Unlimited eSIM South Korea: Real specs before you buy
"Unlimited" means different things across eSIM providers. The table below shows exact details from the plan you’ll receive — including your high-speed data allowance, post-threshold speeds, and carrier — so you know exactly what you’re buying.
What can I still do in South Korea after using up my 1GB high-speed data allowance?
1GB high-speed data ≈ 3.3 hours of 360p video or 0.9 hours of 720p HD video (estimated using YouTube’s recommended bitrates). Once exhausted, speeds will be reduced to 384 Kbps – 1 Mbps (depending on the number of days you select) until your daily allowance resets:
- Message WhatsApp, iMessage, Messenger
- Email and Google Maps navigation
- Voice calls via apps
- Watch videos and scroll Reels/TikTok (very slow downloads)
- Video calls
- HD video streaming, large file downloads, and hotspot sharing with a laptop
The list above shows the lowest available rate (384 Kbps) to avoid surprises.

Using mobile data in South Korea: local tips
- Use a Korean map app. Google Maps has long lacked full walking and driving directions in South Korea. Install Naver Map or KakaoMap before you arrive — they are what locals use.
- Naver Map works in English. Naver Map has an English interface with live transit departure times and alerts telling you when to get on and off — live updates need an internet connection.
- Papago for menus and signs. Naver’s Papago translates text in photos and handles two-way voice conversations. Text translation also works offline if the signal drops.
- Taxis without a Korean number. Kakao Mobility’s k.ride app is built for visitors: sign up with Google, Apple or email and pay with a card issued abroad.
- Expect dips on some rail sections. Korean 5G is very fast overall, but government tests found weaker 5G on subway lines and some KTX/SRT sections, so connections may slow down on those routes.
- Help over data. Korea’s official 1330 Travel Helpline can be reached by chat through KakaoTalk, Line, Facebook or its own messenger — no Korean phone number needed.

FAQs about South Korea eSIM
Everything you need to stay connected on your trip.
Unlimited data: your connection will never be cut off. However, high-speed data is limited to 1GB per day; once exhausted, speeds will be reduced until your daily allowance resets. Post-threshold speed in South Korea: 384 Kbps – 1 Mbps (depending on the number of days you select).
Connects via SK Telecom, LG U+, KT. Your device automatically selects the strongest available local carrier — no manual selection needed. 5G is available where the local carrier has deployed it; elsewhere, 4G applies.
At 384 Kbps these still work: Message WhatsApp, iMessage, Messenger, Email and Google Maps navigation, Voice calls via apps. Not recommended: Watch videos and scroll Reels/TikTok (very slow downloads), Video calls, HD video streaming, large file downloads, and hotspot sharing with a laptop.
Unlimited (1GB/day high-speed data) starting at 19,037 ₫/day is enough for maps, messaging, and social media. Unlimited Plus (3GB/day) starting at 28,562 ₫/day is better if you frequently make video calls, post stories/videos, or share a hotspot with travel companions. Choose Premium starting at 77,038 ₫/day if you need all-day high-speed data without limits — ideal for remote work or sharing a hotspot with your laptop.
Yes. Note that hotspot usage counts toward your plan’s high-speed data allowance — a single laptop can quickly consume 1GB, and carriers may throttle speeds when hotspotting. For group sharing, we recommend Unlimited Plus or Premium.
The number of days starts when your eSIM first connects to mobile data at your destination — not from the purchase date. We recommend installing your eSIM before departure and only enabling it upon landing. Some plans auto-activate 30 days after purchase if unused, so buy close to your travel date.
Most iPhone XS+, Galaxy S20+, and Pixel 3+ models support eSIM. Your device must be unlocked.
No. This is a data-only plan; you’ll make calls and send messages via WhatsApp, iMessage, Messenger.
100% refund if the eSIM hasn’t been activated or if there’s a technical issue caused by us that we cannot resolve.
