🇰🇷 korea esim data calculator
Korea eSIM
No GB to pick upfront. Top up the wallet, use data in Korea as you need it; afterwards we count what you actually used and charge whichever math comes out cheapest.
Get started →What a trip here roughly costs
Estimated over 5 days at about 1.5 GB a day — 7.5 GB total. An illustrative trip, not a commitment: you never have to decide upfront.
The gap comes from us combining plans for you. It is not a discount — it is two ways of pricing the same usage, and we charge the lower one.
- Lowest threshold
- $3.50 / 1 GB
- Per-GB rate
- $4.50 / GB
Your actual amount depends on what you actually use, settled over a 30-day window at the tariff disclosed before payment.
One wallet, no country to choose
There is no such thing as a "Korea plan" at soda. The same wallet works everywhere we cover — this page just spells out what Korea actually looks like.

How much data should I get for Seoul?
You don't size it. Navigate, scroll stories, hunt restaurants — we bill only what you used and cap it at the cheapest plan price.
Could I blow through a lot of money by accident?
Just set a cap: an alert at 80%, auto-pause at the limit, one tap to keep going. The budget stays in your hands.
