnam. If your travel plans include exploring neighboring countries like Cambodia, Laos, or Thailand, your connection will unfortunately cease once you cross the border. For seamless connectivity across your entire Southeast Asian itinerary, we highly recommend our regional multi-country eSIM bundles, which offer continuous data across several destinations.
