The Terminal 2 international arrivals hall has SIM booths from all three Vietnamese carriers — Viettel (which runs two dedicated booths, one each side after customs, and has the best nationwide coverage), Mobifone and Vinaphone — operating around the clock, though individual kiosks may close 2–6am. Staff activate tourist packs on the spot, but airport pricing is widely reported at two to three times what the same SIM costs at a city store.

Getting online at Ho Chi Minh City (SGN)
Ho Chi Minh City’s airport sits close to the centre; arrivals reach District 1 quickly by taxi or ride-hail, both far easier with live maps.
Most large airports, including Ho Chi Minh City (SGN), offer free terminal Wi-Fi — but that signal ends the moment you step outside to the taxi rank or train, which is exactly when you need maps, ride-hailing and messaging most. Buying a SIM at the counter means queueing after a long flight, showing your passport for registration, choosing from a short menu of tourist bundles, and swapping out your physical SIM so your home number goes offline. None of that is terrible — but all of it is avoidable.
How to be online before you leave the jet bridge
- Before you fly: pick a Vietnam eSIM above and buy it — you'll get a QR code by email in minutes.
- Install it on home Wi-Fi: scan the QR in your phone's cellular settings. Leave the line switched off for now; your home SIM stays your default.
- When you land at Ho Chi Minh City (SGN): turn off airplane mode, enable the travel eSIM's data line, and turn on data roaming for that line. It connects to a local network automatically.
- Walk out connected: maps, ride-hailing and messaging all work before you reach the taxi rank — no kiosk, no queue, no passport photocopy.
