WiFi & Connectivity
Stay connected at Tan Son Nhat International Airport — free WiFi, eSIM options and local data for Vietnam.
Airport WiFi at SGN
Registration required to connect — look for the sign-in page after joining the network.
Viettel has by far the strongest and fastest network in Vietnam, with Mobifone and Vinaphone as solid alternatives; given how consistently travelers report weak airport wifi here, a local eSIM (or a global reseller on Viettel) is the more dependable option the moment you land.
Free wifi typically needs a passport-number or phone-number login and is widely reported as slow and drop-prone during busy periods — don't rely on it if you need to sort out an e-visa or ride-hail booking right after landing.
