Best eSIM for South Korea (2025)


eSIMs are virtual SIM cards embedded directly into your device, eliminating the need for physical SIM cards and offering convenience and flexibility to travelers exploring South Korea. They allow you to stay connected at all times. Plus, you can easily switch between local carriers to get a better signal, all without fiddling with physical SIM cards.

However, the growing number of eSIM providers makes it challenging to choose the right one. I've conducted tests to help you pick the perfect eSIM card for your upcoming adventure in South Korea. Read on to find the best eSIMs for South Korea.

Top 5 eSIMs for traveling in South Korea

What to consider when choosing eSIM for South Korea?

When choosing an eSIM for South Korea, consider your needs carefully. Here are a few pointers to help you pick the right eSIM:

  • Destination coverage: Ensure your preferred eSIM has coverage across South Korea, including big cities and rural areas. If you’re traveling across the region, pick an eSIM that doesn’t only have coverage in South Korea but also in neighboring countries like Japan, China, and more.
  • Communication needs: Decide if you only want data or want to make calls and send messages. Some eSIM providers offer data-only plans, while others include a phone number for making calls and sending SMS.
  • Data requirements: Estimate how much data you’ll need during your South Korea trip and select an appropriate eSIM plan. Some eSIMs offer fixed plans, while others have pay-as-you-go packages. If you opt for a fixed plan, ensure there’s an option to top-up your data.
  • Travel duration: Ensure the eSIM's validity period aligns with your travel plans to avoid prematurely losing access to eSIM services.
  • Tethering capability: Check if the eSIM provider allows tethering, i.e., letting you share your device's data connection as a mobile hotspot.
  • Price: Compare eSIM prices to find the most affordable option that matches your budget.

How we tested and ranked these eSIMs for South Korea

I conducted extensive research to find the best eSIMs for South Korea. I also worked with the Cybernews team to run tests on different eSIMs, assessing their coverage, network speeds, data plans, price, customer support options, and more. Here’s a quick look at the criteria I used to pick the best South Korea eSIMs:

  • Coverage in South Korea: My first requirement for selecting the best eSIM for South Korea is extensive coverage in the country. I checked which local carriers each eSIM works with and picked providers with coverage across the country. I also included eSIMs with coverage in neighboring countries to ensure seamless connectivity if you’re traveling across the region.
  • Network: The type of network your eSIM supports determines the speed of your connection, so I picked eSIMs that support 5G, 4G, 3G, and LTE. This guarantees relatively good speeds in South Korea.
  • Data plans: The ideal data plan for each traveler differs depending on the duration of your trip and your data consumption needs. I assessed the data plans each eSIM offers and picked providers with the widest array of plans. I made sure to include eSIMs that have different types of plans, both prepaid and pay-as-you-go options.
  • Compatibility: eSIMs are generally compatible with newer smartphones. However, some eSIMs may not work with particular devices. I chose eSIMs that work with a variety of different devices to ensure easy installation.
  • User-friendliness: I assessed the user-friendliness of different eSIMs, paying particular attention to their apps and activation process. All the eSIMs I picked are easy to install and have user-friendly apps.
  • Price: I looked at the prices of different eSIMs and compared the features they offer. I picked the eSIMs that offer the best prices and have an array of useful features.
  • Customer support: I looked at each eSIM's customer service channels and selected those that responded quickly via email and live chat.

What is the best mobile network in South Korea?

The jury’s still out on the best mobile network in South Korea. However, two companies that are often cited among the leading network providers in the country are KT (Korea Telecom) and SK Telecom.

KT is a pioneer of 5G technology in South Korea, while SK Telecom is known for its AI integration. While they both offer high-speed internet, SK Telecom is known to have slightly better speeds.

Most of the eSIM providers I’ve highlighted above work with either or both companies. These network providers boast 100% nationwide coverage in South Korea and support 5G in the country.

Pros and cons of using eSIM in South Korea

There are many benefits to using an eSIM for travelers in South Korea, but there are also some drawbacks. Generally, the advantages outweigh the disadvantages, but it’s important to know the potential downsides of using an eSIM in South Korea. With that said, here are some pros and cons to consider:

Pros of using an eSIM in South Korea

  1. Instant Internet access: Using an eSIM means you get access to the internet the moment you arrive in South Korea.
  2. Keep your phone number: You don’t have to remove your regular SIM card to use an eSIM. This means you can keep your number and use the eSIM for data.
  3. Save money: eSIM plans are considerably cheaper than roaming costs, so using an eSIM can help you save money. This is one of the biggest reasons why many travelers choose an eSIM in South Korea.

Cons of using an eSIM in South Korea

  1. Compatibility issues: Many older phones (made before 2018) don’t work with eSIMs. If you’re not using an eSIM-compatible phone, you can’t use an eSIM during your trip to South Korea.
  2. Difficulty switching devices: Unlike physical SIM cards that you can easily take out from one device and insert into another, the only way to switch an eSIM between devices is to go through the entire installation and activation process from scratch. This can be a major inconvenience if you damage your phone while traveling.

Does my phone support eSIM?

