Vietnam-only or Asia regional?

Choose a Vietnam-listed prepaid plan with enough data for Hanoi, Ho Chi Minh City, Da Nang, Hoi An, and long bus or train routes. Install the QR on Wi-Fi before arrival and keep offline maps for rural transfers.
For maps, Grab, messaging, hotel bookings, and light social use, 8-12 GB works for many two-week Vietnam trips. Add more if you use hotspot, upload videos, or work remotely.
Most Vietnam country plans work well in major tourist cities and coastal areas through local mobile networks. Boat trips, mountain roads, and rural transfers can still have weaker signal.
For Vietnam only, choose a Vietnam eSIM. If your itinerary also includes Thailand, Singapore, Malaysia, South Korea, or Japan, compare the Asia regional country list before buying.
