Mobile data in Vietnam is inexpensive by international standards, and getting connected is straightforward whether you'd rather sort it out before you land or handle it at the airport.
eSIM: the easiest option for compatible phones
If your phone supports eSIM, a Vietnam-specific or regional Asia eSIM can be purchased and installed before you even leave home, activating once you land — useful for booking a Grab ride straight out of arrivals without needing to find a SIM counter first. Several providers offer these through simple apps, with data-only or data-plus-calls options.
Physical SIM cards
Local carrier counters at Tan Son Nhat Airport sell tourist SIM cards in arrivals, generally with straightforward data packages aimed specifically at visitors, and staff who can help set it up on the spot. Convenience stores and dedicated phone shops around the city also sell and activate SIMs, usually at lower prices than the airport if you're comfortable waiting until you're in the city.
Wi-Fi as a backup
Most hotels, cafes and restaurants offer free Wi-Fi, generally reliable enough as a backup, though a local data plan makes navigating, booking rides and staying in touch considerably easier when you're out and about.
