South Korea eSIM vs home-network roaming

Buy a data-only South Korea eSIM from STISH GO. 5G, hotspot, and a visible fair-use policy on unlimited plans. Every paid plan includes Emergency 500 MB on the same eSIM so you never get stranded without internet.

STISH GO sells data-only eSIM for South Korea — no phone number, SMS, or voice. You keep your home SIM for calls and use the travel line for internet. 8 live plans are published for this destination right now, starting from €3.99. 5G is available on listed plans. Hotspot / tethering is allowed where the card says HOTSPOT.

Validity starts on first use in South Korea unless the card says it starts at install. That matters if you install on Wi-Fi at home a week before the flight: fixed-GB plans typically do not burn days until you land. Unlimited day-pass style plans are the exception — we print that on the card.

Unlimited South Korea eSIM is never uncapped. Fair use: 2 GB/day at full speed, then slower until the next day. If you need a hard GB cap instead, pick a fixed plan so you can see €/GB.

Operators we currently list: SK Telecom, KT. When two wholesalers offer the same GB and days, the store highlights the cheaper one and shows the other operator as “same GB, +X”. Emergency 500 MB sits on the same eSIM if the main bucket hits zero — WhatsApp, maps, rides, and the STISH GO app.

Home-operator roaming in South Korea is often €2–€12 per day or a steep per-MB rate once the daily pass ends. A 1 GB / 7 days STISH GO plan at €3.99 is a known cost before you fly. Use Dual SIM: home number stays reachable, data goes to STISH GO. Turn roaming ON only on the travel line.

Top-up keeps the same ICCID when the provider allows it — no second QR. Trip planner compares N local packs vs one regional vs one global if South Korea is one stop among several. Compatible phones: iPhone XS and newer, Pixel 3+, Galaxy S20+, and other eSIM handsets in our device list. Carrier-locked phones may refuse a travel eSIM.
