This depends entirely on the specific EastESIM plan you've chosen. A plan designated 'Vietnam Only' will provide excellent coverage with local carriers like Viettel or Mobifone within Vietnam's borders, but connectivity will cease if you cross into Cambodia or Laos. For travelers exploring multiple countries in Southeast Asia, we recommend our dedicated regional plans, such as the 'Southeast Asia Explorer' package. These are specifically designed to offer seamless connectivity across borders, perfect for journeys from Ho Chi Minh City to Phnom Penh or Luang Prabang.
