eSIM Travel Tips for Czechia
Prague is tailor-made for Irish city breakers
Prague is one of the top stag and hen destinations from Ireland and consistently popular for city breaks. Set up your HelloRoam eSIM at home before your Ryanair or Aer Lingus flight. Enable mobile data when you land and you are navigating Prague's beautiful Old Town streets immediately.
Prague public transport is easy with live data
Prague's metro and tram system is excellent and the official Lítačka app gives live route times. Your HelloRoam eSIM keeps the app running in real time from the moment you arrive.
Bohemian Switzerland and spa towns need offline maps
The Bohemian Switzerland national park and spa towns like Karlovy Vary are popular day trips from Prague. Download offline maps for these areas before setting out as signal can be inconsistent in the park's forest and gorge areas.
The Czech Republic uses the Czech Crown, not the euro
Remember the Czech Republic is in the EU but not the Eurozone. Bring Czech Crowns or use card payments. Your HelloRoam eSIM keeps you connected for currency exchange apps and maps to ATMs.
Mobile networks in the Czech Republic: what Irish visitors need to know
HelloRoam connects on Vodafone and O2 in the Czech Republic. Both are major national operators with strong 5G coverage in Prague and 4G across the country. Your eSIM picks the stronger signal automatically.
