5GB for a week. $10.01.
A fixed amount of data, said plainly. Use it up and it slows to 128 kbps; no surprise bill. Unlimited is in the table if you stream.
Install takes two minutes. Naver Map needs data to work at all.

열두달
Deep cold and empty palaces. Ski season in Gangwon.
The coldest weeks end; Seollal shuts the country for three days.
Grey turns green. Cherry blossom reaches Jeju at the end of the month.
Blossom sweeps north: Jinhae, then Yeouido, then Seoul.
The best month. Warm, dry, and everything is open.
Green and humid; the rains build toward the end.
Monsoon. Museums, cafes and the odd perfect blue day.
Hot and loud. Beaches, festivals, and air conditioning.
Chuseok empties Seoul and fills every road out of it.
Autumn starts on Seoraksan's ridges. Ideal walking weather.
Peak danpung in Seoul, then Busan. Our favourite month.
First snow, illuminations, and a quiet run-up to New Year.
비자
Most EU, UK, Australian, US and Canadian passports enter visa-free for 90 days, but you must apply for **K-ETA** online before you fly unless your nationality is on the current exemption list. Checked Sep 8, 2026; rules change, confirm on the official K-ETA site.
Fill in the arrival card and customs declaration through Q-CODE or on paper; Q-CODE is faster at Incheon.
Your passport only needs to stay valid for the length of the stay.

Google Maps cannot route you in Korea. Install Naver Map or KakaoMap before you fly; both need data.
One T-money card covers subway, bus and taxis, and tops up at any convenience store.
Korea is nearly cashless, but small eateries and markets still want notes. Airport ATMs take foreign cards.
Passport at the till gets VAT back on purchases over ₩15,000 in participating shops.
Public Wi-Fi is everywhere and mostly locked. That is the whole reason this page exists.

If an EID appears, your phone takes an eSIM.
No EID? Don't buy this. The counters in Incheon arrivals sell physical SIMs.

Fixed plans keep working at 128 kbps, enough for KakaoTalk and a map, not for video. No extra charge. Need more? Unlimited plans stay at full speed.
LG U+, on 4G and 5G.
Not at purchase. Each plan says at checkout whether its days begin when you install it or when it first connects in Korea.
It depends on the plan, and checkout shows it before you pay. Hotspot uses the same data.

Prices are the Fizen eSIM catalog, checked October 6, 2026. The price at checkout is the one that counts.
Strong signal in the cities, on the KTX line and across the subway. Deep valleys in Gangwon can drop out.
Japan, Thailand, UAE, USA, Europe, China and 80+ more, from the same team at fizen.io.
One short email a week while you travel: the queue worth joining, the last subway, the hill you should climb at sunrise.
