Your Czech Republic eSIM runs on O2 and Vodafone, and your phone picks whichever has the better signal. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick O2 or Vodafone by hand.
Czech Republic has three main carriers: O2 Czech Republic (historic state operator, largest nationwide coverage with 5G), T-Mobile Czech Republic (Deutsche Telekom subsidiary, broad urban 5G), and Vodafone Czech Republic (best value). Plugs are Type C and E (standard European with grounding pin, same as Slovakia and Poland), 230V — no adapter needed from the EU. 4G/5G coverage reaches Prague, Brno, Ostrava, Plzeň, Liberec, Olomouc, and most of the ČD (České dráhy) rail network.
Prague Václav Havel Airport (PRG) offers unlimited free WiFi. The currency is the Czech koruna (CZK, ~24.5 CZK/EUR — Czechia has NOT adopted the euro despite EU membership); Česká Spořitelna, ČSOB, and Komerční Banka ATMs accept foreign cards with no commission up to 5000 CZK. Tips are 10%. The Prague Metro (3 lines: A red, B yellow, C green) has 4G at all stations since 2019. Bolt and Liftago are taxi apps (Uber works but less popular). Beware "0% commission" bureaux de change in tourist areas (Václavské náměstí, Old Town) — rates can be 20% worse. Use bank ATMs.
