Getting Internet in Seoul: A Foreigner's Complete Guide

After three years here, I've helped way too many friends navigate Korea's internet setup, and honestly, it's not as complicated as it seems. Let me break down what actually matters so you don't end up like I did—spending two weeks without WiFi because I didn't understand my contract.

The Big Three Internet Providers

You've got three main options in Seoul:

SK Broadband (SK브로드밴드) — Most popular, most stable

KT (케이티) — Second biggest, also reliable

LG U+ (LG유플러스) — Third option, similar quality

Honestly? They're all basically the same speed and reliability. The real difference is which one your building is wired for. Your landlord or building management office (관리사무소) will tell you which provider(s) are available—you don't get to choose.

Speed & Pricing

This is the good news: internet here is *fast* and *cheap*. You're looking at:

1Gbps fiber: 45,000-55,000 KRW/month

500Mbps fiber: 40,000-50,000 KRW/month

Basic plans: 30,000-40,000 KRW/month

Most apartment buildings have fiber (광섬유), which means gigabit speeds. Your monthly bill will literally be 1/3 of what you paid back home. Beautiful.

How to Actually Sign Up

Step 1: Contact your building's management office

Call or visit in person. Tell them you need internet and ask which providers are available. They usually have a list and might even handle the sign-up for you.

Step 2: Call the provider directly

SK Broadband: 1544-0001

KT: 1544-0010

LG U+: 1544-0010

Step 3: Install appointment

A technician (기사) will come to your apartment within 2-3 days. Takes about an hour. You don't need to do anything except be home.

The Paperwork You Actually Need

Here's where foreigners get stuck: you need either your passport or alien registration card (외국인등록증). Don't show up with just your visa—it won't work. I learned this the hard way.

They might also ask for your apartment lease (전월세 계약서) just to confirm you actually live there.

Hidden Costs to Know About

Installation fee (설치비): Usually free with a 12-month contract, around 50,000 KRW if you want no commitment

Deposit (보증금): Many providers require 50,000-100,000 KRW refundable deposit

Router rental (라우터 렌탈): Usually included, but sometimes 3,000-5,000 KRW extra

Always ask about promotions (프로모션)—there's almost always something going on. During certain seasons, you get free installation + reduced first month cost.

Quick Troubleshooting

If your WiFi cuts out randomly, restart your router (공유기). Seriously, that fixes 90% of problems. To restart: unplug for 30 seconds, plug back in.

If you need help, your provider's app is actually decent. SK Broadband's app and KT's My KT app (마이케이티) both have English language support.

My Personal Recommendation

Get the basic fiber package for your first year. It's plenty fast, super cheap, and you'll save money. After you've settled in and know if you're staying longer, you can upgrade or switch providers when your contract ends.

Welcome to Korea—enjoy your 1Gbps internet! 🚀
