Pros:

  • Connects to the premium KT network for reliable LTE coverage.
  • Unlimited data plans available for heavy users.
  • Optional Yabb app for calls, since the eSIM includes data only.
  • Extremely competitive pricing with no hidden fees.
  • Unrestricted personal hotspot/tethering.

Cons:

Airalo

Airalo is a well-known option. Their plans often utilize LG U+ or KT. While using LG U provides good city coverage, it might not be as robust in remote areas as KT or SK Telecom. Prices start higher than eSIM4, but they are a reliable alternative if you need specific unlimited data plans.

Jetpac

Jetpac offers affordable entry-level plans. It’s a good budget option if you don’t need a massive amount of data. However, for longer trips requiring unlimited data, their pricing can be steeper than competitors.

Nomad

Nomad eSIM is user-friendly and offers various plans with unlimited data. They primarily connect to KT. While reliable, the pricing is generally higher than eSIM4 for the same amount of data.

Buying Guide: Everything You Need to Know

How to Choose the Right Plan

Deciding between a SIM or eSIM is easy: eSIM is far more convenient. When choosing a plan, consider how much data you need depending on your travel style.

  • Light Travel: If you only use maps and messaging, a smaller plan suffices.
  • Heavy Usage: If you stream video or work remotely, you might need an unlimited plan.
  • Duration: Ensure the validity matches your trip length.

Coverage and Network Speeds

South Korea boasts excellent infrastructure with widespread 4G and 5G networks. While many travel eSIMs focus on LTE, the speeds are often comparable to 5G in other parts of the world.

Whether you are connecting via KT and SK Telecom or using LG U, coverage in major cities like Seoul is flawless. Your eSIM ensures you have access to these top-tier networks. Note that while locals use LTE and 5G, most tourist eSIMs provide stable LTE which is sufficient for all internet access needs.

Step-by-Step: How to Install Your eSIM

It is best to install your eSIM before you fly.

Step 1: Purchase

Select the amount of data you need on the eSIM4 South Korea page.

Step 2: Install

  • You will receive a QR code via email.
  • On iPhone: Go to Settings > Cellular > Add eSIM.
  • On Android: Go to Settings > Network and internet > SIMs > Add eSIM.
  • Scan the code to install and activate the profile.

Step 3: Activate

  • Activate the data roaming when you land.
  • Ensure your phone settings have the new eSIM for data selected.

Making Calls and Sending SMS

As mentioned, most travel eSIM plans don’t include a local number. This means you cannot make traditional voice calls.

Using Yabb for Calls

eSIM4’s Yabb app bridges this gap. It allows you to use your internet access to call landlines and mobiles. This effectively gives you the utility of a local phone number without the roaming costs.
