Which carriers does the eSIM connect to in American Samoa?

It runs on local carriers including Bluesky Communications and ASTCA, on 4G/LTE.

Can I keep using my Korean number?

Yes. This eSIM sits alongside your current SIM as a separate, data-only plan. Your Korean SIM and number stay as they are for calls and texts.

How do I get the eSIM working?

Once your order goes through, a QR code arrives in your inbox. Open your phone's settings and scan it; setting it up before you fly is the best approach. It works as soon as you land.

Is an eSIM worth it, or will roaming do?

Roaming abroad with a Korean carrier is expensive, and sometimes it is not supported. An eSIM gives you data for one fixed price, so there is nothing to worry about.

Does eSIM work in American Samoa?

American Samoa supports eSIM, and plans start from ₩11,587. 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.

Can I add to or extend my American Samoa eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in American Samoa?

Yes. In American Samoa 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 American Samoa. 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 American Samoa?

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.
