Which carriers will I be on in Puerto Rico?

It runs on local networks like Claro and Liberty, over 4G/LTE.

Can I keep using my Korean number?

Yes. The eSIM sits alongside your normal SIM as a data-only line; calls and texts still use your Korean SIM and number.

How do I get the eSIM working?

After purchase, a QR code arrives by email. Open your phone's settings and scan it there; installing before departure is recommended, and it works on arrival.

Is an eSIM worth it, or will roaming do?

Roaming abroad on a Korean carrier is expensive and not always supported. A flat-rate eSIM gives you data without the worry.

Does eSIM work in Puerto Rico?

Puerto Rico supports eSIM, and plans start from ₩2,999. 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 Puerto Rico 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 Puerto Rico?

Yes. In Puerto Rico 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 Puerto Rico. 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 Puerto Rico?

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.
