FAQs about the Seoul eSIM
Will my eSIM work the moment I land in Seoul?
Install your Teraroma South Korea eSIM at home before you fly. The plan starts when your phone first connects to a local network in South Korea, as long as the eSIM line and data roaming are switched on.
Which networks does the Seoul eSIM use?
Our current South Korea plans connect to SKTelecom, LG Uplus. The network your phone picks depends on the plan and local signal.
Do I need a separate eSIM for other cities in South Korea?
No. South Korea plans are country-wide, so the same eSIM works in Seoul and anywhere else the local networks cover.
Can I keep my home number while using a Seoul eSIM?
Yes. Teraroma eSIMs are data-only and run alongside your home SIM, so calls and SMS to your usual number keep arriving.
What if I need more data while I'm in Seoul?
Top up your existing eSIM from the Teraroma top-up page. You don't need to install a new eSIM mid-trip.
