The coverage of your EastESIM plan depends on whether you've selected a single-country or a multi-country regional plan. For instance, if you purchase an eSIM specifically for Vietnam, your data connectivity will be limited to within Vietnam's borders. However, if your travel plans include neighboring countries like Laos or Cambodia, choosing one of our comprehensive Asia regional plans will ensure seamless connectivity across all included nations. It's important to select the plan that matches your itinerary to avoid losing connection as you cross borders, for example, from Singapore into Malaysia.
