Vietnam eSIM and Airport Transfer Tips: Get Online and Into Town Without Overpaying

Updated November 2026

The two most stressful moments of most trips are the first hour after landing and the first time your phone has no signal. Here's how to handle both in Vietnam.

Mobile data: eSIM or local SIM?

Vietnam's main networks are Viettel, VinaPhone and MobiFone. Coverage in cities and along main tourist routes is good; remote mountain passes have gaps.

Travel eSIM

• How it works: buy online before you fly, scan a QR code, and switch it on when you land.
• Pros: working data the moment you land, no shop visit, and you keep your home SIM active for bank SMS codes.
• Cons: usually data-only (no local phone number), and your phone must support eSIM and be carrier-unlocked.

Local physical SIM

• Where: carrier counters at the airport, or official carrier stores in town.
• Registration: SIMs must be registered with your passport, and the shop will do this for you.
• Pros: you get a local number, which helps with deliveries, homestay owners and some apps.
• Cons: airport counters can be busy, and you have to swap out your home SIM unless you have a dual-SIM phone.

Airport transfers

General rules for every airport

• Use ride-hailing apps (Grab is the most common) or official taxi queues. Ignore drivers who approach you inside the terminal.
• Make sure the meter is on in a taxi, or agree the fare in the app before you get in.
• If you arrive late at night with luggage or children, a pre-booked private transfer with a name sign takes the stress out of it.

Hanoi (Noi Bai)

The airport is north of the city, and the drive to the Old Quarter usually takes 45 minutes to an hour depending on traffic. Public bus 86 runs between the airport and central Hanoi and is a good budget option in daytime.

Da Nang

The airport is right in the city, only a short ride from most Da Nang hotels. For Hoi An, see our Hoi An guide.

Ho Chi Minh City (Tan Son Nhat)

The airport is inside the city. District 1 is close, but rush-hour traffic can make the trip slow. Public bus 109 connects the airport with the city center.

Money tips for arrival

• Withdraw a modest amount of Vietnamese dong from an airport ATM. Rates at town ATMs and exchange shops are often similar or better.
• Cards are widely accepted in cities, but street food, markets and rural homestays are cash-only.
• Count carefully: 10,000 and 100,000 dong notes look alike, and so do 20,000 and 500,000.

Visas: avoid the fake sites

Vietnam issues e-visas through an official government portal. Many lookalike sites charge extra service fees. Check the official address through your government's travel advice page or the nearest Vietnamese embassy before you pay, and check whether your nationality qualifies for visa-free entry.
