How much data do you need for your trip?
Pick your trip length and the apps you use each day. You'll see how much data you need and which plan fits. Per-app usage comes from figures published by the app makers and mobile carriers.
For example, 5 days in Korea using maps for 2 h, social media for 1 h and web and messaging for 1 h a day comes to about 0.65 GB a day, or 3.3 GB in total. On Kedanto, South Korea 5GB eSIM ($5.86 USD) fits.
