Share with your laptop
Hotspot is allowed on the plan selected above, so a second device can use the same data in a cafe or a hotel room.

South Korea travel data guide
A South Korea eSIM from RoamZivo is a prepaid data plan for South Korea that you install before you fly. Plans in South Korea run on SKTelecom and LG Uplus, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 20 plans to choose from. Data sizes run from 1 GB to 50 GB, validity from 1 to 30 days, and prices start at $1.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on some of the fixed data plans and go onto the same eSIM.
Visiting more than one country? The Japan & South Korea eSIM covers South Korea and 1 other country on one plan, from $2.99. The Asia (14 countries) eSIM covers South Korea and 13 other countries on one plan, from $2.99. The Asia Pacific eSIM covers South Korea and 19 other countries on one plan, from $10.99. The Global eSIM covers South Korea and 126 other countries on one plan, from $18.99.
Your days start the first time the eSIM connects in South Korea, not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in South Korea from RoamZivo arrives as a QR code by email, with a copy kept in your account.
South Korea FAQ
Does the eSIM work everywhere in South Korea?
It connects wherever SKTelecom and LG Uplus have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in South Korea, not at purchase. The plan selected above (2 GB) runs for 15 days from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in South Korea?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
Is unlimited data worth it for South Korea?
For most visitors to South Korea, yes. Maps, translation and transit lookups add up over a full day. The unlimited plans give 1 GB or 3 GB per day at full speed and then continue at up to 1 Mbps.
Which networks does the South Korea eSIM use?
The South Korea eSIM uses SKTelecom and LG Uplus, both listed with 5G. You do not select one at purchase. The phone connects to whichever of the two is available where you are.
Can I receive SMS verification codes in South Korea with the eSIM?
Not on the eSIM, because it has no phone number. Codes sent to your home number arrive on your home SIM if it is active in South Korea. Codes that require a Korean number cannot be received with this plan.
Should I install the South Korea eSIM at home or at the airport?
Install it at home. You need WiFi to download it, and doing it before you travel means your data works once you land in South Korea. The plan does not start until the eSIM first connects there.
Does my home SIM need to come out of the phone?
No. Your home SIM stays in place and the South Korea eSIM is added as a second line. In settings, choose the eSIM for mobile data and turn data roaming off for the home SIM.
Can I top up my South Korea eSIM?
Some South Korea plans support top up and some do not. This is shown in the plan details. If yours has no top up, buying a new plan is the way to get more data.
Can I share data with friends in South Korea?
Yes, hotspot is allowed on all South Korea plans. Friends connect to your phone over WiFi and use your allowance. On unlimited plans the shared use counts toward your daily full speed amount.
How do I top up if I run low?
The plan selected above does not offer top ups. Buy a new plan from this page instead and install it as a second eSIM.
