After spending 2 years in Vietnam and returning every now and then, it’s safe to say we’ve tried the different options long enough to know which to recommend and which not.

So in this article, we’ll cover all the essentials you need to know about before buying a SIM card or eSIM package in Vietnam.

Why you should get a Vietnam SIM card

While WiFi is widely available in Vietnam, in your hotel, hostel, or resort, as well as in almost all cafes and restaurants, getting a local Vietnam SIM card is the way to go for a comfortable trip.

The most significant benefit of buying a Vietnam SIM card package is being able to comfortably use ride-hailing apps like Grab (Uber), using Google Maps for navigation, and using Google Translate.

And while it’s true that most locals and businesses in Vietnam use apps like WhatsApp and Zalo for communicating, having a local number has proven useful for us.

Since you’re reading this blog, we assume you’re not in the group that wants to explore Vietnam while being “offline.” (nothing against those people – respect!)

Should you get a physical SIM or eSIM for Vietnam?

In 2023 it’s very common for most to already have phones supporting the eSIM technology.

Buying a Vietnam eSIM is the most hassle-free option, as you simply buy it online, scan the QR code you receive and install it on your phone in a matter of minutes. No need to go to any store or mess around with it at the airport.

So if your phone supports eSIMs, there’s no reason not to get one.

We are big supporters of the eSIM technology and have had it since we got a phone that supported it a few years ago.

Note: Many Vietnam eSIM packages you can find online don’t come with any text or calls, except the Gigago eSIM packages (as of now).

But that’s also the case with some of the standard SIM packages at the airport. Most only give you data.

So if you need calls and texts, just make sure your plan includes it (we will recommend the best packages below).

Where to buy your Vietnam SIM card

The three most common ways to buy your Vietnam SIM card are at the airport, online, or at one of the official mobile carrier stores in Hanoi, Ho Chi Minh City, Da Nang, or any other city.

1. Buy a physical Vietnam SIM card at the airport

The simplest way to buy your physical Vietnam SIM card is upon your arrival at the airport.

All Vietnamese airports are full of kiosks selling Vietnam SIM card packages from operators like Viettel, Vinaphone, Mobifone, and Vietnamobile. (more about the best ones later)

Just walk up to the kiosk, and you will get your Vietnam SIM card installed and ready to go in minutes.

We highly recommend comparing packages of at least two kiosks to find the best deal, as they don’t always offer the same packages or prices.

And while some have better deals for shorter periods, some have better deals for longer trips.

Note: Please note that to buy a physical SIM card, you need a passport, as they will have to register the package in your name, as is the official requirement. This is not required if you buy an eSIM.

2. Buy your Vietnam eSIM online

It’s straightforward to buy a Vietnam eSIM online and activate it in a matter of minutes.

Getting an eSIM online is especially convenient if you’re entering Vietnam by land border from Cambodia or Laos. If you’re on an organized bus trip, you usually don’t have enough time to sort your SIM at the border.

And of course, having a pre-installed eSIM when arriving by plane to Vietnam, means that as soon as you land, you’re online.

We’ve been following the providers of Vietnam eSIMs since they started offering them and compiled a list of the best ones below.

Gigago

• great selection (7, 10, 16, 30 days)
• unlimited data or fixed data packages
• calls & text available (local number)

Airalo

• data only
• great options for 7, 15, and 30 days

TripRoaming

• • data only
  • multiple Asian countries packages

Holafly

• data only
• unlimited data plans for 7, 15, and 30+ days

3. Buy your physical Vietnam SIM online

You can order your Vietnam SIM card online and get it delivered to your home address or pick it up at the airport.

This way, you get a much better deal than buying it directly at the airport.

You simply go to the counter (you get instructions upon booking), and you’re in and out in a few minutes.

Best options for buying a physical Vietnam SIM online:

• 4G SIM Card for pickup at Ho Chi Minh City Airport or
  4G SIM Card for pickup at Ho Chi Minh City Hotel
  • Network: VinaPhone
  • Validity: 10, 15, or 30 days
  • Data options: 2 GB/day, 10 GB total, or unlimited
  • Type: data only or calls included

• 5G SIM Card for pickup at Da Nang Airport

  • Type: data only or calls included

4. Buy your Vietnam SIM card at the official store

You can buy your Vietnam SIM card at one of the official stores of mobile carriers across all cities.

