The Czech Republic's EU membership means roaming rules apply but a HelloRoam eSIM gives you a local data connection from the moment you land at Václav Havel Airport.
- HelloRoam connects to O2 5G, Vodafone 5G in Czechia

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.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
