Data for Prague, trains and hiking
The Czech Republic is in the EU, so a plan from an EU/EEA country should work there at home rates within fair use. For plans from elsewhere, such as the UK, roaming may be charged, so look at your provider's terms. The eSIM is worth having if your allowance is small, you work while travelling or you want to protect your own data. It is data only, and your own number stays active.
The networks are Vodafone and O2. Coverage is generally good in Prague, Brno, Ostrava and the larger towns. Weaker signal is possible in small villages, in the Šumava and Krkonoše mountains and on forest hiking trails.
In Prague data helps with public transport tickets and timetables, ride apps, maps and restaurant bookings. The country uses the koruna, and card payment is common in tourist spots. A local SIM can be bought in a shop, but that means a counter visit, while the eSIM is ready before the trip. The rail network is dense and cheap, and you can check times and tickets in an app. In Prague's old town narrow lanes may dampen the signal, though the connection normally holds.
