Can I use an eSIM in South Korea?
Yes. LTE.app eSIMs work in South Korea on compatible eSIM devices including most iPhones (XS and later) and many Android phones released after 2018. Check our device compatibility page for the full list.
When does my South Korea eSIM activate?
Your eSIM activates when you first connect to a local network in South Korea. You can install it at home over Wi-Fi before you travel — the data countdown only starts when your phone connects to a South Korea carrier after you arrive.
Can I use mobile hotspot (tethering) in South Korea?
Yes. Most LTE.app plans for South Korea support mobile hotspot, so you can share your data connection with a laptop or travel companion. Hotspot availability is shown on each plan card.
Can I use my regular SIM and the South Korea eSIM at the same time?
Yes, if your phone supports dual SIM. You can keep your home SIM active for calls and texts while the South Korea eSIM handles data. Most modern iPhones (XS and later) and Android flagships support this — check your phone's specs to confirm.
