A single-country EastESIM plan, like one specifically for Vietnam, is valid only within that country's borders. If you're embarking on an overland adventure from Ho Chi Minh City to Phnom Penh, or from Hanoi into Laos, your Vietnam-specific connection will cease at the border. For seamless travel across nations like Vietnam, Cambodia, and Laos, we highly recommend one of our multi-country Asia plans. These packages are designed for regional exploration, ensuring you remain connected as you cross borders without needing to buy a new eSIM for each country.
