Is this CheapESIM plan valid for other Southeast Asian countries like Thailand?

This particular CheapESIM plan is specifically designed for use within Vietnam only. If your backpacking adventure includes crossing borders into neighboring countries such as Cambodia, Laos, or Thailand, your internet connection will not extend to those regions. For travelers exploring multiple destinations on the 'Banana Pancake Trail,' we highly recommend our regional Southeast Asia eSIM plans. These multi-country options offer continuous coverage across several nations, providing better value and convenience than purchasing individual eSIMs for each country.
