South Korea is a popular stop for digital nomads, remote workers, and backpackers, offering high-tech cities, cultural heritage, and a solid infrastructure for remote work. Whether you’re working from a coworking space in Seoul, experiencing the creative energy of Busan, or taking a weekend escape to Jeju Island, staying online is essential. Thanks to eSIMs, you can now enjoy seamless mobile internet without the hassle of physical SIM cards.

I have to admit that in my first year as a digital nomad, I was hesitant to use eSIMs, but now after giving them a go, I don’t know what I thought the problem would be.

In this post, we’re highlighting our 2 eSIM recommendations for South Korea, covering Ubigi and eSIM4Travel, chosen for their affordability, ease of use, and reliability across the island. We’ve also included a helpful directory of other eSIM providers, as well as for other locations around the world.

What is an eSIM, and Why Should You Use One in South Korea?

An eSIM, which is actually short for embedded SIM, is a digital SIM card built into your phone or device. Instead of inserting a physical card, you download an eSIM profile from a provider, which gives you access to a mobile network in your chosen country or region (depending on what you choose).

Why Use an eSIM in South Korea?

  • Convenience: No need to visit shops or deal with local SIM cards.
  • Cost-Effective: Avoid expensive roaming fees from your home provider.
  • Flexibility: Easily switch between eSIM providers or plans.
  • Reliability: Get a strong connection in rural areas, and even on islands.

Recommended eSIM Providers for South Korea

2. eSIM4Travel: Best price for basic usage

While Ubigi is excellent, eSIM4Travel has become my go to provider. I’ve used it on multiple trips, and it has always been reliable. Plus, their customer support is fantastic if you ever run into issues.

What Makes eSIM4Travel Stand Out?

  • Clear Instructions: Their setup guide is easy to follow, even for first-time eSIM users.
