About South Korea eSIM

VoyaSIM's South Korea eSIM connects to SK Telecom, KT, or LG U+ (varies by plan), with 4G/LTE and 5G nationwide. Coverage spans Seoul, Busan, Incheon, and Jeju Island.

Good to know: South Korea has the fastest mobile networks in the world — even entry-level plans regularly deliver over 100 Mbps in metropolitan areas. 5G is the default.

How it works: Choose a plan above, complete checkout, and receive your QR code by email. On iPhone, go to Settings → Cellular → Add Cellular Plan and scan. On Android, go to Settings → Network & Internet → Mobile Network → Add Carrier.
