Compare Plan Details
Do not judge speed or usage terms from the word “unlimited” alone. Check whether the plan is data-only, whether it supports incoming and outgoing calls and texts, how usage days are counted, and whether your device is restricted.
KT Korea eSIM · 11 GB per day, then 5 Mbps
Klook · KT
This is a 4G LTE plan on the KT network. The product page lists validity options of 1–90 days, unlimited-data options, and hotspot sharing.
Data, Calls and Texts
The plan option is labelled “data + incoming calls/texts,” but its description says it is data-only and that calls and texts are incoming only. To receive SMS, the passport details entered at purchase must exactly match the identity-verification details after arrival; otherwise, SMS may not be received. Outgoing calls and texts are not included. The page says you can continue using data at 5 Mbps after using 11 GB in a day. Check this speed condition rather than relying on the word “unlimited.”
Device Compatibility
Only devices that support eSIM can use this plan. Check eSIM support for your specific device with its manufacturer before purchase.
Validity and Activation
Options of 1–90 days are listed. Check the booking screen for the selected validity and when use begins.
Cancellations and Refunds
The page states that cancellation or a refund is not available for compatibility issues. For other reasons, check the terms for the selected option and the booking screen.

SK Telecom Unlimited eSIM · T-money Card Option
Klook · SK Telecom
This is an SK Telecom 4G LTE eSIM (the product information lists speeds up to 100 Mbps). Options of 2–90 days are listed. Plans of three days or longer include a T-money card collected at an SKT roaming center at the airport.
Data, Calls and Texts
Data is included by default. The listing says calls and texts can be used after passport identity verification and an additional top-up; without verification, only data is available. Verification is available daily from 08:00 to 22:00 after arrival, but holders of Korean passports cannot complete verification. Hotspot sharing is not supported. The plan is listed as unlimited data, with a notice that the carrier’s fair-use policy may impose speed or usage limits.
Device Compatibility
Check that your device supports eSIM and is carrier-unlocked. The listing says some Hong Kong and China versions of dual-SIM models cannot be used.
Validity and Activation
Options of 2–90 days are listed. Wi-Fi is required for setup, and usage days begin counting from arrival in Korea, according to the listing.
Cancellations and Refunds
The listing says refunds or cancellations are unavailable for eSIM compatibility issues. Check the booking screen for other refund terms for your selected option.

Frequently Asked Questions
What should I check before buying an eSIM?
Make sure your phone supports eSIM and is carrier-unlocked. Some plans may exclude particular models. Installation may require an internet connection, so read each product’s activation instructions.
Can I make regular calls and send texts with a Korea eSIM?
It depends on the plan. The KT listing limits service to data and incoming calls/texts; receiving SMS requires the purchase details to match the passport verification details. The SK Telecom plan requires identity verification after arrival (Korean passports excluded) and a top-up for calls and texts; verification is listed as available from 08:00 to 22:00. Check the Trip.com option for calls and texts.
Can I receive phone-number verification texts for services such as food-delivery apps?
The plan’s description of calls and texts does not guarantee phone-number verification for third-party services, including food-delivery apps. Whether a verification code can be received depends on the service and carrier terms; check with the service.
Where can I check eSIM prices and refund terms?
Prices and terms may vary by validity and data allowance. Before paying, check the seller’s product page for the latest price, selected option and refund deadline.
