This specific EastESIM plan is designed to provide optimal coverage exclusively within Thailand. While it will keep you seamlessly connected from Chiang Mai to Phuket, if your travel plans include a short trip across the border to Penang, Malaysia, your Thailand-only plan will not extend coverage there. For travelers who enjoy exploring multiple countries in Southeast Asia, EastESIM offers convenient regional plans that cover several destinations under one package. This ensures continuous connectivity as you move between vibrant locales like Thailand and Malaysia without needing a new eSIM for each country.
