Setting up your South Korea eSIM
- Check your phone is unlocked and supports eSIM (dial *#06# and look for an EID).
- Buy a South Korea or regional plan and install it on Wi-Fi before you travel.
- On arrival, switch the eSIM line on, enable data roaming for that line only, and set it as your mobile-data line.
- Keep your home SIM on for calls/SMS if you need them, but turn off its data roaming.
FAQ
What is the best eSIM for South Korea?
It depends on how long you're staying and how much data you need. Airalo, Yesim and Saily all sell South Korea plans; compare their live prices and data caps using the links on this page, and check that unlimited plans don't have a low daily speed cap.
Do I need an eSIM or a local SIM in South Korea?
An eSIM is easiest if your phone supports it: you can install it before you leave and be online as soon as you land in South Korea. A physical local SIM can be cheaper for long stays but usually means a shop visit and ID.
When should I install my eSIM for South Korea?
Install it at home on Wi-Fi a day or two before departure, but only switch the line on (and enable its data roaming) when you arrive, so the plan's validity doesn't start early.
What currency, plug and time zone does South Korea use?
South Korea uses the South Korean won (KRW). Plug types and voltage: C, F · 220 V. Local time zone: Asia/Seoul.
