South Korea eSIM questions
Which network will I use in South Korea?
Dayo connects to SK Telecom, 5G. If that network is busy, your phone can switch to a partner network automatically.
Will I have data as soon as I land at Incheon (ICN)?
Yes. Install Dayo at home before you fly, then turn it on when you land. Your plan's days start the first time it connects in South Korea, so you can book a Kakao T from the arrivals hall.
Does it work outside Seoul?
Yes. Your plan works anywhere the network covers in South Korea, including Busan, Jeju.
Visiting more than one country?
A regional plan may be better: Asia 9 covers South Korea and its neighbours on one eSIM.
