South Korea SIM Cards: Everything You Need To Know

Are you visiting South Korea soon? Make sure to know what to expect when it comes to purchasing a South Korean SIM card.

Fortunately, Asia is one of the best places where you can buy a SIM card easily. You should be able to find a cheap SIM card pretty much anywhere in Asia. In fact, most data packages are affordable, which makes the whole thing easier!

In this guide, we’ll explain where to buy a SIM card in South Korea in person and online. We’ll also discuss prepaid SIM cards and eSIMs if your mobile supports them.

Before you read this guide, you may wonder if you actually need a SIM card in South Korea. If you don’t mind not having Internet, you’ll likely find free Wifi in restaurants, shopping malls, and hotels.

That said, if you need data to get around, call a cab, or translate Korean – you may want to get a SIM card for your travels in South Korea.

Best SIM Cards In South Korea

If you’re traveling in South Korea, we recommend using a SIM card from LG U+, SK, KT, or Airalo. (I’ll get back to Airalo later on, so keep reading to learn more!)

That said, if you’re planning on visiting other countries during your trip to Asia, you might want to make sure to pick an option that offers coverage in other Asian countries.

How To Buy A SIM Card In South Korea

You can either buy a South Korean prepaid SIM card in person in some international airports, mobile provider stores, convenience stores, or online.

Usually, you can expect higher costs and low data offers at the airport, so we don’t recommend buying a SIM card at the airport. That said, you won’t necessarily find SIM card shops in every airport, so it’s essential to keep this in mind. And, when you see a shop, you might also have limited options.

For this reason, I’d recommend buying a SIM card directly from the mobile provider store. Note that you may need your passport to buy one.

Although, this means you won’t get data right upon your arrival. So, if you prefer to be connected at all times, you could use an eSIM or purchase an Asia prepaid SIM card online.

Now, let’s take a look at the data plans offered by LG U+, SK, and KT.

If you want to buy an eSIM for South Korea, you could purchase one on Airalo. This website offers many eSIM cards worldwide and special plans for Asia and South Korea. I’ve been using Airalo for several months, and it works fine.

  • 10 GB, valid for 30 days for $37
  • 50 GB, valid for 90 days for $100
  • 100 GB, valid for 180 days for $185

The options mentioned above are part of Asialink and offer coverage in 14 countries, including South Korea.

Alternatively, if you’re traveling in other countries that are not mentioned on the list, you can try Discover Global, which offers coverage in 87 countries, including South Korea.

Now, one important thing to note about Airalo is that you’ll need to keep an eye out for the provider in each country. Suppose you ever have trouble connecting to the Internet during your trip. In that case, it might be because you’re connecting automatically to networks and need to select a network manually instead.

When you purchase the eSIM, you’ll get access to the list of networks supported in each country.
