On the ground
Czechia is led by O2 Czech Republic, T-Mobile Czech Republic and Vodafone Czech Republic, all with strong nationwide 4G.
T-Mobile and Vodafone have pushed 5G into Prague, Brno and Ostrava, while O2 keeps particularly deep rural 4G reach.
Prague's historic centre, from Old Town Square to the Castle, has consistently strong signal on every operator.
Coverage weakens in the Bohemian and Moravian border forests and pockets of Sumava National Park near Bavaria.
Popular destinations
Prague is the clear highlight, from Charles Bridge and the Astronomical Clock to the sprawling castle complex.
Cesky Krumlov's fairy-tale old town is the favourite day trip, with reliable coverage despite its size.
Brno offers a livelier, less touristy alternative with a strong student and cultural scene.
Karlovy Vary's spa town charm and the wooded Sumava National Park round out the quieter attractions.
Local or regional
A Czechia-only eSIM suits travellers focused on Prague and day trips such as Cesky Krumlov or Kutna Hora.
The country's central position means many itineraries extend into Austria, Germany or Poland.
For central European loops, a Europe regional plan avoids switching profiles at each border.
If Prague is your only stop, the dedicated Czechia plan stretches your data further.
