How a travel eSIM works

When you purchase an eSIM for your South Korea trip, you're essentially buying a digital SIM card that replaces the physical one in your phone. This allows you to stay connected without having to carry multiple SIM cards or worry about roaming charges.

What to expect from your provider

Your eSIM provider will give you access to their network and allow you to make calls, send texts, and browse the internet just like you would with a traditional SIM card. However, since it's a digital service, you won't receive any physical materials or need to worry about physically switching out SIM cards.

  • Some providers may also offer additional features such as international calling plans, data-only options, or even travel insurance.
  • Be sure to check the provider's coverage and network quality in South Korea before making your purchase. eSIM for Europe: how to choose and set up a travel eSIM provides more information on choosing the right provider for your needs.

What you need before you buy an eSIM

Check your device's compatibility

Before purchasing an eSIM for South Korea travel, ensure that your phone or tablet is compatible with the type of eSIM you plan to use. Not all devices support eSIM technology, so it's essential to check your device's specifications beforehand.

Carrier lock considerations

If your device is carrier-locked, meaning it can only work on a specific network, ask your current carrier to unlock it. A travel eSIM provider cannot unlock it for you. Travel eSIMs work on unlocked phones, so check your lock status before you buy.

  • Check your device's manufacturer website for compatibility information
  • Research the eSIM provider's policies on carrier-lock status and unlocking phones
  • Consider purchasing an eSIM-enabled device if yours is not compatible or locked

  • Choose the correct country code for South Korea (+82) and enter the phone number.
  • Set up any additional features or services provided by your carrier.
