Coverage & network in South Korea
South Korea is straightforward for eSIM travellers — the profile attaches to whichever partner network is strongest where you’re standing, and the plan runs on the phone already in your pocket.
As a rule of thumb: maps and messaging burn 100–200 MB a day, social media roughly 500 MB an hour, and a video call about 1 GB an hour. A light week fits in a small plan; remote work needs a big one.
5G is available in South Korea on plans marked 5G, wherever your handset and the local network both support it; elsewhere you’ll be on 4G/LTE, which is what most of the country actually runs on. Tethering is allowed on every South Korea plan, so a laptop or a travelling companion can share the connection.
Crossing borders on the same trip? The Asia plan covers much of the region on one profile. Otherwise there are separate plans for Japan, Kazakhstan and Kyrgyzstan.
How to install it
- 1
Buy in a minute
Pick a South Korea plan and pay. Your QR code arrives by email within minutes — no account, no shipping.
- 2
Install on Wi-Fi
Scan the code before you fly. The profile sits alongside your normal SIM and stays switched off until you need it.
- 3
Land connected
Turn on data roaming for the TravelNet line when you arrive. The plan starts counting down on that first connection, not at checkout.
Will my phone work?
You need an eSIM-capable, carrier-unlocked phone: an iPhone XS or newer, a Pixel 3 or
newer, or a recent Samsung Galaxy S, Z or A-series flagship. Dial *#06# — if
an EID number is listed alongside the IMEI, the phone has an eSIM.

South Korea eSIM questions
Which network does the South Korea eSIM use?
We don't publish a single operator name for South Korea, because the profile can attach to more than one partner network and picks whichever is strongest where you are. In practice that means you get the best available signal rather than being locked to one operator's weak spots.
Will I get 5G in South Korea?
On plans marked 5G, yes — where the network has deployed it and your phone supports it. Outside those areas the eSIM falls back to 4G/LTE automatically; you won't need to change any setting.
How much data do I actually need for South Korea?
Count on 100–200 MB a day if you're mostly using maps and messaging, and 1 GB an hour once video is involved. Pick the plan one size up from your estimate — running out abroad costs more hassle than the size difference.
When does my South Korea plan start counting down?
When the eSIM first connects to a network in South Korea, not when you buy it. Install it at home a day or two before you fly — the validity period on the plan you choose runs from arrival, not from checkout.
Can I use my South Korea eSIM as a hotspot?
Yes. Tethering is enabled on every South Korea plan, so you can share the connection with a laptop, a tablet or someone travelling with you. Hotspot data comes out of the same allowance.
Can I keep my own phone number while I'm in South Korea?
Yes — that's the main reason to use an eSIM rather than a local SIM. Your home line stays active for calls, SMS and two-factor codes; the South Korea eSIM sits alongside it as a data-only line. Leave data roaming off for your home line to avoid a surprise bill.
Do I need to register or show a passport to use a South Korea eSIM?
No. The plan roams on partner networks, so there's no local SIM registration, no ID upload and no shop visit. You buy it, scan the QR code, and it works on arrival.
What happens if I run out of data in South Korea?
You can buy another South Korea plan from the same page and install it the same way. Plans marked as top-up capable can also be extended without a new QR code.
I'm also visiting Japan and Kazakhstan — do I need separate eSIMs?
Not necessarily. The Asia plan covers much of the region including South Korea on a single profile. If South Korea is the bulk of the trip, a country plan is usually the better buy; if you're crossing several borders, the regional plan wins.
Will my phone work with a South Korea eSIM?
If it's an iPhone XS or newer, a Pixel 3 or newer, or a recent Samsung Galaxy S, Z or A-series flagship, almost certainly — and it must be carrier-unlocked. Dial *#06# and look for an EID number: if one is listed, the phone has an eSIM. Our compatibility list has the full set.
