Set up before you fly
Buy in the Yesim app and install your QR code at home. Your plan activates automatically when you first connect to a local tower in South Korea.
Keep your existing number
Yesim runs as a second line alongside your home SIM. Your usual number stays active for calls and texts — Yesim handles data only.
Real-time data usage
Track exactly how much data you've used at any time in the Yesim app, so you never get caught short before your next refill.
Travel beyond South Korea
If your South Korea trip is part of a wider journey, Yesim covers many other destinations from the same app — manage everything in one place.
Flexible up to 30 days
Yesim South Korea plans run up to 30 days from first use. Buy in advance so you're ready the moment you land.
Which Yesim plan should you pick?
For a short city break of 3–6 days, the cheapest plan at $3.10will cover Maps, WhatsApp and casual browsing. If you’re spending one to two weeks travelling around South Korea, step up to a mid-tier plan — usually the strongest value on a per-GB basis in Yesim’s South Korea lineup.
If you plan to work remotely, stream video daily, or use your phone as a hotspot, lean towards a larger bundle. The unlimited plans cost a premium but make sense for heavy users who don’t want to track usage.
One thing to note: Yesim South Koreaplans are data-only. You won’t get a local number, but your existing SIM handles calls and texts as normal — messages, WhatsApp and FaceTime all work over data.
