KT lists 4 options for this: Daily roaming Basic; Daily roaming Plus and Daily roaming Premium, and more on this page. Prices without a figure depend on your plan, so check KT's official page. Confirm your destination is in the zone before you travel.
Before you land, open Settings and turn Data Roaming off for your KT line (iPhone: Mobile Service or Cellular; Android: SIMs or Mobile network). Turn off automatic data switching too. To avoid calls and texts being charged, turn the KT line off or use Wi-Fi calling where KT allows it.

HOW WE CHECK
The price, currency and how it is charged were read from the operator's own website on the date shown.
The operator explains its roaming rules, but not as one fixed price — for example, inclusive roaming that depends on your plan.
The plan exists, but its price depends on your contract or destination. Use the official link to see yours.
Recorded in an earlier research pass and not re-checked yet. We show the plan name and terms, never the old price.
A blank price means we could not verify one — never that it is free. Prices include or exclude tax as the operator publishes them. Snapshot: 25 October 2026. Logos are trademarks of their owners and identify each network only; Graba SIM is not affiliated with these operators.
