Why use an eSIM?
An eSIM for South Korea keeps navigation, ride-hailing and translation apps running from the moment you land, connecting to national networks without roaming surcharges. A local South Korea data plan installs in minutes and you pay in stablecoins from your own wallet, because AgentRoam does not custody user funds. Your device must be eSIM-compatible and carrier-unlocked, and delivery usually happens after payment confirmation.
No SIM swapping
Install a data profile digitally — no plastic SIM, no airport kiosk. Set it up before you fly and switch it on when you land.
Pay from your wallet
Check out in USDC, USDT or crypto straight from self-custody. AgentRoam does not custody user funds, and guest checkout is available where supported.
Delivered by email
Your eSIM arrives as a QR code by email. Delivery usually happens after payment confirmation, and your order page shows live status.

How do I install an eSIM for South Korea?
After your payment confirms, we email a QR code — open your phone's mobile-data settings, scan it, and the South Korea plan is added. Most plans activate when they connect to a network in South Korea, so you can set it up before departure.

Does an eSIM for South Korea cover cities and rural areas?
South Korea data plans use national networks with solid coverage in cities and along main routes; remote and rural signal varies. Confirm your device is eSIM-compatible and carrier-unlocked before you buy.
How much data should I buy for South Korea?
It depends on maps, streaming and hotspot use. Compare the plan sizes and prices above and buy more data if you run low rather than overbuying upfront.
