South Korea travel data eSIM
What is a South Korea eSIM?
A South Korea eSIM gives you instant, data‑only connectivity the moment you land, letting you navigate bustling streets, check transit schedules, and translate menus without swapping physical SIMs. It works on your unlocked phone, so you keep your home number for calls and texts while staying online throughout your visit to the peninsula.
When you activate the eSIM in South Korea it connects to LG Uplus 5G and SKTelecom 5G networks. Your data allowance is drawn down from the selected plan, and you can use it for apps, maps, and online services while moving between cities or staying in one place.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operators does the South Korea eSIM use and what does that mean for a traveller?
The eSIM connects to LG Uplus 5G and SKTelecom 5G. This gives you access to the same networks that local residents use, so you can browse, map, and use apps just as they do.
Does the eSIM also work in a real neighbouring country of South Korea?
It is a single‑country plan valid only in South Korea. Regional plans are available if you need connectivity in nearby nations such as Japan.
Which plan size suits a trip to Seoul and Busan?
As a rough guide, the 5 GB 30‑day plan often fits a two‑city itinerary with moderate daily usage, while heavier users might consider the 10 GB option.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
