Prices are live and may change. Google Fi is excluded from the value ranking because it is a full phone plan rather than a travel data plan.
O2, T-Mobile and Vodafone all run 5G across central Prague, Vinohrady, Smíchov and the touristed Old Town. The Prague Metro has cell coverage on all three lines, including the deepest stations on Line C.
5G is fully live across Brno's city core. Vodafone has the strongest 5G availability along the D1 motorway between Prague and Brno; T-Mobile leads on raw speed in central Brno.
The Český Krumlov old town and main tourist circuits are well covered. České Budějovice and Tábor are fully on 4G/5G. Smaller villages between them rely on T-Mobile for the most consistent signal.
National park gateways, the Pravčická brána viewpoint and Špindlerův Mlýn ski area all hold signal at the visitor centres. Deep-forest trail interiors and the Sněžka summit road see intermittent service.
O2 and T-Mobile patch on the main routes. Smaller side roads through Šumava National Park forest and the Moravian Karst caves drop coverage; trekking days should plan to be offline.
Prague
- Arriving
- Václav Havel Airport Prague (PRG) is about 17 km west of the centre. There is no rail link yet (one is under construction), so the transfer is bus 119 to the Nádraží Veleslavín metro station on Line A, or the Airport Express bus to the main station (Hlavní nádraží). All terminals have full 5G from O2, T-Mobile and Vodafone. As an EU country, European regional eSIMs work here at no surcharge.
- On the subway and rail
- The Prague Metro (Line A green, Line B yellow, Line C red) has cell coverage on every line, including the deep escalator stations on Lines A and C. The dense tram network and the city buses stay connected throughout. The PID Lítačka app handles tickets and routing and needs data. Coverage holds across the Vltava bridges between the Old Town and Malá Strana.
- Free public WiFi
- The malls leave WiFi open: Palladium by Náměstí Republiky and Nový Smíchov across the river. The Old Town Square and Wenceslas Square areas have hotspots in the larger cafes and hotels. Restaurants across Vinohrady and Žižkov offer WiFi with a purchase. PRG airport has free terminal WiFi. Hotels provide guest WiFi as standard.
- Coverage in the city
- O2, T-Mobile and Vodafone all run 5G across central Prague, Malá Strana, Vinohrava and Žižkov. Charles Bridge, Prague Castle, the Astronomical Clock and the Old Town lanes are densely covered. The funicular up Petřín Hill and the riverside promenades stay connected. The intercity trains to Brno, Český Krumlov and Vienna hold data through the main corridors.
- If you prefer a local SIM
- O2, T-Mobile and Vodafone, plus the budget brands Kaktus and Mobil.cz, sell prepaid SIMs at PRG and across the city. Prepaid does not require registration in Czechia. Tourist data is affordable. For most visitors a European regional eSIM is the simplest choice, covering Czechia alongside Austria, Germany and Poland.
Český Krumlov
- Arriving
- The nearest airports are Prague (PRG) about two and a half hours north and Linz in Austria (LNZ) about an hour south. The standard arrival is a direct shuttle bus or a train from Prague via České Budějovice; both hold signal along the route. The town itself is tiny and walkable, set on a tight bend of the Vltava. Have data ready so maps work in the cobblestone lanes.
- On the subway and rail
- Český Krumlov has no public transit within the town, which is compact and pedestrian-focused around its UNESCO old centre. Trains and buses link it to Prague and České Budějovice. The historic core, the castle complex and the riverbank are all explored on foot. Rafting and canoeing trips on the Vltava through and below the town stay connected near the centre.
- Free public WiFi
- Hotels, pensions and restaurants throughout the old town and the castle visitor centre provide guest WiFi. Cafes along the river and around the main square (Náměstí Svornosti) offer WiFi with a purchase. Connectivity is concentrated in the small historic core, so a working eSIM or SIM is worth having for the day trips out.
- Coverage in the city
- O2, T-Mobile and Vodafone all cover the UNESCO old town, the castle and tower, and the Vltava riverbanks. The Egon Schiele Art Centrum, the Baroque theatre and the cliffside viewpoints are all connected. Signal holds on the short rafting stretches through town; longer paddles downstream toward Zlatá Koruna thin out between villages.
- If you prefer a local SIM
- The town has limited carrier shops, so it is easier to buy a SIM in Prague or České Budějovice on the way, or arrive on an eSIM. Czech prepaid needs no registration. A European regional eSIM is the cleanest option for a Český Krumlov stop on a wider Central European trip.
Grab an eSIM before you arrive in Czech Republic to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.
The Czech Republic provides solid mobile connectivity for eSIM travelers exploring Prague and beyond. O2, T-Mobile, and Vodafone operate extensive networks with 5G coverage in Prague and Brno, while dependable 4G LTE covers the rest of the country including popular tourist regions like Bohemia and Moravia. The compact size of the country means coverage gaps are minimal, and most highways and rail lines maintain consistent signal.
EU roaming regulations apply, making European regional eSIM plans a practical choice for visitors combining the Czech Republic with neighboring countries like Austria, Germany, or Poland. Prague's excellent public transit integrates well with mobile data for real-time navigation and ticketing apps. Rural areas and deep forest regions like Bohemian Switzerland may see reduced speeds but rarely lose connectivity entirely.
- EU regional plans work well here - ideal if visiting neighboring Austria, Germany, or Poland too
- Prague public transit apps like PID Litacka are useful for getting around - data makes them seamless
- Coverage is reliable on trains between Prague, Brno, and Cesky Krumlov routes
- Download offline maps for hiking areas in Bohemian Switzerland and Sumava national parks
- Free Wi-Fi is widely available in Prague cafes, hotels, and shopping centers

- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the Czech Republic eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Decide on your dual-SIM strategy.
Keep your home line on for SMS-based bank logins, two-factor codes, and emergency calls. Set the travel eSIM as the data line only. Most modern phones can do both simultaneously.
- 4
Disable iMessage on the travel eSIM line.
Otherwise iMessage will try to re-activate against the new line on arrival and you will spend the first ten minutes troubleshooting it instead of finding the taxi rank.
- 5
Download offline maps for Czech Republic.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.
We are building this section from real, verified traveler submissions rather than stock testimonials, so it stays empty until we have notes we can stand behind. If you have used an eSIM in Czech Republic recently, a one-paragraph note on what worked (and what did not) helps the next traveler.
