Which is better for a tourist in Vietnam, an eSIM or a physical SIM at the airport?
I land in Hanoi on Saturday evening. Should I buy a SIM at the airport or install an eSIM before I fly?

If your phone supports eSIM, installing one before you fly is the easiest choice. You get data the moment you land, so you can book a ride and open your arrival card QR code without queuing. Check that your phone is unlocked and supports eSIM.
A physical SIM from a Vietnamese carrier sold at the airport is often cheaper per gigabyte and gives you a local number, which helps with delivery apps and some bookings. The downside is the queue after a long flight, and a passport is needed to register it.
A reasonable plan is to install an eSIM for the first days, or buy a SIM at the airport counter in the arrivals hall, not from a street seller. Compare data allowance, the length of validity and whether tethering is allowed.
Keep Wi-Fi in mind for the first hour. Our Vietnam travel guide has more arrival tips.
