Travel data for South Korea
eSIM for South Korea: prepaid travel data without roaming charges
Seoul runs on some of the fastest mobile networks in the world. A travel eSIM puts you on one of them the minute you land at Incheon, with no rental counter and no deposit.
- One fixed price
- You pay once, up front. Nothing renews by itself and there is no per megabyte charge afterwards.
- Local network speed
- Your phone attaches to a major Korean network with 5G in Seoul, Busan and along the KTX routes.
- Keep your own number
- The travel plan runs beside your normal line, so calls, texts and two factor codes keep arriving.

Travel eSIM versus roaming from your own carrier
| What matters | Netcom Travel eSIM | roaming from your own carrier |
|---|---|---|
| Price for a two week trip | One upfront amount, shown before you pay | Daily pass fees that add up per line |
| Setup | QR code by email, installed before departure | Add on to activate, per line, per country |
| Speed | Local 5G where available in South Korea | Often throttled after a small allowance |
| Your own number | Stays active alongside the travel line | Stays active, at roaming rates |
| Running out | Top up from your order page in a minute | Another pass or an overage rate |
Frequently asked questions
Will an eSIM work on my phone in South Korea?
Yes on any eSIM capable phone that is carrier unlocked. That covers iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S and Z models. You can check your exact model on our device page.
Do I keep my own phone number?
Yes. The travel eSIM is a second line for data only. Your normal line stays active for calls and texts, so bank codes and iMessage keep working.
When should I install it?
Install at home over Wi-Fi, ideally the day before you fly. Validity starts when the eSIM first connects to a network in South Korea, not when you buy it.
Country plan or Asia regional plan?
Korea and Japan in one trip is a common combination. The Asia regional plan covers both, which saves installing a second eSIM in Tokyo.
Is this cheaper than a local SIM card?
Pocket Wi-Fi rental means queueing twice, once to collect and once to return, and it is one more device to charge. With an eSIM you buy in advance, in euro, and you are online before you leave the plane.
What if I run out of data?
You top up from your order page in about a minute. The same eSIM keeps working, so there is nothing to reinstall.
