Complete Guide to Choosing Your Mobile Network, eSIM Plan, and the Best Local Apps in South Korea in 2025 (GPS, Transport, Food, Social Media).

Traveling to South Korea in 2025: Stay Connected with the Right eSIM, SIM Card, Internet Plan, and Mobile Apps

In 2025, traveling to South Korea with your smartphone involves more than just finding a Wi-Fi connection. Although South Korea is ultra-connected, many Western mobile apps don’t work properly: Google Maps is unusable for directions, Uber doesn’t exist, and even the Play Store is sometimes restricted. To fully enjoy your trip, you’ll need a solid South Korea internet plan, the right local mobile apps (often only available on Android or iOS Korea), and know where to download them on your smartphone, tablet, or other mobile device.

Mobile Network, eSIM & Internet Connections

South Korea’s Mobile Network: Top-tier 5G

The top 3 operators are:

• SK Telecom: best rural coverage

eSIM or SIM Card in South Korea? If you have an iPhone, Samsung Galaxy, or any Android device, you can activate a South Korean eSIM directly from your mobile device without visiting a store — the fastest option.

Alternatively, you can purchase a South Korean SIM card at airports or convenience stores like GS25 with your passport.
