STEP 1

How many days?

Pick your days, then 4G or 5G. Every plan comes with unlimited data; plans of 2 days or more also include a 010 number. 1‑day plans are data only.

Delivery: QR code by email, usually within minutes of payment. Plan validity: 1 to 90 days, counted from the first connection in Korea. Install within 6 months of receiving the QR code.

STEP 2

Check your phone

Takes 30 seconds. Do it before you pay — a phone that can’t use eSIM is not a reason for a refund.

Not sure? On iPhone: Settings → General → About → look for “Digital SIM” / “EID”. On Android: dial *#06# and look for EID. Or bring it to a store — we check it free.

IMPORTANT

Read before you buy

Nine things our store staff get asked about most. Two minutes now saves a problem when you land.

  1. 01
    No refund once the QR is sentAn eSIM is digital and can be copied, so it can’t be returned after delivery. Cancel before it’s sent for a full refund.
  2. 02
    Install it only once — don’t delete itEach QR code works a single time. If you remove the eSIM from your phone, it can’t be reinstalled.
  3. 03
    Your phone must be eSIM‑ready and unlockedCheck step 2 above. An incompatible phone isn’t a ground for refund.
  4. 04
    Install on Wi‑Fi, before you flyYou need an internet connection to download the eSIM, so do it at home. Install and connect within 6 months of receiving the QR code.
  5. 05
    Your plan starts when it first connects in KoreaInstalling early is fine. Validity is counted in hours from the first connection — a 7‑day plan runs for 168 hours. Plans can’t be extended.
  6. 06
    Turn on the line and data roaming on arrivalSet the Travel SIM line as your mobile data line and switch data roaming ON for it.
  7. 07
    Check your spam folderThe email comes from MEGA TELECOM with your QR, SM‑DP+ address and activation code. Double‑check your email when ordering.
  8. 08
    Calls and texts are incoming onlyPlans of 2 days or more get a 010 number that receives calls, texts and verification codes. 1‑day plans are data only. Outgoing calls and texts need a separate top‑up.
  9. 09
    You register your passport details yourselfTo use the 010 number, enter your passport or residence card details on the operator’s registration page (link in your QR email). We don’t ask for or keep your ID.

Q&A

Questions travellers ask us

Can’t find yours? Message us on WhatsApp or KakaoTalk, or call 1644‑4570.

When will I receive my eSIM?

Usually within a few minutes of payment, by email. If it hasn’t arrived in 30 minutes, check your spam folder, then contact us on WhatsApp or KakaoTalk.

Can I install it before I travel?

Yes — we recommend it. Install on Wi‑Fi at home. Your plan only starts when the eSIM first connects to the network in Korea. Install and connect within 6 months of receiving your QR code.

Is the data really unlimited?

Yes. Data is unlimited for the whole length of your plan, on the 4G or 5G plan you choose. On 5G plans, hotspot (tethering) is limited to 1 GB per day. Speed and benefits are those the network operator provides for the plan.

Do I get a Korean phone number?

Plans of 2 days or more include a 010 number. Once you register it on the operator’s page (the link is in your QR email), it receives calls, texts and SMS verification codes. 1‑day plans are data only. Outgoing calls and texts need a separate top‑up — or use messaging apps on your data.

Can I keep my home SIM active too?

Yes. Most phones run two lines at once. Keep your home SIM for calls and texts, and set Travel SIM as your mobile data line.

My phone says “No service” after landing. What do I do?

Make sure the Travel SIM line is turned on, set as the data line, and data roaming is ON for it. Restart the phone. Still stuck? Walk into any of our stores and we’ll fix it with you.

I deleted the eSIM by mistake. Can I get it back?

Unfortunately not — each QR can be installed only once and deleted eSIMs can’t be restored. You would need to buy a new one.

Can I get a refund?

Full refund if you cancel before the QR code is sent, or if the fault is ours. After the code is sent, it can’t be cancelled or refunded — including when a phone turns out not to support eSIM or is carrier‑locked.

Can I extend my plan?

Plans can’t be extended. Buy a new plan for the extra days. If you’re staying longer term, ask us about a prepaid SIM in your own name or a postpaid plan.

Where can I get help in person?

At any of our 4 stores in Seoul, daily 10:00–19:00. Our Itaewon Global Store speaks English, Spanish, Vietnamese and Korean. No appointment needed — bring your phone.