Buying your package at the official carrier store like Viettel or VinaPhone can get you better deals than at airports or smaller reseller shops.

How much does a Vietnam SIM card package cost?

Vietnam SIM Card packages are very affordable and cost upwards of 4 USD for a smaller amount of data and about 10 USD for an excellent data package with text and calls included.

Before getting a package, you must also buy the actual SIM card, which usually costs between 50.000 and 60.000 VND (about 2.5 USD).

Mobile data packages often change names, and what they offer, so we won’t go into specifics about each carrier’s packages. But we will give you a reliable estimated cost of a Vietnam mobile package.

Please note that the prices and packages you will find at Vietnam airports are significantly different and often much higher than what you would pay at the carrier’s store.

Recommended packages by Viettel and VinaPhone

There are many packages to choose from, but Viettel and VinaPhone each have a great monthly package available for years already.

These packages you can buy exclusively at the official stores.

• Viettel offers a 1-month package for 120.000 VND (about 5 USD), with 2 GB of high-speed internet per day and 60 minutes for calling.

• VinaPhone offers a 1-month package for 129.000 VND (about 5 USD), with 2 GB of high-speed internet per day, 1000 minutes in the network, and 50 minutes of calls outside the network.

Do you get calls and texts on your Vietnam SIM card package?

Most Vietnam SIM card packages you can buy at the airport don’t come with any calls or texts, and you would need to go to the mobile carrier shop to get a different package.

The airport options are usually limited, as they’re special packages aimed at tourists and only include data. And they differ from the official ones you can get at the carrier.

You could top-up some money to your account, though, and get calls and texts like that. Calls in Vietnam cost about 1.800 VND per minute, and texting costs about 250 VND per SMS.

But we’re happy to recommend Gigago – Vietnam’s first eSIM provider, as their packages usually include at least some calls and texts.

Which Vietnam mobile carrier is the best? 

There are 4 major mobile carriers in Vietnam, but the two best networks are Viettel and Vinaphone.

Sticking to the first two is best because it will allow you to go anywhere in the country and have a great connection.

1. Viettel

We’ve used Viettel a lot throughout the country and had a great experience, from Ho Chi Minh City to Hanoi and even some more remote places like Ha Giang and Ban Gioc Waterfall.

Viettel has the best coverage of all mobile carriers in Vietnam and has a 40% market share.

2. VinaPhone

VinaPhone has the second-best network coverage with a 30% market share and is a great choice.

While we don’t have as much experience with VinaPhone as we have with Viettel, we know it’s reliable and can highly recommend it.

3. Mobifone

Mobifone, with about 22% market share, is only recommended if you stick to the cities, as its coverage outside the main areas gets bad fast.

So if you’re only visiting, let’s say, Ho Chi Minh City, Da Nang, and Hanoi, you will likely be fine. But not so much in the countryside.

4. Vietnamobile

We recommend avoiding Vietnamobile as we had bad experiences with the coverage and connection, even in cities.

We made the mistake of not buying an eSIM package in advance as usual, and we purchased a Vietnamobile package last minute at the Nha Trang airport – never again.

Don’t trust their cheap packages!

How to top up your Vietnam SIM prepaid package?

Topping up your Vietnam mobile package is simple in almost every convenience store, like Winmart, Circle K, or 7/11.

Often, these stores have dedicated systems where you just provide them with your phone number, and they top up how much you want to your account.

And if they don’t have that system, you will receive a code on your receipt that you must use/call on your phone to top up.

Also, you can buy top-up vouchers or scratch cards and simply use the codes to top up.

TIP: If you’re unsure how to top-up your Vietnam SIM package, simply ask the store workers, and they will be happy to help you, even if they don’t know much English.

One time in Hue, they couldn’t get the system to work in a Winmart, so the worker transferred the amount of money we wanted to top-up from her account to our account (she also had Viettel).

So she saved the day, as three other nearby stores had the same issue.
