How much data do you need for South Korea?

Pick the band that matches your trip. Top-up is available on most plans if you run low.

3 GB

Light: maps, translation and messaging

Around 3 GB covers a short city break spent mostly on Naver Map, Papago translation and KakaoTalk. Korea has fast public Wi-Fi almost everywhere, so light users rarely burn through much.

5 to 10 GB

Typical: social, browsing and some photos

5 to 10 GB suits a week or two of everyday use, posting photos, browsing and checking transit, with headroom for the odd video call home. This is the sweet spot for most South Korea trips.

20 GB+

Heavy: video, hotspot and remote work

20 GB or more fits streaming, tethering a laptop and working on the road. If you would rather not count gigabytes, an unlimited plan gives a generous daily full-speed allowance before the speed eases off.

Why Simzora for South Korea

No hype, just how the service actually behaves once you land.

Roams on Korea's strongest networks

Plans connect to local partner networks, so you get fast 5G across Seoul, Busan, Jeju and deep into the subway tunnels. Signal only really thins out on remote mountain trails like Seoraksan.

Honest per-GB pricing

You buy a plain amount of data at a visible per-GB price, not a vague unlimited day rate. Standard plans top up without a new QR code if you run low mid-trip.

Ready before you land

The eSIM arrives by email within minutes, so you can install it on home Wi-Fi and connect the moment you reach the arrivals hall at Incheon or Gimpo. It is data-only, so keep your own SIM in for bank OTP codes.

Best eSIM for South Korea, FAQs

Straight answers to the questions travellers ask most.

Which eSIM is best for South Korea?
For most travellers, a mid-size Simzora plan roaming on local partner networks is the best mix of price and coverage. Pick 5 to 10 GB for a typical trip, less for a light one, and 20 GB or an unlimited plan if you stream or tether a lot.
How much data do I need for South Korea?
Korea has fast public Wi-Fi almost everywhere, so many people manage on 3 to 5 GB for a week of maps and messaging. If you stream video or use a hotspot daily, plan for 10 to 20 GB or an unlimited plan.
Can I still get bank OTP codes and use the subway apps?
The eSIM is data-only, so keep your own SIM active in another slot for bank OTP codes and calls. Everything data-based, Naver Map, Papago, KakaoTalk and the subway apps, works normally over the Simzora line.
