Prepaid eSIM for South Korea

Pay once, use anywhere

No monthly billing, no credit check, no contract. Buy the data you need for South Korea, scan the QR, travel.

Predictable cost

Carrier post-paid roaming bills can balloon to $200+ for a single week abroad. Prepaid eSIMs are a fixed cost — you know exactly what your trip data will cost before you leave.

Great for gifts and groups

Prepaid eSIMs are easy to buy on someone else's behalf — for parents travelling abroad, kids on a school trip, or work teams flying together.

How does a prepaid eSIM differ from postpaid?

Prepaid means you pay the full cost upfront and use only what you bought — no monthly bill, no credit check, no auto-renewal. Postpaid (your home carrier roaming) bills you after the fact, often with surprise charges.

Can I add more data later in South Korea?

Yes — buy another prepaid plan from LTE.app at any time. Top-ups activate immediately and stack with your remaining balance on supported carriers.

Is prepaid safe for kids or elderly travelers?

Yes. Because the cost is fixed and there is no link to your home account, prepaid is the safest option for travelers who would not notice an overage charge.

Do I need ID to buy a prepaid South Korea eSIM?

No. LTE.app prepaid eSIMs require no ID, no passport scan, and no local registration. Pay, receive QR by email, scan, done.
