Can I use it the moment I reach Asia?

Yes. Install it before you leave and it joins a local network on its own as soon as you arrive in Asia. Just make sure roaming is switched on for the eSIM line.

Can I extend my Asia eSIM plan?

Yes. If you run low on data, you can buy and install an extra plan at any time. Your existing eSIM profile stays as it is.

How fast is an eSIM in Asia?

eSIM plans for Asia use local 4G/LTE networks. Actual speed depends on local network conditions, but is usually around 10–50 Mbps.

Can I still use my Korean number when I'm on an eSIM in Asia?

Yes. The eSIM works as an extra line for data only. Your Korean SIM keeps its number, so KakaoTalk messages and calls to your usual number still reach you.

Does eSIM work in Asia?

Asia supports eSIM, and plans start from ₩7,519. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Asia?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Can I use tethering (hotspot) in Asia?

Yes. In Asia you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Asia. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

How many GB of data do I need for a trip to Asia?

For mostly maps and messaging, we recommend about 1 GB a day; to use plenty of social media and photo uploads, about 2 GB a day. If you stream a lot of video or tether a lot, an unlimited plan is better. You can always buy more if you run short, so it is fine to choose a little extra at first.

Does my smartphone support eSIM?

You can use it if your phone supports eSIM. iPhone supports it from the XS and XR onwards; Galaxy phones sold in Korea from the S23, Z Flip4 and Z Fold4 onwards. Dial *#06# in the phone app: if an EID number appears, your phone supports eSIM. If it is SIM-locked, it needs to be unlocked.
