Why Use an eSIM in Vietnam?
Vietnam has a rapidly expanding digital infrastructure, but not all mobile options are foreigner-friendly. Airport kiosks can be overpriced, and local shops often require passport registration.
Using an eSIM can avoid all of that:
✅ No need to visit a store
✅ Set up in minutes using an app or QR code
✅ Great 4G/5G speeds in cities and many rural areas
✅ Switch plans as needed without swapping SIM cards
✅ No passport required
What Is an eSIM?
An eSIM is a virtual version of a traditional SIM card. It’s embedded in your phone and activated digitally. No physical card, no waiting in lines, and no fumbling with tools to open your SIM tray.
