Does my EastESIM offer free roaming in Vietnam from my home country SIM?

EastESIM itself doesn't offer 'free roaming' in the traditional sense, as it's a separate data plan for your destination, not an extension of your home carrier. If you're using your regular SIM from the US, UK, or Australia, you'll likely incur significant international roaming charges in Vietnam. EastESIM provides a cost-effective alternative by giving you local rates on data, connecting you to Vietnamese networks like Viettel or Vinaphone directly. It's designed to replace expensive roaming, not to enable it, saving you money while exploring Hanoi or Ho Chi Minh City.
