eSIM South Korea man with Airalo data pack

As technology advances, travelling abroad has become more accessible and convenient using eSIMs. This is especially true for South Korea, where the best eSIM for visitors is undoubtedly Airalo. 

In this blog post, we’ll explore eSIMs, why they benefit travellers in South Korea, and how to purchase an eSIM South Korea.

What is an eSIM?

An eSIM, or embedded SIM, is a digital SIM card that is embedded within a device. It works like a physical SIM card, allowing users to connect to multiple cellular networks and access data, calls, and SMS services. 

Unlike a physical SIM card, an eSIM does not require swapping out or inserting a new one. Instead, the eSIM is downloaded and activated on your phone or device.

Why is the eSIM card South Korea so convenient?

When travelling to South Korea, visitors often face the issue of purchasing a local SIM card to stay connected to cellular networks. However, this process can be time-consuming, as it requires finding a reliable seller, purchasing the SIM card, registering the SIM in your name, and activating the SIM card. 

With an eSIM for South Korea, you don’t need to do any of the above. 

Instead, visitors can purchase and activate an eSIM on their device without visiting a physical store or navigating the language barrier.

Additionally, Airalo eSIMs for South Korea provide unlimited data for two of the most popular plans, ensuring that travellers have constant access to the internet throughout their trip.

What is the best eSIM in Korea?

Airalo currently offers 2 x Data Packs for South Korea eSIM. These plans provide unlimited data!Ā 

In addition, both plans are very affordable, especially when you consider there is no cap on data usage for them.

These eSIMs for South Korea offer visitors fast and reliable internet access throughout their stay in Korea.

These two plans offer unlimited data, allowing visitors to stay connected without worrying about running out of data.

The 10-day data package is priced at $32 and valid for 10 days from the activation date. 

The 30-day plan is priced at $62 and is valid for 30 days from the activation date. 

From experience, the South Korea eSIM has an excellent connection all over South Korea. Therefore, you will have access to fast and reliable internet throughout your stay in the country.

How to Buy and Download eSIM South Korea

Buying an eSIM in South Korea is a straightforward process. Whether you need a Korea SIM card 30 days validity or one that covers you for a shorter duration, there are a few great options.

Important: Your device must be compatible with eSIM. Please check this list to see if your device supports eSIM before purchasing an eSIM for South Korea.

Then, you can purchase an eSIM online through the Airalo website. 

Download the Airalo app, and purchase a data package. 

You can choose the 10 Days Data Pack OR 30 Days Data Pack for Korea if you need unlimited data.

Follow the steps to activate the eSIM for Korea just before you arrive (remember that the data pack starts from the activation date). 

A Few Tips: 

  • Before arriving in South Korea, switch from your current mobile provider to the South Korea eSIM provider. Don’t stress; there is a step-by-step guide on how to do it during installation.
  • Once your eSIM card is activated, turn off data for all apps you don’t use, including those that can use a lot of data. Apps such as Instagram, YouTube, and Netflix will eat up your data quickly, so wait until you reach your hotel and access the free wifi. 
  • And, if you want the freedom to instantly send those videos home to friends and family of you on a DMZ Tour from Seoul or of you eating and drinking in the alleys of Seoul, the best eSIM for South Korea works like a charm. 

And, if you want to extend your stay in South Korea (which is highly likely, cos it’s a fantastic destination), you can buy another eSIM for South Korea on the Airalo app within minutes.

It’s so easy!

Regional eSIM to Travel in Asia

One of the things I love most about Airalo eSIMs for International Travel is that they offer Regional eSIMs and Global eSIMs too. 

If you plan to do a region of countries at once (say South East Asia, for example), then your best bet is to buy a regional Asialink eSIM.

It means that if you’re travelling through multiple countries in the same region at once, then the one Regional eSIM (which covers 13 countries) is all you need to stay connected as you travel around.
