Coverage and networks

Your eSIM connects to a partner network in South Korea and switches if the signal is better on another one. The networks for each plan are confirmed at checkout.

South Korea’s mobile networks are fast and everywhere, and daily life assumes you use them – taxi and delivery apps, translation, and maps for subway systems with hundreds of stations.

One thing surprises visitors: Google Maps shows public transport in Korea but does not give driving or walking directions there. Most travellers install a local map app such as Naver Map, which has an English interface and needs mobile data to work well.

    The 30 days start from the first connection to a partner network.

Check your phone first

Your phone must support eSIM and be carrier-unlocked. If it was bought from a mobile network on contract, ask them to unlock it before you travel.

  • Dial *#06#. If you see an EID number, your phone supports eSIM.
  • Most iPhones from XR and XS onwards, Google Pixel 3 onwards and Samsung Galaxy S20 onwards support eSIM.

We check it against the list of eSIM phones. Nothing is saved.

South Korea eSIM questions

Why does Google Maps not give directions in South Korea?

Korean rules restrict exporting detailed map data, so Google Maps offers public transport routes but no driving or walking directions. Local apps such as Naver Map fill the gap.

Will it work on the KTX and the Seoul subway?

Korean networks cover the KTX high-speed lines and the subway, including stations and tunnels, so you can stay online almost everywhere you travel.

Can I use one eSIM for Japan and South Korea?

A South Korea plan works only in South Korea. For a trip to both, an Asia regional plan covers Japan and South Korea on one eSIM – the full country list is on the plan before you pay.

Can I buy the plan now and travel next month?

Yes. The plan starts when the eSIM first connects in South Korea. Install it within 180 days of buying.
