The value we create
Internet on your trip should be easy, affordable and work right away. Forget searching the airport for a SIM card, or being shocked by a huge roaming bill. A Yeohaengyusim eSIM gets you online within minutes, wherever you are in the world.
What makes Yeohaengyusim different
Our eSIM plans cover over 200 countries, and you receive your QR code as soon as you pay. Whether it's unlimited data for a quick weekend away or a good-value plan for a stay longer than a month, there's an option to match how you travel.
What is eSIM technology?
An eSIM is a SIM that lives digitally inside recent smartphones. Nothing physical needs swapping: scan one QR code and your data plan is set up instantly. It runs side by side with your current SIM, so your Korean number stays active while you use data overseas.
