What is an eSIM?

An "eSIM" stands for Embedded SIM. Unlike traditional physical SIM cards, it refers to an electronic SIM that is built into the device. In Japan, eSIM-compatible devices were introduced in 2018, and since then the number of users has been rapidly increasing.

Since the eSIM is built into the device, you don't have to worry about it bending or breaking like a physical card. Traditional SIM cards need to be inserted into mobile devices such as cell phones and smartphones, requiring you to remove the back cover of the cell phone and insert it into a specific slot.

Which is Convenient in Vietnam? eSIM, SIM Card, Wi-Fi Router Comparison

When traveling to Vietnam, you have three main options for staying connected: eSIM, traditional SIM card, or a portable Wi-Fi router. Each has its own advantages and disadvantages.

An eSIM is a digital SIM that allows you to access a cellular network without a physical SIM card. It's convenient because you can download it before you travel and switch between your home and local network easily. However, not all devices support eSIMs, and not all carriers in Vietnam offer eSIM plans.

Buying a local SIM card when you arrive in Vietnam is a popular option. It's relatively cheap and gives you access to local call rates and data packages. However, it requires an unlocked phone and you'll need to change your number while using the local SIM.

A portable Wi-Fi router can be rented or bought and provides internet access for multiple devices. This is a good option if you're traveling in a group or need to connect multiple devices. However, it's usually more expensive than a SIM card and you'll need to carry the device around with you.

Below, we have summarized the 3 characteristics and precautions in a table.

3 pros of using eSIM Vietnam

1. Convenient for changes and procedures

By using an eSIM, you no longer need to exchange physical SIM cards. The procedure at the store is simplified when switching to a new plan or trying a different carrier.

2. High convenience for travelers

When traveling to Vietnam, you can use a local prepaid plan even for a short stay. You can save the trouble of buying a physical SIM card, and you don't need to switch back to another plan after returning home. It's perfect as a temporary means of communication for short-term travelers and residents visiting Vietnam.

3. Easy to manage communication charges

Prepaid plans for travelers to Vietnam allow you to charge credit in advance and use it, so you don't have to worry about overuse. It's easy to manage calls and data communication within your budget, and you can avoid unexpected high bills.

1. Limitations on compatible carriers

eSIM is not yet widely adopted, and not all communication carriers support eSIM. Therefore, the carriers you can use may be limited.

2. Device restrictions

To use an eSIM, you need a compatible device. Be careful as older models and some devices may not support eSIM.
