Czechia is one of the easiest countries in Europe for a phone. It is covered by the EU's Roam Like at Home rules, and so is every country around it: Germany, Poland, Austria and Slovakia. Travellers with an EU SIM can cross any of those borders without a roaming surprise. Those arriving with a British, American or Asian SIM usually pay a daily fee, and a weekend of maps, tram tickets and restaurant bookings in Prague adds up quickly.
The things to plan for here are different: a currency that is not the euro, transport tickets that live in apps, and mountains where a call can bring rescuers to you.
Key facts for Czechia
- EU roaming: covered by Roam Like at Home
- Local networks: O2, T-Mobile, Vodafone (depending on the plan)
- Emergency numbers: 112; police 158, ambulance 155, fire 150; mountain rescue 1210
- Embassies: in Prague
Prague: trams, tickets and the metro
Prague's public transport sells tickets in the official PID Lítačka app: buy and activate the ticket before boarding the tram, metro or bus, because inspectors check on board. Coverage is strong across the city. For trains to Brno, Český Krumlov or Karlovy Vary, the national railway sells tickets in its app as well, and private operators run some of the main routes.
Paying in crowns
Czechia uses the Czech crown, not the euro. Cards and phone payments are accepted almost everywhere in Prague and in most of the country. When a card terminal or a cash machine offers to charge you in your home currency, choose crowns instead; the conversion it offers is usually more expensive.
Mountains and national parks
The Krkonoše mountains, home of Sněžka, the highest peak in the country, and the sandstone landscapes of Bohemian Switzerland are popular for hiking. Coverage on the main trails is good, but it drops in deep valleys and gorges. The mountain rescue service answers on 1210; save the number before you set off, keep your battery charged and tell someone your route.
Driving
Czech motorways require an electronic vignette, bought online on the official site before you drive; cameras check the number plate. Coverage along the motorways is good, and weaker on minor roads in the hills.
Getting connected
With an EU SIM: your tariff works in Czechia and in every neighbouring country. A travel eSIM is still useful if your plan includes little data outside your own country.
With a SIM from elsewhere: set up a travel eSIM before departure. The plan's days only start with the first Czech connection; your usual number keeps receiving texts, and the transport, train and map apps use the eSIM's data.
A Czech prepaid SIM is sold in operator shops and at many kiosks.
