It depends on the specific EastESIM plan you choose. Many of our popular plans are indeed designed for multi-country travel across Asia, perfect for adventurers exploring several destinations. For example, our 'Southeast Asia Explorer' plan covers countries like Thailand, Vietnam, Malaysia, and Singapore under a single package. Always check the plan details on eastesim.com to confirm the included countries. If you're hopping from Ho Chi Minh City to Phnom Penh, a regional plan ensures seamless connectivity without needing a new eSIM for each border crossing.
