Data for Prague, Brno and the castle towns, installed before you fly. Czechia is on the Europe plan, so the same eSIM keeps working in the Prague metro, on the train to Vienna or Dresden and over all four borders. Crowns for the beer, nothing to change for the data.
The Czech Republic plan covers Czech Republic only.
The same 10 GB in a package that keeps working past Czech Republic.
38 other countries share the package with Czech Republic. A few of them:
What's included, when it starts, and how to get connected.
Czechia gave the world the word 'robot', and Prague still has no train to its airport. The way into town is a trolleybus or a bus to the metro, and it is quicker than it sounds.
Install your onesim eSIM over Wi-Fi and leave the line switched off until you land. Download the PID Lítačka app while you are still on Wi-Fi: since January 2026, tickets bought in it cost less than paper ones. On a non-EU passport, the EU's Entry/Exit System takes your fingerprints and photo at your first Schengen border, so allow a few extra minutes.
When the plane has parked, open Settings → Mobile Data, switch the onesim line on, choose it for data and turn data roaming on for that line only. The phone finds a Czech network within a minute or so, and that first connection starts the package. Your home SIM stays in with its own roaming off, so calls and texts to your usual number still arrive.
Trolleybus 59 leaves every few minutes for Nádraží Veleslavín on metro line A, about 15 minutes away; bus 100 runs to Zličín on line B. One 90-minute ticket — 46 CZK in the app, 50 CZK on paper — covers the bus and the metro into the centre. The Airport Express to the main station needs its own 200 CZK ticket; at night, buses 907 and 910 take over.
Buy the ticket before you board — from the machine at the stop, which takes contactless cards, or in the app — and stamp a paper one in the yellow validator. On trams and city buses you can also tap a card at the terminal on board; use the door marked with the contactless symbol. The airport's official taxi partner is Uber, booked in the app, at a kiosk or at the counter.
The chimney cakes turning on spits all over the Old Town are sold as an 'Old Bohemian' tradition, but the stalls have only spread through Prague since the early 2000s. The pastry comes from the old Kingdom of Hungary, and its protected version, Skalický trdelník, is Slovak. Eat one if you like, then find a bakery and try a koláč, the pastry Czechs actually grew up on.
Zach Cregger's Resident Evil, in cinemas since September 2026, was shot in Prague, and one of its biggest monster sequences plays out around the Negrelli Viaduct in Karlín, a railway bridge from 1850 you can walk under for free. Netflix has used the city as 1870s New York for The Age of Innocence, and Nosferatu (2024) filmed at Barrandov Studios and Pernštejn Castle.
Krumlov is as pretty as its photographs, and as crowded: a town of under 13,000 people that fills with coach day trips, and that a Czech ranking of tourist traps called 'a theme park in disguise'. Telč, in the Vysočina highlands, has a UNESCO-listed square of Renaissance and Baroque gables over arcades, and a fraction of the visitors. If you do go to Krumlov, sleep there.
Czechia is in the EU but pays in koruna (CZK), and no government has set a date for the euro. Cards work almost everywhere. When a card machine or a cash machine offers to charge you in your home currency, say no; the rate is worse. Changed cash at a bad rate anyway? Czech law gives you three hours to cancel an exchange of up to €1,000, receipt in hand.
The old joke survives 2026 prices: in an ordinary Prague pub a half-litre of lager costs about 55–70 CZK, a 0.3-litre bottle of mineral water 40–60. Czechia has drunk more beer per head than any other country for 32 years running. The tap water is safe, but restaurants rarely pour it free — ask for kohoutková voda and expect to pay about what a small beer costs.
Answers about data, coverage and setup for Czech Republic.
In Czechia itself, usually not: roam-like-at-home applies, within your plan's fair-use allowance. The package is for everyone else — visitors from the UK, the US, Switzerland, Türkiye or the Western Balkans, whose tariffs usually charge by the day or by the megabyte here — and for EU travellers with a small allowance, or a trip that carries on beyond the EU.
Yes. All four of Czechia's neighbours — Germany, Austria, Poland and Slovakia — are on the Europe plan, so the day trip to Dresden, the train to Vienna or the drive to Kraków carries on with the same package and the same allowance. The phone moves to a partner network a minute or two after the border; nothing restarts and there is nothing to switch.
Not from this eSIM: it is data-only, and Prague's SMS tickets only work from Czech mobile numbers anyway, at a higher price than the app. Use the PID Lítačka app, which runs on mobile data and takes a bank card, or tap a contactless card at the ticket machines and on board trams and city buses. The signal reaches every metro station and tunnel, so the app works underground too.
