[For Beginners] eSIM Setup Guide - Complete in 3 Minutes!
In this article, you can learn how to set up an eSIM in about 3 minutes.
In addition, we will introduce what eSIM is and what benefits it offers.
What is an eSIM? | Differences and Advantages from a Physical SIM
An eSIM is a SIM card built into your smartphone, allowing you to use it without having to physically insert or remove a SIM card like with traditional SIM cards. You can keep your physical SIM card and enjoy affordable data communication when traveling abroad.
The contract and activation procedures can be completed online, so you can start using it right away, even just before your trip. With eSIM, there is no need to replace the SIM card, so there is no risk of it being lost or damaged, and you don't have to return it either.
Here are five steps to help you set up your eSIM in just three minutes.
STEP 1 | Purchase an eSIM plan
Visit the eSIM sales store and select a plan based on your destination, data volume, and number of days.

How to run a speed test
You can run a speed test by searching "internet speed test" on Google.

What to do if you can't connect
If you are still unable to connect to the Internet after completing the settings up to STEP 4, there may be a problem with the APN. We will explain the settings below.

Please make sure that the APN information in the email, including the username and password, is blank.

A: Some devices do not support eSIM. Although eSIM is becoming more common, older models often do not support it. It is important to check whether your device is compatible.
