South Korea eSIM cost calculator: what your trip actually costs

South Korea eSIM cost calculator

Enter how long you stay and how much data you expect to use. The table shows what each provider actually charges for that trip, what you get, and how many days you end up paying for but not using.

Rows are in a fixed order by provider. That order is not a ranking.

The two price on different axes. Airalo sells a fixed ladder of trip lengths and a grid of data caps. Yesim sells unlimited by the exact day, so a 12-day trip costs 12 days rather than a 15-day package.

  • Airalo · Network: SK 5G
  • Airalo · Speed limit on unlimited packages: Unlimited means unlimited until 3 GB in one day. After that the speed drops to 1 Mbps for the rest of that day, then resets.
  • Yesim · Yesim does not publish which network it uses.
  • Both are data only. Neither gives you a local phone number, so if you need one for calls, deliveries or SMS codes, an eSIM of this kind is not the answer.
