Korea has some of the fastest internet in the world, and for foreigners setting up home internet here, the speeds and prices are genuinely jaw-dropping. The catch? Getting it set up as a non-Korean speaker is a whole other story.
I moved into my first apartment in Seoul a few months back. I knew I needed to sort out internet pretty quickly — working from home meant I couldn't just sponge off café WiFi forever. What I didn't know was how much bureaucratic friction was waiting for me between "I need internet" and "the WiFi actually works."
The Part Nobody Tells You About First
Here's the thing about Korean internet: there are three main providers — KT GiGA 인터넷, SK Broadband, and LG U+. Everyone online has an opinion about which one is best, and honestly, most of that advice is written by people who speak Korean. If you don't, the calculus changes completely.
KT is the one you want if you're not fluent in Korean. It's the only provider with any real English support — you can call 100 and eventually reach someone who can help in English. It's not perfect, not by a long shot, but it exists. SK Broadband and LG U+ have essentially zero English customer service. As someone on Reddit put it: "If you can't speak Korean at all, or have nobody to help, probably stick to KT."
That said, SK Broadband is worth considering if you're already an SKT mobile subscriber. The bundle discounts can bring a 1Gbps plan down to around ₩32,000 a month on a three-year contract, which is genuinely competitive. And LG U+ plays a different game entirely — they're aggressive with cash incentives to win you over as a customer. We're talking ₩300,000 to ₩350,000 cash back when you switch to them, which is real money. My wife called around when our three-year KT contract expired and LG offered a cheaper monthly rate plus ₩350,000 cash. Hard to say no to that.
But for your first contract, in a new country, with limited Korean? KT. Just KT.
What You Actually Need to Sign Up
Before you walk into any 통신사 (that's what Koreans call the telecom stores), you need three things: your 외국인등록증, or ARC card — the foreigner registration card you got from immigration — a Korean phone number, and a Korean bank account.
No ARC card, no contract. That's just how it is. If you're still waiting for yours, skip down to the temporary solutions section near the end of this post.
The Korean phone number and bank account are for identity verification and auto-payment setup. The bank account part surprised me a bit — Korean internet billing almost always runs on 자동이체, automatic bank transfer, rather than card payments. Make sure you have your account details ready, ideally with your bank's official Korean document showing the account number.
The Store Visit: Bring Someone If You Can
My Korean at the time was somewhere between "can order coffee" and "can read a menu slowly." The KT store near my apartment became an unexpected test of my phrasebook app's limits.
The staff at the local store were friendly enough, and I muddled through with a combination of Google Translate, pointing at things, and a lot of nodding. But I'll be honest — I probably agreed to things I didn't fully understand in the moment. I got lucky that nothing went badly wrong. If you can bring a Korean-speaking friend, do it. Even thirty minutes of their time can save you real headaches.
One thing worth knowing: go to the store closest to your apartment building. The staff there often know the building — which floors have which wiring setup, what speeds are actually available in your unit. It's a small thing but it does make a difference.
At the store, you'll pick your speed tier. The options are typically 100Mbps, 500Mbps, or 1Gbps. Price-wise, 100Mbps runs around ₩20,000 to ₩25,000 a month, 500Mbps sits somewhere in the ₩25,000 to ₩30,000 range, and full gigabit comes in at roughly ₩30,000 to ₩35,000 a month. Those prices assume a three-year 약정, or contract — one-year contracts are slightly more expensive. For context, that's a gigabit connection for about twenty-five US dollars. I had been paying over a hundred dollars a month for 200Mbps back home. Korea really is a different world.
You can also bundle internet with cable TV (B tv is SK Broadband's TV service) and a landline phone. Bundles typically run ₩40,000 to ₩60,000 a month. Unless you genuinely want Korean cable TV, I'd skip the bundle.
Installation Day: You Have to Be There
After signing up, a technician visit gets scheduled. Here's where things got slightly messy for me.
The salesperson told me I didn't necessarily need to be home — that the technician could sometimes access the building's 단자함, the utility closet where all the cables terminate, without entering my unit. I found out later this was not accurate. A Redditor described an almost identical situation: "The guy at the service center admitted the guy at the store lied to get me to sign a contract." The technician will need to come inside your apartment. Block off that time and be there.
The installation itself is usually quick. The 기사님, or technician, runs the cable, sets up the router, checks the connection, and is generally out within an hour. They speak Korean, obviously, but the work itself is pretty self-explanatory — they'll test the connection before they leave.
Run a Speed Test. Seriously.
The first thing I did after the technician left was open speedtest.net. And I'm glad I did.
I had signed up for a 1Gbps plan. My speed test showed 99Mbps. Not 999. Ninety-nine.
I immediately thought I'd somehow signed up for the wrong plan, or that there was a billing mistake. Turned out the issue was actually with the router — the one the technician set up defaulted to a slower configuration and needed to be adjusted. A quick call sorted it out (this was one of those moments where having KT's English support, limited as it is, helped). But if I hadn't run that speed test, I might have gone months paying for gigabit speeds and getting a tenth of that.
It's a well-known enough issue that you'll find multiple Reddit threads about it. "I was only getting 99Mbps when I paid for 1Gbps. Always run a speed test." Note your contracted speed tier before the technician leaves. Run speedtest.net the moment the connection is live. If the numbers don't match, call immediately while everything is fresh.
While You're Waiting for the Technician
If you've just moved in and haven't sorted internet yet, you've got a few options to bridge the gap.
The easiest short-term solution is renting a pocket WiFi device called an 에그. You can pick one up at Incheon Airport arrivals the moment you land. Rental typically costs between ₩3,000 and ₩5,000 a day, and they work well enough for a few weeks while you get your ARC card and set up your home connection. The downside is you're tethered to a device you have to remember to charge.
If you have a Korean SIM with data, you can use 핫스팟 — mobile hotspot — to share your phone's data connection with your laptop or other devices. Not great for heavy usage, and data caps will catch up with you, but it's genuinely fine for a week or two.
And of course, Korean cafes have free WiFi everywhere. It won't solve your work-from-home problem permanently, but it'll keep you connected while things get sorted.
When Your Contract Ends, Don't Just Renew
The last thing I'll say: when your 약정 ends — whether that's after one year or three — don't let the ISP auto-renew you at their new rate without checking your options first.
Every ISP raises their rates at renewal. It's basically a given. And the competition between KT, SK Broadband, and LG U+ means there's almost always a better deal available if you're willing to switch. LG U+ in particular is known for dangling those cash incentives in the ₩300,000 range to lure customers from the other providers. Have someone call around and see what's on offer.
Your first contract is about getting something that works. Your second contract is about getting a good deal. Those are genuinely different priorities, and Korea's internet market is competitive enough that you'll have options.
Getting internet in Korea as a foreigner takes a bit of work, more than it probably should. But once it's running? You'll forget what slow internet even felt like.
