South Korea eSIM plans start at $1.49. We currently offer 29 different plans for South Korea, so you can pick the data allowance and validity that match your trip instead of paying for a fixed bundle.
Instantly. As soon as your payment is confirmed, the QR code is emailed to you and appears in your account. There's nothing to ship and no counter to queue at. Install it over Wi-Fi before you fly.
Validity starts when the eSIM first connects to a network at your destination, not when you buy it. That means you can install it at home days before you travel and still land in South Korea with your full allowance intact.
Our South Korea plans run from 1 to 30 days from activation, so you can match a short city break or a longer trip.
No. An eSIM is a second, digital line, so your existing SIM stays in the phone. Keep your usual number active for calls and texts and use the travel eSIM for data. Just make sure mobile data is set to the eSIM to avoid roaming charges.
No, our travel eSIMs are data-only. There's no local number for regular calls or SMS, but WhatsApp, iMessage, FaceTime and any other app that works over data keep running on your existing number.
Yes. Plans marked "Top-up" can be recharged from your account without installing a new eSIM or scanning another QR code, handy if your trip runs long.
Your phone needs to support eSIM and be carrier-unlocked. Most handsets from 2019 onwards qualify: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, among others. Dial *#06# and look for an EID number: if one appears, your phone supports eSIM.
