Do you want to go to South Korea but are worried about internet access? In such cases, you can freely connect to the internet overseas, including in South Korea, by simply downloading an eSIM to your smartphone. Please try using the convenient eSIM, which you don't have to worry about losing.

In this article, we will explain in an easy-to-understand manner how to choose a South Korea eSIM and its advantages and disadvantages for first-time users. Please read until the end.

What is a South Korea 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. The biggest difference is that the form, size, and the hassle of replacement are completely different.

What Phones are Compatible with eSIM?

Before booking please confirm that your mobile device is compatible with eSIM and the local network. Be aware that an administrative charge will apply if there are phone compatibility issues, even after booking. Steps to Verify: Go to your device's Settings > Cellular/Mobile Data/SIM Card options and look for the option to ‘Add cellular/mobile data plan/eSim’.

When you visit South Korea, it is a big advantage of eSIM to be able to connect to the Internet smoothly from the moment you land at the airport. In the case of traditional SIM cards, you need to purchase at the airport shop or have time to pick up your pre-ordered SIM. However, by downloading the eSIM in advance, you can connect to the network the moment you get off the plane.

This will help you make your trip more efficient, such as arranging a taxi or giving directions to your hotel.

2. No risk of loss or damage

Traditional SIM cards are very small and require careful handling. Especially when replacing it at a travel destination, the risk of loss or damage increases. On the other hand, eSIMs don't have a physical shape, so you don't have to worry about them being lost or damaged. You don't have to worry about opening the SIM tray with a small pin or accidentally dropping the SIM card.

3. Dual SIM possible

1. Limited models

To use an eSIM, you'll need a smartphone or tablet that supports eSIM. Newer models are now compatible with eSIM, but older models and some mid- and low-end devices don't support eSIM.

This will take you through the hassle of checking if an eSIM is available on your current device. If you need to buy a new device to use the eSIM, you'll also need to consider the costs involved.

2. Not available on multiple devices

Traditional SIM cards can be replaced between devices. Therefore, one SIM can be used on multiple devices. However, since the eSIM is built into the device, it is difficult to easily move it between multiple devices. Therefore, it may be inconvenient for those who use multiple devices during their trip to Korea.

3. I can't use my phone number

Your eSIM data plan may not provide you with a unique phone number or may require an additional fee.

This can be inconvenient in situations where you need a local phone number (for example, to make a restaurant reservation or contact a hotel). Conventional SIM cards often provide a phone number as a set with data communication, so this is a point to keep in mind when considering the use of eSIM.
