Korea Prepaid eSIM 10GB – 15-Day or 30-Day Plan
Choose a 15-day or 30-day Korea prepaid eSIM, receive the QR details by email after purchase, and get connected without physical shipping or passport-copy upload.
After checkout, watch for the QR email, install on an unlocked eSIM-ready phone, keep stable Wi-Fi available, and save the email until setup is complete.
This plan includes 10 GB of high-speed LTE. After the allowance is used, data continues at 128 kbps for essentials like maps, messages, and ride-hailing.
Refund eligibility applies only before eSIM installation; USD 2 verification fee remains non-refundable.
Need Korea data now but may stay longer? Start with prepaid first, then review the separate KT long-stay option only after you have a Residence Card and a Korean bank card or account, because that conversion must happen within 60 days. Review KT long-stay requirements.

Honest answers
Questions about this plan
Does this eSIM come with a Korean phone number?
No — this is a data-only eSIM. It gives you fast mobile data on KT’s network, but no Korean number, so it cannot receive Korean SMS verification codes. If you need a real number for KakaoTalk, banking or 본인인증, choose a SIM with a Korean number instead.
When should I activate my Korea eSIM?
Install it before you fly on Wi-Fi, but activate it only after you land in Korea — your validity period starts when you activate, so you don’t waste any days.
Which phones work with a Korea eSIM?
Most recent unlocked phones support eSIM — iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Your phone must be carrier-unlocked. Phones bought in mainland China or Hong Kong may not support eSIM.
Can I get a refund?
Yes — you can request a refund any time before you install or activate. If a QR code cannot be delivered or activated due to a service fault, email [email protected] for a resolution.