Many newer iPhones and Android devices support eSIMs, but it's best to confirm if your specific device is compatible with eSIMs. Read on to find out how to check if your phone supports eSIM.

eSIM compatibility on iPhone

iPhone models, including iPhone XS, XS Max, XR, 11, 11 Pro, 11 Pro Max, SE (2nd generation), 12, 12 mini, 12 Pro, and 12 Pro Max, work with eSIMs.

You can activate eSIMs through the cellular settings menu. If you’re still unsure if your iPhone supports eSIMs, ​​consult your iPhone’s specifications or contact the eSIM provider.

eSIM compatibility on Android phone

eSIM compatibility on Android phones varies by model and manufacturer. Many newer Android devices, such as Google Pixel phones, Samsung Galaxy series (S20, S21, and above), and select devices from other manufacturers, support eSIM technology. You can typically activate your eSIM through the Network & Internet or Connections menu on your Android phone settings.

How to set up and activate the eSIM data plan for South Korea

It’s easy to set up and use an eSIM. Most providers have detailed instructions online explaining how to set up your South Korea eSIM. I’ll briefly explain the most important things to know below.

How to buy an eSIM

  1. Identify the provider and plan you want.
  2. Download the eSIM app or visit the provider’s website.
  3. Create an account and purchase a plan.
  4. You’ll receive an email with instructions on how to install your eSIM in South Korea.

Note: If you don’t find an eSIM activation guide on the provider’s website or app, I recommend contacting their customer service team for support.

How to activate an eSIM in South Korea

Installing and activating an eSIM is generally a straightforward procedure. Depending on the eSIM provider you’ve chosen, you may have one or more methods available to install and activate your eSIM.

eSIM providers usually have detailed instructions to guide users through the installation and activation process. Here are the main ways you can activate an eSIM on your phone:

  • QR code activation: This is arguably the most popular eSIM activation method. It involves scanning a QR code the eSIM provider shares with you. You’ll be asked to tweak your device settings, like making the eSIM your primary SIM and turning on data roaming.
  • App activation: Some eSIM providers allow you to install and activate your eSIM by clicking a button on their app. The process is mostly automated, but you may still need to set the eSIM as your main SIM card and turn on data roaming before it will start working.
  • Manual activation: This activation method is more technical than the others above. To activate an eSIM manually, you must input the eSIM details, like the activation code and SM+DP address, directly into your device’s settings.

Where to buy a prepaid eSIM card for South Korea?

You can buy an eSIM for South Korea from the website or app of your preferred eSIM provider. The process isn’t different from buying other items online. Simply scan through the eSIM provider’s site or app and pick your preferred eSIM plan for South Korea. Then, click to buy.

eSIM providers usually have multiple payment options, including debit/credit cards, PayPal, Apple Pay, and more. However, you may be required to create an account before you can buy an eSIM.

When to order/activate an eSIM card for South Korea?

While you can purchase and activate your eSIM at any time, I recommend setting it up just a day before you travel to South Korea. This is important as you may need internet access to install your eSIM. Also, if you activate your eSIM too early before you travel, it could expire before your trip ends, leaving you without access to the internet.

Keep in mind that some eSIMs are activated once you install the provider’s app, but others need to be connected to a local network before they start working. Generally, waiting until a day before you travel to activate your eSIM ensures you can get internet access as soon as you arrive in South Korea.

Things to know about using an eSIM card in South Korea

South Korea is one of the Asian countries with the most expensive mobile internet charges. Hence, an eSIM is a great way to avoid hefty prices. Here are a few things to know about using an eSIM in South Korea:

  1. Make sure your phone is unlocked: Locked phones are tied to specific mobile service providers, and you can’t use an eSIM on them.
  2. Make sure your phone supports an eSIM: Check if your phone supports eSIM technology. Not all mobile devices are compatible with eSIMs.
  3. Calling and phone number: Most eSIM plans don’t support calling or come with a phone number. While some eSIM providers offer phone numbers, they’re only for receiving calls and SMS.
  4. Activation timing: The validity of some eSIM cards begins after installation, while others start upon connecting to a supported network. Ensure you activate your eSIM card within the specified time frame.
  5. Activation process: Check which activation methods your eSIM supports. The most common eSIM activation methods are QR code scanning, app-based activation, or manual activation.

How to make calls with an eSIM in South Korea

Would you like to make calls and send SMS in South Korea using your eSIM? Here are the options available to you:

  • Select a provider with a calling option: Look for an eSIM provider that offers a phone number you can use to make calls. Airalo and aloSIM both support calling and texting.
  • Use a domestic SIM card: Use your existing physical SIM card to make calls while reserving the eSIM solely for data. Remember that international calls are more expensive.
  • Use VoIP apps: Explore Voice over Internet Protocol (VoIP) apps such as WhatsApp, FaceTime, or Google Voice. These apps use data to make calls over the Internet, providing a cost-effective alternative to traditional cellular networks.

Final thoughts on the best eSIMs for South Korea

Getting an eSIM for South Korea allows you to stay connected and avoid the hassle of having to purchase a physical SIM card in the country.

Saily is the best eSIM for South Korea, in my opinion. It offers flexible data plans, competitive prices, and easy activation. Plus, Saily has coverage across South Korea and other countries in the region, so you can stay connected throughout your trip without breaking the bank.
