Coverage during your trip
Connectivity is generally strong in major cities and on busy transport corridors. Mountain hiking routes, underground spaces, ferries, and less-populated parts of Jeju can still produce temporary gaps depending on the local network.
Choosing and preparing your plan
Navigation platforms and translation tools may differ from those used at home, so install and test the apps you need before departure. Choose more data for video, cloud photo backup, or hotspot use and keep essential reservations offline.
South Korea eSIM questions
Why isn't my eSIM working in South Korea?
Confirm that the eSIM is selected for mobile data, data roaming is enabled, and airplane mode is off. Restart your phone after arrival; if it still does not connect, check the APN instructions supplied with the plan.
How do I check my South Korea eSIM data balance?
Sign in to Flowsus, open My eSIMs, and select the active eSIM to see its remaining data and latest usage update.
Can I keep my WhatsApp number while using an eSIM?
Yes. Keep your primary SIM active for your phone number and select the Flowsus eSIM for mobile data. WhatsApp keeps its registered number unless you choose to change it inside the app.
Can one eSIM profile be used on multiple phones?
Usually not. An issued eSIM profile is intended for one device. Do not delete an installed eSIM unless Flowsus support instructs you to do so. Contact support before changing phones or attempting to reinstall it.
