Questions travellers often ask
Does eSIM work on my phone model?
Most recent smartphones support eSIM. It’s worth checking your phone’s settings menu for an eSIM option to confirm compatibility ahead of your trip.
Can I make calls and send texts with an eSIM?
Most eSIM plans focus on data, though some offer calling and texting add-ons. Many travellers pair data-only eSIMs with messaging apps for calls instead.
Should I set it up before I arrive?
Yes, it’s best to install your eSIM profile before departure so it’s ready to activate the second you land in South Korea, without needing airport Wi-Fi first.
