Prague is one of Europe's most popular short-break cities, and Czechia overall works well for trips that also cover neighboring countries. Here's which eSIM to get for your trip.
For a few days in Prague with navigation through the historic center and social media, 2–4 GB is usually enough. For a longer trip that includes Brno and Karlovy Vary with heavy map use, get 5–8 GB or more.
Coverage is fast and reliable almost everywhere in Prague, Brno and Karlovy Vary, including the Prague metro and historic center.
Prague is often combined with a trip to Germany, Austria or Hungary — a Funsim regional Europe plan is more convenient for that kind of route than a separate eSIM per country.
