South Korea moves fast, from the palaces and neon of Seoul and the street food of Myeongdong to the beaches of Busan, the volcanic island of Jeju and the tense line of the DMZ. An eSIM keeps you online in a country practically built for connectivity — think K-pop, cafés, and the world's quickest mobile internet. With transit cards, translation and endless food maps all on data, staying connected is half the fun of a Korea trip.

Your phone connects automatically to the country's ultra-fast networks wherever you go, from the subways and long tunnels to Jeju and the mountains.

How much data for South Korea?
Maps & messaging
≈ 0.5 GB / day
+ Social media & photos
≈ 1 GB / day
+ Streaming & video calls
≈ 2–3 GB / day
Korea invites heavy data use — everything is an app. A few days in Seoul run on 4–6 GB, while a week adding Busan and Jeju with constant maps, translation and reels is better with 10–15 GB. Navigation, KakaoTalk, café-hopping photos and video calls are the main uses — take the higher end if you post throughout the day.
eSIM South Korea — Frequently asked questions
Yes, superbly. Korea's networks cover the entire subway, including deep tunnels, and the KTX high-speed line, so you can navigate, stream and translate without interruption between stops.
No. There's no ID requirement and no local registration — you scan the QR code, enable the eSIM on arrival and you're online, while your T-money transit card is bought separately at any convenience store.
An eSIM is a digital SIM card built into your phone. No physical card needed — just scan a QR code from your email or My eSIMs section to activate your plan instantly.
Compatibility
iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+ and most phones from 2018 onwards support eSIM. Go to Settings → About — if you see an EID number, you are compatible.
Yes — our plans are data only. Your regular SIM stays active for calls and SMS. You stay reachable on your usual number while your eSIM handles data abroad.
Most phones store up to 5-10 eSIM profiles but only one can be active for data at a time. You can switch between them anytime in your phone settings.
Data & Plans
Your plan starts at your first network connection at destination — not at purchase. Install at home, travel freely, your days only count when you actually use it abroad.
Yes — all our plans include hotspot at no extra cost. Share your connection with your laptop or tablet directly from your phone settings.
Single country plans work in one country only. If you visit multiple destinations, check our regional plans — Europe covers 33 countries, Asia 20, Worldwide 118 and more.
Yes — you can top up your plan at any time from My eSIMs. Important: top up before your plan expires, as top-ups cannot be applied to expired plans.
Installation
After purchase, find your QR code in your confirmation email or in My eSIMs. Go to Settings → Mobile Data → Add eSIM → Scan QR code. You need WiFi for installation.
Install it before you leave — it only needs WiFi. Switch it as your data line only when you arrive at your destination. Your plan starts automatically at first local network connection.
Yes — enable data roaming for your eSIM Agora line in Settings → Mobile Data → select your eSIM → Data Roaming on. Without this, your eSIM cannot connect to local networks abroad.
Make sure you are on WiFi. Each QR code works only once — if already scanned, go to My eSIMs to reinstall. Still not working? Contact us at support@esimagora.com and we will fix it quickly.
Payment & Support
We accept Visa, Mastercard, American Express and Google Pay. All payments are processed securely by Stripe.
Completely — Stripe handles all payments and is PCI DSS Level 1 certified. We never store your card details. Every transaction is SSL encrypted.
First check: is data roaming enabled? Is the right eSIM selected for data? If yes and still not working, email us at support@esimagora.com — we respond within 24 hours.
Unlimited Data
You get a set amount of high-speed data each day (e.g. 1 GB/day). Once you've used that daily quota, you keep browsing at reduced speed (1 Mbps) — never cut off. Every day, your high speed starts fresh.
Fixed (e.g. 5 GB/30 days): one total amount of data to manage over the whole period, at full speed until it runs out. Unlimited: a daily quota that renews, so you're never completely out. Ideal if you'd rather not track your usage, or if you're staying a while.
You switch to 1 Mbps (enough for WhatsApp, maps and browsing, but not HD streaming). It goes back to full speed the next day.
About every 24 h after your first connection (it can vary by carrier — not necessarily at midnight).
Yes — via "Add days" while it's still active (not expired). It adds days, not extra daily data.
Unlimited if: long stay, unpredictable usage, you want peace of mind. Fixed if: short stay, light or precise usage, you want the best value.
