Is it right for your trip?

Buy this one if
  • You want data that does not run out, from an overnight stop to a three-month stay.
  • You navigate, stream and browse on your phone with no allowance to watch.
  • You use KakaoTalk, WhatsApp or similar apps instead of a cellular number.
Choose another plan if
  • You need a Korean phone number for bookings, deliveries or verification codes.
  • You need to make or receive ordinary cellular calls or SMS.
  • You need to receive bank or service one-time passcodes by SMS.
  • You need a guaranteed minimum speed rather than an uncapped allowance.

About this plan

No number, calls or SMS

This plan cannot receive one-time passcodes by SMS and cannot place or take ordinary phone calls. Keep your home SIM available if you need those.

Unlimited is not a speed promise

There is no total allowance, but the speed you get depends on coverage, network conditions and your device.

Validity runs in 24-hour blocks

The clock starts at activation, so a plan bought for a single day ends 24 hours later rather than at midnight.

Compatible unlocked phone required

Confirm eSIM support and carrier-unlocked status before purchase.

Install on the final device

The QR code is for a single installation. It cannot be reinstalled or moved to another device.
