Local know-how
What to know before you land in South Korea
Coverage and networks
Millimeter-wave 5G is not one of your options here. Korea's science and ICT ministry canceled KT's and LG U+'s 28 GHz licenses in December 2022 and SK Telecom's ended the year after, so every 5G phone rides 3.5 GHz mid-band on one of those three carriers. It is quick anyway: in the 2025 national quality evaluation KT posted the fastest nationwide 5G download for the first time, a shade over 1 Gbps, while SK Telecom rated best at holding a usable speed. The three sit close together. What stays wide is the metropolitan versus rural gap. When the ministry rechecked 87 flagged weak spots in August 2026, 79 had improved and the eight still failing were all subway stretches.
Landing and activation
Long-haul lands at Incheon; Gimpo takes short hops, Gimhae serves Busan, Jeju has its own. File the e-Arrival Card before you fly. The window opens three days ahead of arrival in Korean time, not after you land, and you skip it only on a K-ETA or a Korean residence card. Airport Wi-Fi is free, but Korean public and carrier hotspots commonly verify you by texting a code to a Korean number, which a data-only profile cannot receive, so finish the paperwork at home. At Incheon Terminal 1 the three carriers staff roaming counters in departures near Gates 3 and 4 and in arrivals near Gates A and F, mostly 06:00 to 22:00, one near Gate F around the clock. The counter wants your passport before it issues anything.
What connectivity costs here
The number you can actually check is roaming: Telstra bills A$10 a day for 2 GB in Korea, and most home carriers file Korea in their far zone, so two weeks of it outruns anything local. Carrier counters at Incheon sell tourist SIMs by duration rather than by gigabyte, and the counter tier is the expensive way to buy days; tiers move, so read the board instead of trusting a figure you saw online. For scale, Koreans pay around 30,000 won, roughly $20, for a headline unlimited plan that runs full speed only to a small allowance and then throttles. Free Wi-Fi sits in every cafe and hotel, which is what makes the pocket router desks in Incheon arrivals hard to justify.
Which plan fits your trip
Korea only cleared Google's high-precision map data for export in February 2026, under security conditions, and Google was still staffing up its Korean maps team in August, so do not arrive relying on turn-by-turn in Google Maps. Naver Map carries an English map and English navigation; KakaoMap is the other default. Neither offers offline maps, so every walk between subway exits is a live-data job. Papago does translate offline once you download a language, which takes that load off the plan. Install Kakao T, or Kakao Mobility's English-language k.ride, and register a card while you still have home connectivity. Budget 5 GB for five to seven transit days across Seoul and Busan; a Jeju rental car or daily uploads push that to 10 GB.

Going to more than just South Korea?
A regional bundle covers South Korea and 17+ other countries on a single eSIM, often cheaper than buying separate single-country plans for a multi-stop trip.
Frequently asked about South Korea eSIMs
Yes. The GetSim eSIM installs as a second profile on your phone. Your home SIM and number stay active for calls and SMS. Set the GetSim eSIM as the default for cellular data only.
Plans run on tier-1 mobile networks in South Korea. The exact carrier depends on the plan; you'll see the network name on each plan card before you pay.
Typical activation is 1–3 minutes after switching the eSIM on. Many travelers install the eSIM at home over Wi-Fi and toggle it on the moment the plane lands.
GetSim eSIMs are data-only. For voice and SMS, use apps like WhatsApp, FaceTime, Signal or Telegram. They all work seamlessly over the eSIM data. If you need a real phone number for verifications, pair the eSIM with a GetSim virtual number from the same wallet.
Top up the eSIM directly from your dashboard or the GetSim app, no need to install a new profile. Top-ups are billed per-GB at the same rate as the original plan.
