best esim for vietnam : top providers and plans in 2025

Traveling to Vietnam has become easier with digital connectivity, and the use of an eSIM is now one of the most convenient options for tourists. With an eSIM, you can avoid the hassle of buying a physical SIM card on arrival. You simply download the plan, activate it, and get connected within minutes. Whether you need reliable data coverage for Google Maps, ride-hailing apps, or staying in touch with family, the best eSIM for Vietnam ensures you remain online from the moment you land.

Another key advantage is the ability to keep your primary number active on your phone while using a secondary eSIM for data.
