Planning a trip to Vietnam then definitely get yourself a local sim card on arrival! There is no better way to stay connected while traveling and save on high roaming costs. This is your guide for buying a sim card in Vietnam with everything you need to know. Where to buy one, up to date prices, why, which provider has the best network and my recommendations.

This article is up dated with the latest info on Vietnam sim cards per September 2021.

Over the last 7 years I visited Vietnam more than 10 times and the first thing I do when arriving is buying a sim card. On my way to visit every country in the world I research sim cards for tourists everywhere I go and wrote already more than 70 guides for buying local sim cards: Hong KongThailand, Indonesia, Italy, USA, etc.

Also have a look at my recommendations for the best sim card for Asia, although I recommend you getting a local sim card in Vietnam.

My recommendation

Let's keep it short and simple there is only one Vietnam sim card that I recommend you buying and that is Viettel! Why?

  • Viettel has the best 4G/5G network in Vietnam
  • A Viettel sim card will cost you on average about $2 - 45,000 VND
  • For $1.30 - 30,000 VND you can already get 7 GB data for 1 week
  • For $5.20 you get 60 GB for 1 month

Enjoy your trip to Vietnam!

Why buying a Vietnam sim card

Asia is much more modern than you may think and there is WiFi EVERYWHERE! So why is it worth it buying a sim card. Well there are multiple reasons, but the most important one is to stay connected while traveling. You don't want to go offline as soon as you leave your hotel. Using a taxi app, finding a nearby restaurant, getting direction on Google Maps all becomes a lot more difficult with a local sim card.

And please don't use international roaming, because a Vietnam sim card is cheap and data bundles are AMAZING VALUE FOR MONEY! This is Asia, some things are dirt cheap and so are local sim cards and data bundles.

Also please don't fall for one of those international sim cards! I researched all of them and most of them I would almost call a SCAM. Some are worth considering, but only for short trips. Have a look at my article with the best international sim cards.

Mobile Internet Providers Vietnam

Let’s first see which providers are available on the market. There are 4 main mobile internet providers in Vietnam: 

  • MobiFone
  • Viettel
  • Vinaphone

On top of that you have a couple small operators that offer sim cards like Vietnamobile, but their network is limited to the big cities only. Not worth it for tourists! More about the 4G and 5G network in Vietnam later.

Also love to recommend a great boutique hotel in Ho Chi Minh City: The Myst Dong Khoi. Totally worth spending a couple bucks extra.

All I can say is get this done as soon as you land. On the airport in Hanoi and Ho Chi Minh City there are endless opportunities for buying a Vietnam sim card and in the city there are mobile phone stores everywhere. Finding a Vietnam data sim is really easy, finding the best one is a challenge!

I recommend you to buy a sim card for Vietnam at the airport in either Hanoi or Ho Chi Minh City. At these shops you can pay buy credit card and there is no need to get cash first. Also these people know exactly what they are doing and they can give you the best advice and it goes fast. Make sure your sim card is working before you walk away.

Finding a prepaid sim card in Ho Chi Minh City is as easy as buying bananas. You will see the 4G signs everywhere! Buying a Vietnam sim card in an official mobile internet provider shop is already a mess, then you can imagine what it is like in any kind of tour agency/information shop.

My advice: don’t even be bothered! Buy your Vietnam sim card at the airport when you arrive. Normally I don't advice travelers to buy a sim card at the airport as those are always more expensive, but saving $2 is not worth the hassle in this case!

Buying a sim card at Saigon Airport Ho Chi Minh City

There are many opportunities for getting your Vietnam sim card upon arrival There is already a kiosk before you even go through customs. After customs there are about 6 different shops all selling the same packages for different prices and as soon as you step outside there are again about 5 different kiosks where you can buy a Vietnam sim card for tourists.

As soon as you walk down the stairs after customs in Ho Chi Minh Airport you will walk up to seemingly endless tourist information shops which are all selling Vietnam sim card packages for tourists. On your left you have the Vinaphone, Viettel and Mobifone shops all next to each other.

Buying a sim card at Hanoi Airport Noi Bai

At the International Arrival Hall 2 all the mobile phone operators have a kiosk. They are located on both sides at the end, it is impossible to miss them. They only close for a couple hours at night, operating hours from 6 am till 2 am. Rule of thumb is that for around $10 you will get 10 GB data on sim cards sold at Hanoi Airport. That said in the city you will get 100% more data for the same price.

Looking at the above network coverage maps in Vietnam, we can clearly see that Viettel has the best network by far. As I have been traveling extensively around Vietnam over the past year I can confirm that in most places off the beaten path there is only a Viettel phone signal available. That said in all the major tourist destinations in Vietnam you will find a signal of all operators.

But trust me for long bus rides you want a Viettel sim card. Also Viettel is the first and so far only mobile internet provider that offers 5G in Vietnam. Their 5G network was launched on December 1st 2020 and is currently only available in Hanoi and Ho Chi Minh City.

My experience buying a Vietnam sim card

Just to prove a point last time I traveled to Vietnam I bought a Mobifone sim card to see if it was really that much of a difference. I mostly stayed around Ho Chi Minh, the Mekong Delta and Quang Binh Province.

May be it was also because I ended up at a friendly guy in one of the many mobile phone shops who was helping me so patiently and without asking me a single time: ‘you buy sim card now?’. For updating this article in September 2021 I roamed around many different phone shops for information and was basically done with all the sales people hassling me... buy now? You want? LOL.

When I explained him I only wanted data and stayed around for about 9 days my guy said: try this Mobifone sim package.

VND 100,000 = $4.2

  • 12GB data - 4G speed
  • Unlimited data - 3G speed
  • No calling, no texting
  • Valid 30 days

I decided to put Mobifone to the test as it has the weakest network in Vietnam. So was I satisfied with it? More or less.

The internet speed was alright. I never really had problems watching Instagram stories or streaming videos on Facebook. When I entered buildings though the signal got pretty weak and in my hotel room (I stayed at Grand Hotel Saigon) I had just 1 bar 4G sometimes. Let’s say it could have been better!

In the rural areas of Quang Binh there was often no signal and sometimes I had 3G. But for the most of my trip to Vietnam the Mobifone sim card worked lets say ok. Next time though I will buy a Viettel prepaid sim card again! Especially as I want to try their 5G network in Vietnam.

I wrote many guides for buying tourist sim cards and I know what to expect and what to look for. Vietnam is a different piece of cake, prepare yourself for an intense journey if you travel to Vietnam. Haggling is part of the culture and when you go to a market or even a shop never buy something for the original price unless it is printed on it, but even then! ;)

Vietnam is always a good idea, I love the country, but also be prepared to fight for your right or get ripped off! But, whatever you do, do it with respect.

I thought I had seen it all after writing guides for buying a sim card in Thailand or tourist sim cards in Indonesia. Unlike most places around the world prices for sim cards in Asia are not fixed. Thailand just has too many packages available, Indonesia simply is a mess, but what to say about Vietnam? Oh god!

Welcome to the jungle! Finding the best sim card in Vietnam almost felt like mission impossible! Good thing: data sim cards in Vietnam are very cheap as you have read above.
