How much does this plan cost?
22 prepaid eSIM plans on this page, from $8.00 USD — a one-off purchase with no contract and no subscription. Options on the same page differ by coverage or by speed, never by validity.
Which networks does a Lumo eSIM use in South Korea?
By option: South Korea — SKTelecom · LG Uplus 5G; Japan + South Korea — KDDI/au · SoftBank · SKTelecom · LG Uplus 5G. Coverage is South Korea, or Japan + South Korea — where the data service works, and the operator names are the ones the network reports for each plan.
What does unlimited mean on this plan?
Each option includes a full-speed allowance of 1–10 GB per day. Once it is used the connection continues at a reduced speed (384–1024 kbps depending on plan) until the next day, then resets. There is no hard cut-off and no overage charge.
Can I make calls or send SMS?
No. Lumo plans for South Korea are data-only — they provide mobile internet with no calls, SMS or phone number. Keep your primary SIM active if you need voice and text.
Will my phone work with a Lumo eSIM?
Most phones released from 2018 onwards support eSIM, including iPhone XS and later, Google Pixel 3 and later, and many Samsung Galaxy models. Check Settings > Cellular (or Mobile Data) for an eSIM or Add Cellular Plan option, and make sure the phone is carrier-unlocked.
When do the 7 days start?
When the eSIM is activated, which our terms count as the moment the profile is installed and provisioned on your device, or the moment it first connects to a partner network — whichever happens first. Install it close to your trip rather than the day you buy it, and turn on data roaming for the Lumo line once you arrive in South Korea. That same moment is when the plan stops being refundable, so installing is not a step you can undo.
Can I share this plan over a hotspot?
Yes. Every option on this page is recorded as supporting hotspot and tethering, so a laptop or a second phone can use the connection. Shared traffic comes out of the same allowance.
How quickly can I get connected in South Korea?
No account or registration is required to buy. Your plan arrives instantly by email and activation takes about 30 seconds. Turn on data roaming for the Lumo line once you arrive in South Korea to start using mobile internet.
Can I get a refund if I do not use my plan?
Unused eSIMs can be cancelled and refunded in full within seven days, as long as they have not been activated. Once an eSIM has been activated it is no longer refundable.
