eSIM Travel Tips for Czechia
Prague Old Town and tourist apps

Cesky Krumlov day trip
The fairy tale town of Cesky Krumlov in South Bohemia is a popular day trip from Prague. Coverage is solid in the town centre. The scenic countryside between Prague and Cesky Krumlov is generally well covered along main roads.
Czech Republic as a Central Europe hub

Czech beer and food culture
Czech Republic produces some of Europe's best beer, including Pilsner Urquell. Finding the right beer hall or traditional hospoda requires local review apps and Google Maps. Having data running helps avoid tourist trap restaurants around Old Town Square.
Budget destination with good infrastructure
The Czech Republic is significantly more affordable than Western Europe for Australians. Beer costs around AU$2.50 in a local pub. Having data keeps you informed on prices and helps find the local spots rather than the tourist-priced alternatives.

HelloRoam eSIM vs Australian carrier roaming in the Czech Republic

| Category | HelloRoam eSIM Recommended | Czech SIM card | Telco roaming |
|---|---|---|---|
| Typical cost | From A$3.32 total | A$11.36–A$28.39 total | — |
| Details | Plans start at A$3.32. Buy before your long flight, activate at home, and arrive at Prague Airport already connected. | T-Mobile and O2 SIMs are available at Prague Airport. They work well but add time on arrival. | Telstra's International Day Pass adds a fee for every day you roam in the Czech Republic.

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.
