Should I buy an eSIM before arriving in Nha Trang or get a local SIM card on arrival?

TL;DR
For a short trip, a prepaid travel eSIM is the easiest option because you can connect as soon as you land. For longer stays, a local Viettel, Vinaphone, or MobiFone SIM/eSIM registered with your passport is usually better value, typically around 150,000–300,000 VND for 15–30 days.

If your phone supports eSIM, install a travel plan before flying and activate it after landing at Cam Ranh Airport. Choose a plan using Viettel or Vinaphone coverage in Nha Trang; 5–20 GB is usually enough for a 7–15-day trip.

For a month or longer, compare local plans at official Viettel, Vinaphone, or MobiFone shops in central Nha Trang. Bring your passport for SIM registration; data packages commonly cost about 150,000–300,000 VND for 15–30 days.

Avoid unbranded SIM cards from random airport sellers if you need proper registration and easy top-ups. SIMs at Cam Ranh Airport are often more expensive, so use an eSIM for day one and buy a local card later from an official operator in Nha Trang.
