Vietnam SIM Card

One of the options to get internet in Vietnam is the Vietnam SIM card. These cards work just like the cards you use every day on your mobile phone.

SIM cards are available in various sizes, miniSIM, microSIM and nanoSIM. So you have to check which size suits the mobile phone you use.

Having a SIM card before you arrive in Vietnam can save you from having to look for places to buy one and you will be able to enjoy calls and data from the first moment you set foot on Asian soil.

  • Sim 2 Fly: offered by the company Ais. It is one of the best-selling cards with national coverage.
  • Asia 12 Days: this prepaid card is from the Chinese company Unicom and has APN settings.
  • Travel Sim: this True Move H prepaid card is available in several SIM card sizes

Another option is to buy a SIM card in Vietnam. If you choose to do it this way, you can buy it in several places such as airports or company sales points.

When to sign up for an eSIM in Vietnam?

Another option to have internet while traveling in Vietnam is the eSIM card. This type of virtual card works thanks to a chip in the mobile phone that allows you to dispense with the physical card.

One of the great benefits of this type of card is that you can have the contracted rate at the time of purchase, so you will never be without an internet connection.

If you opt for this modern type of card, we recommend using Holafly's eSIM for internet connection in Vietnam. Holafly's internet tariffs allow for 3G and 4G speeds, making them ideal for backpackers or digital nomads who want to work from Vietnam.

Options for connecting to the internet in Vietnam over wifi

The last of the options for internet in Vietnam is probably one of the best known, wifi. If connecting to the internet in Vietnam is a must, you can use one of these two alternatives:

  • Portable Wifi: this is a private connection that avoids cyber-attacks and can connect several devices at the same time.
  • Public Wifi: open networks that you can find in different parts of the country.

Use portable wifi in Vietnam

The portable wifi works thanks to a mini router that you can carry anywhere thanks to its small size. This option allows you to connect several devices at the same time in a secure way.

Portable wifi is purchased on a rental basis, so you must return it at the end of the contract. You should also be careful if it is lost or stolen, as the companies apply a surcharge. If you don't want to have this problem, you can sign up for the Vietnam SIM card or the Hoalfly eSIM.

Some of the options you have to enjoy the internet in Vietnam with portable wifi include:

  • WifiVox: this option is one of the cheapest and allows you to connect up to five devices at the same time, so you can share the connection with your travel companions.
  • Travelers Wifi: this company's router also allows you to connect several devices at the same time and, in addition, if you exceed the daily data contracted, you will not be left without internet, but the speed will be reduced.

Public Wifi in Vietnam

Public wifi is one of the first options we think of when looking on the internet while traveling. Vietnam is no slouch when it comes to public networks.

You can find free internet points in different parts of the country such as stations and airports. Little by little these points are being extended to encourage tourism.

Normally, in order to access these public networks you have to register at the tourist offices located at the airports.

You should be aware that these types of networks make the device vulnerable to cyber-attacks. We recommend that you avoid these networks to avoid unwanted surprises during your trip to Vietnam.

Hotels are another place where you can find free wifi, check with the hotel where you are staying to see if they have this service available.

How does roaming in Vietnam work?

Vietnam is not a country with free roaming so you should pay special attention to this point so that you don't run into unwanted cost overruns when the tariff arrives.

The companies have basic rates if you use the usual rate in a country that is not included in their free roaming zones. So during your trip in Vietnam, if you decide to use the standard tariff, the costs will be as follows:

Roaming rate Vietnam
Companie Price Data Call Rate
O2 £7,2/MB £2/min
Vodafone £6/Day £6/day
Three Mobile £5/Day 3p/min

As you can see this is not cheap, so we recommend using a Vietnam SIM card or an eSIM card, as these are the options that allow you to have data on your mobile in the cheapest way.

Vietnam internet coverage

The Asian continent has one of the best internet connections and Vietnam is not far behind. 5G speed is well advanced on the Asian continent thanks to the development of standalone 5G networks.

Vietnam is positioning itself as one of the most relevant countries when it comes to teleworking. Many digital nomads go to Asian countries to work.

For this reason, the Vietnamese government sees progress in internet speed as essential, and both large and small phone providers are constantly improving the telecommunications infrastructure.

Advantages of internet access in Vietnam

Having an internet connection on your devices when traveling in Vietnam is one of the almost essential requirements when we are organizing the trip.

Being connected at all times to consult any questions that arise during the day is essential, so having a connection on your mobile is very useful to continue having these advantages.

The advantages of having internet in Vietnam are many. Some of them are:

  • Keeping in touch with family and friends to let them know how our stay in the country is going.
