South Korea eSIM data plans

South Korea eSIM prices at a glance

SoloSim sells 33 prepaid eSIM plans for South Korea, priced from $0.70 to $37.50 and valid for between 1 and 30 days. The smallest is 100 MB for 7 days at $0.70; the largest is 50 GB for 30 days at $37.50. The best value per gigabyte is the 50 GB for 30 days plan, which works out at $0.75 per GB. 18 of the plans are daily allowances — the data resets every 24 hours instead of being a single balance for the trip.

Network and speed in South Korea

Every South Korea plan connects over 3G/4G/5G networks. 18 of the plans slow down rather than stop when their allowance is used up: they drop to 512 Kbps, 1 Mbps or 384 Kbps for the rest of the validity period, so maps and messaging keep working. Traffic exits to the internet through SG, which is the location websites and apps will see you connecting from.

Which South Korea plan for your trip?

• A long weekend (up to 3 days): 100 MB for 7 days at $0.70.
• Two weeks: 3 GB for 15 days at $3.80.
• A month: 3 GB for 30 days at $4.00.

Plans are prepaid and data-only, so if you run low you top up from the app rather than paying overage.

How it works

1. Pick a plan and pay online — no account or physical SIM needed.
2. Scan the QR code we send you to install the eSIM on your phone. Check your phone is eSIM compatible.
3. Turn on data roaming for the eSIM when you land and you're online.

South Korea eSIM — frequently asked questions

How much does a South Korea eSIM cost?

South Korea eSIM plans on SoloSim start at $0.70 and go up to $37.50 for the largest plan. Prices are in USD and include everything — there is no activation fee and no roaming charge on top.

Does the South Korea eSIM support 5G?

Yes. All plans for South Korea connect over 3G/4G/5G networks, and your phone will use the fastest one available where you are.

How long is a South Korea eSIM valid?

The validity period starts when the eSIM first connects to a network in South Korea, not when you buy it, so you can install it at home before you fly. The longest South Korea plan currently lasts 30 days.

What happens when I use all the data on my South Korea eSIM?

Plans with a fair-use policy slow to 512 Kbps, 1 Mbps or 384 Kbps for the remainder of the validity period instead of cutting off. Top up from My eSIMs in two taps — added data shares the current expiry date. With low data alerts on, we warn you at 80% and 95%.

Can I keep my own number while using a South Korea eSIM?

Yes. The eSIM carries data only; calls and texts keep working on your home SIM. Just make sure data roaming is off on the home line.

How do I install the South Korea eSIM?

After purchase you get a QR code. On Wi-Fi, scan it from another device (or use the one-tap link on the same phone), then enable the new data line in Settings.
