Data-only eSIM Vietnam is a game-changer for modern travelers, digital nomads, and expats who want reliable, high-speed mobile data—without the need for a physical SIM card or local address. In 2025, as more phones and tablets become eSIM-compatible, data-only plans have become the most convenient, flexible, and cost-effective solution for visitors who want to stay connected across Vietnam. In this in-depth guide, you’ll discover what a data-only eSIM is, who should use it, how to choose the right plan, and how to set up your eSIM for a seamless Vietnam trip.
