Why use an eSIM in South Korea
- Cheaper than roaming
- Carrier roaming bills a daily fee whether you use data or not. A prepaid plan bills once, upfront.
- Working the moment you land
- No hunting for a shop, no passport registration, no airport queue at midnight.
- Your number stays yours
- Dual SIM keeps calls, texts, and WhatsApp on your home line while data rides on Jelly.
Getting online in South Korea
Buy a plan and scan the QR code from your email while you still have Wi-Fi.
Land in South Korea, switch the Jelly line on, and set it as your data line.
Turn off data roaming on your home line so your carrier cannot bill you.
South Korea eSIM questions
When does my South Korea plan start counting?
Validity starts when the eSIM first connects to a network in South Korea, not when you buy it. Installing early costs you nothing.
Can I make calls in South Korea?
Jelly plans are data plans. Calls work over WhatsApp, FaceTime, or any app you already use, and your home number stays reachable on your other SIM.
Can I tether a laptop in South Korea?
Yes on most compatible phones. Tethering uses data quickly, so pick a larger plan if a laptop is coming with you.
What if I run out of data in South Korea?
Top up from your dashboard. The top up applies to the eSIM already installed, so there is nothing new to scan.
Visiting more than South Korea?
A regional plan covers multiple countries on one eSIM.
