Which South Korea eSIM plan should you choose?
Start from how you use your phone when you travel, then match a plan to the length of your trip:
- Maps, messaging and email use little data. For a short trip, a few gigabytes is usually enough.
- Social media, photos and video calls use much more. Pick a larger allowance or a longer plan.
- Streaming, hotspot for a laptop or working remotely is where unlimited plans or the largest allowances make sense.
- Validity has to cover your whole stay. If you are travelling for two weeks, a 7-day plan will run out halfway.
Our fixed-data plans for South Korea run from 1 GB to 50 GB, valid from 1 day to 30 days. Each plan page shows the exact allowance, validity and price before you buy.
Unlimited plans come with a daily high-speed allowance (1 GB to 3 GB per day on the plans we stock). Once you use it, the plan keeps working at reduced speed until the allowance resets the next day — the plan page shows the details.
These plans are data-only — they do not come with a local phone number. You can still call and message over the internet with apps such as WhatsApp, FaceTime or Telegram.
Roaming in South Korea: why an eSIM helps
South Korea is outside the EU, so EU "Roam Like at Home" rules do not cover it. Without an eSIM, your home operator’s own roaming rates apply — check them before you go, or use a local data plan like the ones above.
Does my phone support an eSIM?
Your phone needs two things: eSIM support and no carrier lock. Most recent phones have eSIM — iPhone XS, XR and newer, and most recent Google Pixel and Samsung Galaxy models — but some regional or budget versions do not.
- Check for eSIM: look for an "Add eSIM" or "Add mobile plan" option in your phone’s mobile or SIM settings.
- Check the lock: a phone bought on contract may be locked to your operator. Ask them to unlock it before you travel.
