Questions
Which networks does the South Korea eSIM use?
The South Korea eSIM connects to SK. It lists 5G; a 5G phone uses it where the network has it, 4G elsewhere.
How much data do I need for a week in South Korea?
About 3.5 GB if you use maps, messaging, socials and photos (our estimate: 0.5 GB a day). Our pick for 7 days is 5 GB · 30 days for $8.99.
Is it worth getting an eSIM for South Korea?
For most trips, yes. The lowest daily cost is $0.17 a day (3 GB · 30 days for $4.99). You install it before you fly, your home SIM stays on for calls and texts, and nothing renews. If your home plan charges for roaming, compare its daily rate with this.
Is there an unlimited data plan for South Korea?
Yes, from $9.99 for 3 days. Lower speed rate of 1 Mbps after 3 GB usage per day.
Do South Korea plans include a phone number?
No, they're data only. Your home SIM stays on for calls and texts, and messaging apps and internet calls work over the eSIM data.
Can I add data to my South Korea eSIM?
Yes. When you run low, top up from My eSIMs on this site or in the app; the eSIM stays installed.
When does the plan start?
When your phone first connects to a network in the destination, not when you buy. Install it at home on Wi-Fi; the days start counting on arrival.
