Esim 4G: How to Register and Use

Switching SIM cards is often a concern for many people when traveling internationally due to the hassle and inconvenience. However, thanks to the continuous advancement of technology, Vietnamese travelers no longer need to spend much time and effort switching SIM cards to match the country they are visiting. With just a few simple steps, you can connect to the local mobile network—all thanks to Esim technology.

In this article, let's explore with Vietjet the benefits of Esim and how to activate Esim to prepare for a perfect trip!

Besides plane tickets and visas, Esim 4G is something you should prepare for your overseas trip.

1. What is Esim 4G?

1.1 What is Esim?

"Esim" stands for "embedded SIM," meaning it's embedded in the device. Unlike traditional physical SIM cards, Esim is integrated directly into the mobile device, eliminating the need for users to purchase and install it separately.

Despite its compact size, Esim ensures all the functionalities of a regular physical SIM, such as making calls and using 3G, 4G, and 5G mobile networks.

1.2 Types of Esim

Standard Esim: This type of Esim is used to connect to mobile networks. It performs functions like calling, texting, and internet access. With a standard Esim, you can choose and activate network services from supported carriers and perform communication operations directly on the mobile device.
Data Esim: Data Esim is specifically designed to provide mobile data access services, primarily for internet connectivity. With a data Esim, you can activate mobile data services from supported carriers and access the internet without needing a physical SIM. Currently, the most popular mobile data service packages are 4G, so many people often refer to it as Esim 4G.

2. Benefits of Using Esim 4G

2.1 More Convenience

Esim or Esim 4G eliminates the need to purchase, install, and remove physical SIM cards, providing a smoother and more convenient user experience. Additionally, you can manage multiple eSIMs on a single device, easily switching between carriers and plans without replacing a physical SIM.

2.2 Seamless Network Connectivity

Another advantage of Esim 4G is its ability to provide seamless network connectivity. When using traditional SIM cards, losing connection in areas with weak signals is common. However, Esim 4G will automatically switch to the network with the strongest signal or better availability, ensuring seamless connectivity.

This benefit is especially ideal for those who travel frequently and switch between different networks when abroad. Instead of manually selecting a network, Esim 4G allows you to stay connected automatically.

2.3 Simplifies International Travel

A special benefit Esim 4G offers for international travelers is that it reduces the hassle of buying local SIM cards. Many Esim services now allow you to connect to networks in many countries around the world. This means travelers don't need to search for mobile stores to purchase local SIM cards. With international eSIM 4G, travelers can easily connect to local networks in the country they are visiting. This convenience saves time and effort and can reduce travel costs since you don't need to buy local SIM cards or incur roaming fees.

Esim technology reduces the burden of switching SIM cards during your international travels.

3. How to Register for Esim 4G

To start using Esim, you need to activate it by following these steps:

Check Your Device: First, ensure that your mobile device supports Esim 4G. A list of devices that support Esim 4G can be found on the carrier's website.
Prepare Information: Prepare your ID card and the phone number you are currently using.
You can contact the carrier through the following channels:

To start using Esim, activate it through the website, app, or carrier stores.
