Terms of Sale

1. Who we are

MEGA TELECOM Co., Ltd. (“we”, “us”), a KT Authorized Dealer registered in the Republic of Korea.
Business registration no. 210-81-71533 · Mail-order sales registration no. 2024-Seoul Jung-gu-1432
CEO: Lee Jae-chul · 134 Dasan-ro, Jung-gu, Seoul, Republic of Korea
Customer centre: 1644-4570 (daily 10:00–19:00) · Email: manager@ktmega.com

2. What these terms cover

These terms apply when you buy a MEGA Travel SIM prepaid data eSIM from us, either at one of our stores or through this website. They do not cover KT postpaid subscriptions, home internet, or our free consultation service, which are governed by separate agreements.

3. What you are buying

You are buying a prepaid, data-only eSIM profile that runs on the SK Telecom network, supplied through authorized distributors. We resell it; the network service itself is provided by the mobile operator, not by us. The plan you choose determines the validity period and the data speed.

Voice calls and SMS are not included by default. A Korean mobile number is issued with the profile, and you may activate voice and SMS yourself through the operator’s registration page at https://krsim.net/esimreg. Registration is handled by the operator and is subject to the operator’s own terms and identity-verification rules.

4. Your device must be compatible

Your device must meet all three of these conditions:

• it supports eSIM;
• it is not carrier-locked to another mobile operator;
• it runs iOS 17.4 or later, or Android 10 or later.

5. The profile can be installed only once

An eSIM profile can be downloaded one time only. If you delete it from your device, reset your device, or the download fails because you cancelled it, the profile cannot be restored or re-issued, and no refund is due. Do not delete the eSIM after installing it.

6. Price and payment

Online prices are shown and charged in US dollars (USD) and include VAT where applicable. The amount charged is the USD price displayed at the time of your order; any approximate Korean won (KRW) amount shown next to it is for reference only. Online payments are processed by our payment provider, Toss Payments, by card or PayPal. We do not store your full card number.

7. Delivery

For store purchases, we deliver the QR code and activation details on screen, on paper, or by email, as you choose. For online orders, we send them to the email address you give us.

Please check your spam folder before contacting us about a missing email; we will resend it free of charge.

8. Validity and expiry

Your plan’s validity period starts when the eSIM first connects to the network, not when you buy it or install it. Validity is counted in hours: a 5-day plan runs for 120 consecutive hours from that first connection, a 7-day plan for 168 hours, and so on. The eSIM must be installed within 6 months of receiving the QR code; after that the code may no longer work and no refund is given. Unused data and unused time are not refundable and cannot be carried over.

9. Acceptable use

You may not resell the eSIM, use it for spam, fraud, or any unlawful purpose, or use it in a way that damages the network. The operator may suspend the service if you do. We may refuse or cancel an order where we reasonably suspect fraud or abuse, and we will refund you in full if we do.

10. Our responsibility to you

We are responsible for delivering a working, unused activation code. We are not responsible for the mobile network itself (coverage, speed, outages), for your device, or for anything the operator does under its own terms. Nothing in these terms limits liability that cannot be limited by Korean law, including liability for death, personal injury, or intentional or grossly negligent conduct. Where our liability is limited, it is limited to the amount you paid for the eSIM.

11. Governing law and disputes

These terms are governed by the laws of the Republic of Korea. If something goes wrong, please contact us first — most things are resolved that way. You may also apply to the Korea Consumer Agency (www.kca.go.kr) or the Korea Fair Trade Mediation Agency for dispute mediation. If a court is needed, the court with jurisdiction over our head office will hear the case, unless the law mandatorily gives you the right to sue in the courts of your place of residence.

12. Changes

We may change these terms. If a change affects your rights, we will post the new version on this page at least 7 days before it takes effect (30 days if the change is unfavourable to you). The version in force when you ordered is the one that applies to that order.
