Buying a SIM card at Ha Noi Airport (Noi Bai): Travelers Guide

Arriving at Noi Bai International Airport in Hanoi can be an exciting yet stressful experience for travelers. Navigating a new country and language while making sure you have working phone service is key. Getting a local Vietnam SIM card should be at the top of your to-do list when passing through immigration and customs.

This guide will provide everything you need to know about getting SIM card at Noi Bai airport

How to get SIM card at Noi Bai Airport

I. Should I buy a SIM card at Noi Bai Airport (HAN)?

Buying a SIM card at Noi Bai airport when you land is definitely an efficient option over finding and purchasing one in the city later. However, it largely depends on a few factors:

What you plan to use it for

If you only need basic functionality like maps, transportation, translations and internet access, an airport SIM will suffice. But if you’re staying long-term or need lots of data and calling minutes, shop around in Hanoi for better deals.

How long you’re staying

For short Vietnam trips under 2 weeks, an airport SIM card will likely meet your needs if you mostly use apps and internet data. Those staying longer would benefit more from a monthly plan bought in the city.

Data and minutes you’ll need

Airport kiosk SIMs tend to cater more to short-term tourists who won’t use as much data or call time. If you’ll need lots of high-speed data or domestic/international calling, purchase a SIM in Hanoi instead.

So if your travel plans don’t require an immediate SIM connection upon landing, take a ride into Hanoi and shopping around at cell phone stores there instead.

II. Where to Buy a SIM card at Noi Bai Airport?

There are a few options for purchasing SIM cards once arriving at Hanoi’s international airport:

1. Buying online before departure and pickup at airport

Some travelers choose to order ahead of time  before departing for their trip. This allows you to complete the purchase, activation, and registration process in advance so the SIM is ready when you arrive. Two major mobile operators, Viettel and Vinaphone offer this pickup service at Noi Bai Airport.

The two main options are the service counters of Viettel and Vinaphone, both located in area B near the arrivals exit on the ground floor of Terminal 2. Viettel’s counter is in section B8 and Vinaphone’s is in section B9.

While convenient, there are a few potential downsides to consider. You’ll need to research to ensure the SIM you buy will work with your device and has the right plan for your needs. There’s also a risk of delays if anything goes wrong with shipping or activation. Picking up in the airport may also be more expensive than buying locally.

Note: Online pre-purchase is a viable option but be sure to read the fine print to avoid issues after a long flight.

2. Buying at airport upon arrival

Purchasing a SIM card upon arrival at Noi Bai Airport offers the benefit of immediate connectivity in Vietnam without having to prepare beforehand.

There are a few options for buying a SIM at the airport. Viettel, Vinaphone and MobiFone both have service counters near the arrival exit in Terminal 2 where you can pick from data packages and calling plans. An alternative is certain booths in the arrival halls that sell various network SIMs.

While convenient, buying at the airport may be more expensive than purchasing in Hanoi. You also have less time for research and comparison of plans and features. However, for travelers who want connectivity straight away or can’t pre-order online, airport purchase removes stress.
