Each EastESIM plan is designed for specific regions or countries. If you've purchased a single-country plan, for example, for Vietnam, it will only work within Vietnam. Should your journey take you across borders to places like Cambodia or Laos, your connection will cease. For travelers exploring multiple gems in Southeast Asia, we highly recommend our dedicated multi-country Asia plans. These comprehensive plans offer seamless connectivity across various nations, from the vibrant markets of Bangkok to the ancient temples of Angkor Wat, ensuring you stay connected without interruption.
