How to choose a data plan in South Korea?

When choosing a data plan in South Korea, start by considering the length of your stay and how you use your phone. If you mainly use maps, messaging apps, and email, a smaller data plan will suffice. If you watch videos, work remotely, send files, or share a hotspot, you’ll need a larger data limit.

Personal hotspots are supported, but connecting a laptop, tablet, or someone else’s phone can use up your data faster. Therefore, if you plan to use the internet heavily, it’s better to choose a larger GB plan for South Korea rather than skimp on the data limit.

If you only need internet access for basic tasks during your vacation in South Korea, check out a basic data plan. However, if your trip is going to last longer and your phone will be your main tool for organizing your trip, consider a large data plan for South Korea.
