All about Vietnam eSIM, pros and cons, cost, service providers, best prepaid eSIM data plans in Vietnam for tourists, step-by-step guide on how to install, etc.

Vietnam has it all as a holiday destination, from beautiful landscapes, unique culture, great signature food, friendly locals, and sunny weather to free Internet connection almost everywhere. 

Choosing Vietnam as a destination, while most people want high-speed data for their phone during a trip in the country, they have traditionally bought a physical SIM card. Nonetheless, today, many newer phones are equipped with an embedded electronic SIM (aka eSIM) that allows you to connect to Vietnam mobile carriers without having to install a traditional SIM Card. In reality, these new eSIM data plans give tourists lots of convenience but there are a number of drawbacks as well. 

This is why in this post, we are going to cover everything you should know about eSIM (data plans) in Vietnam – including what is an eSIM (in Vietnam), how it works, international operators, local eSIM, features, rates, requirements, and tips on finding the best eSIM for Vietnam travel.

Do I even need mobile data in Vietnam?

Honestly, YES. Vietnam is one of the countries with the most accessible free WiFi system in the world. You can find Wi-Fi in hotels, coffee shops, food and beverage stores, restaurants, and some public places in Vietnam. However, if you are in places without Wi-Fi or with weak signals of Wi-Fi like parks, tourists attractions, or on the roads, then you cannot remain your connection. Even worse, free Wi-Fi also implies many security risks. 

That is a reason why you need mobile data on your phone upon traveling to Vietnam. 

Is eSIM available in Vietnam?

YES, the major mobile network operators Viettel, Mobilefone and Vinaphone currently offer eSIM service for compatible devices. You can download eSIM only to a esim- supported smartphone device.

Apple, Samsung, Oppo, Google, Huawei and Motorola support eSIM functionality within Vietnam for now.

eSIM works everywhere in Vietnam.

What is an eSIM in Vietnam? Types and Features

In short terms, an eSIM in Vietnam is no different from every eSIM in the world. It is an embedded/digital version of the physical SIM card and is physically embedded in the motherboard of your device. 

When you want to change mobile network provider, there will be no physical changing of SIM cards because there are no physical SIM cards involved with an eSIM.

Using an eSIM, you can stay connected by downloading an eSIM profile directly to your handset.

Once you buy a profile for an eSIM for Vietnam, you will obtain a QR code within seconds. You just need to download the QR code, scan it, and join the mobile network. Easy!

👉 Good to know: 

  • eSIM is called virtual SIM or eUICC (Embedded Universal Circuit Card). 
  • An eSIM can hold up many profiles, but you should maintain a maximum of 3 eSIM profiles within an eSIM for the best use. 
  • Because the chip is physically connected inside the handset’s motherboard, we cannot do anything with the eSIM chip, but the eSIM profile. In most eSIM-related documents, people often mention an eSIM in the meaning of an eSIM profile. So here we apply the same to help you follow easily.
