Why Google Maps Fails You in South Korea

Planning a trip to South Korea? Whether you're hitting the trendy streets of Hongdae, taking in the view at N Seoul Tower, or grabbing a bite in Itaewon, you're going to need reliable internet to get around.

Why you should skip the physical SIM card

You might think you can just hop from one free Wi-Fi spot to the next, but in South Korea, public Wi-Fi isn't as common as you'd expect.

Without constant data, you'll struggle to use local apps like Naver Map or Kakao Maps. Trust us, you'll need these—they are much more accurate than Google Maps when you're trying to navigate cities like Seoul, Busan, or the busy streets of Gangnam .

Why eSIMs are the way to go

An eSIM is basically a digital SIM card that lives inside your phone. You can set it up before you even board your flight, which saves you from wasting time hunting for a SIM card shop at the airport.

The best part? You can keep your regular SIM card active in your phone, so you won't lose access to your WhatsApp or important messages while you enjoy your local data .

Picking the right plan

When you're shopping for an eSIM, look for plans that give you peace of mind. As of May 2026, many travellers are opting for unlimited data packages so they don't have to worry about running out of internet while exploring. Some providers even offer "Always On" backup data, which keeps you connected for emergencies even if you've used up your main data limit .

A few quick tips for your trip

• Get a T-Money card: Once you land, grab one of these at any convenience store. It makes paying for subways and buses super easy.
• Don't panic at alerts: You might get emergency alerts on your phone. These are just part of the national messaging system. If you get one, just use Google Translate to see what it says .
